The integration with its own brand&#8217;s printers is obvious (fine-tuned profiles, Prusa Connect, Printables), but it works just as well with a printer running Marlin or Klipper.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">At 3Dwork we have used it since its early versions, and this guide covers what is worth knowing to get the most out of it. The first part is for people just starting out: what a slicer is, how to install PrusaSlicer and how to go from an STL to a file ready to print. The second is for users with some mileage: the everyday features and the advanced tools that make a difference. Menu and button names are those of the English interface.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/3dwork.io\/wp-content\/uploads\/2026\/10\/prusaslicer-modelo-cama-mk4s.webp\" alt=\"Model of a black and orange rocket engine placed on the virtual bed of a Prusa MK4S printer in PrusaSlicer\" title=\"- -\"><figcaption class=\"wp-element-caption\">A multicolor model prepared in PrusaSlicer. Screenshot of PrusaSlicer, \u00a9 Prusa Research (prusa3d.com)<\/figcaption><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">What a slicer is and what it does<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A 3D printer does not understand 3D models. What it runs is a list of very simple commands: move to this point, at this speed, extruding this much plastic, at this temperature. That list is called <strong>G-code<\/strong> and it is generated by a program called a <strong>slicer<\/strong>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A slicer does three things:<\/p>\n\n\n\n<ol class=\"wp-block-list\"><li><strong>It cuts the model into horizontal layers<\/strong> of the thickness you choose (the layer height).<\/li><li><strong>It calculates the toolpaths<\/strong> for each layer: the outer walls (perimeters), the interior infill, the solid top and bottom layers and, if needed, the supports for the areas that would otherwise hang in the air.<\/li><li><strong>It translates everything into G-code<\/strong> using the settings for your printer and your filament: temperatures, speeds, fan, retractions.<\/li><\/ol>\n\n\n\n<p class=\"wp-block-paragraph\">That is why the same STL can come out very well or very badly depending on how you slice it. Mastering the slicer is half of the result.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Where PrusaSlicer comes from<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Its origin is Slic3r, a project that Alessandro Ranellucci started in 2011. Prusa created its own branch, Slic3r Prusa Edition, in November 2016, and in May 2019 renamed it PrusaSlicer 2.0, because it had already drifted a long way from the original Slic3r. It is free software under the AGPLv3 license, its code is on GitHub, it does not require you to create an account, and it works for both FDM and resin (SLA), although this guide focuses on FDM.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In the first version of this guide, in 2020, we compared it with Simplify3D, which was then the paid reference. Today that comparison no longer makes sense.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Where to download PrusaSlicer: versions and systems<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Always download it from official sources: the PrusaSlicer page on prusa3d.com, Prusa&#8217;s Drivers &amp; Apps package, or the <em>releases<\/em> section of the GitHub repository.<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li><strong>Windows:<\/strong> .exe installer, or a .zip if you prefer not to install. The Drivers &amp; Apps package also includes test models and drivers; you can install only PrusaSlicer.<\/li><li><strong>macOS:<\/strong> .dmg image. You install it by dragging the application into the installer window.<\/li><li><strong>Linux:<\/strong> the official channel is Flatpak through Flathub. Install Flatpak, add the Flathub repository and install PrusaSlicer from your distribution&#8217;s software center or from the terminal. If you do not have administrator permissions, you can do everything with the <code>--user<\/code> option.<\/li><\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Two branches coexist today. <strong>PrusaSlicer 2.x<\/strong> is the stable one and the one you should use to print (the latest version is 2.9.6, from June 2026). <strong>PrusaSlicer 3.x<\/strong> is in alpha: it brings a new interface, but it is not finished yet; we summarize it at the end. Test versions keep their profiles in a different folder, so they can be installed without messing up the configuration of the stable one.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Getting started with PrusaSlicer<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">The configuration wizard<\/h3>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/3dwork.io\/wp-content\/uploads\/2026\/10\/prusaslicer-asistente-bienvenida.webp\" alt=\"Welcome screen of the PrusaSlicer configuration wizard with the full list of steps on the left, from login to view mode\" title=\"- -\"><figcaption class=\"wp-element-caption\">Welcome page of the configuration wizard, with all its steps on the left (English interface).

To get back to it later, for example to add another printer, go to <strong>Configuration &gt; Configuration Wizard<\/strong>. Yes, it goes by two different names depending on the platform. Its steps:<\/p>\n\n\n\n<ol class=\"wp-block-list\"><li><strong>Welcome.<\/strong> It includes an option to delete all user profiles, useful if you want to start from scratch.<\/li><li><strong>Log in with Prusa Account (optional).<\/strong> If you log in, PrusaSlicer downloads profiles automatically and enables Prusa Connect. You can skip it.<\/li><li><strong>Configuration sources.<\/strong> If you have not logged in, you choose between Prusa&#8217;s online sources or loading profiles from a local file.<\/li><li><strong>Printer profiles.<\/strong> There are pages for Prusa printers, another one for <strong>printers from other manufacturers<\/strong> (you pick the brand and then the model) and an option to define a <strong>custom printer<\/strong> if yours does not appear.<\/li><li><strong>Filaments.<\/strong> Grouped by compatible printer, material type and manufacturer. Those marked with an asterisk are not compatible with one of your printers.<\/li><li><strong>Updates, downloads and file association.<\/strong> Update checks, opening Printables.com models with one click, and PrusaSlicer as the default program for 3MF and STL.<\/li><li><strong>View mode.<\/strong> Level of detail of the interface, and metric or imperial units.<\/li><\/ol>\n\n\n\n<p class=\"wp-block-paragraph\">Everything you choose here can be changed later, so there is no need to get it right the first time.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">The interface, piece by piece<\/h3>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/3dwork.io\/wp-content\/uploads\/2026\/10\/prusaslicer-interfaz-plater.webp\" alt=\"PrusaSlicer interface with the main elements numbered: top bar, left-hand tools, right-hand profile panel, context menu and Slice now button\" title=\"- -\"><figcaption class=\"wp-element-caption\">Main PrusaSlicer interface with its parts numbered.

In the Plater, the 3D view takes up almost the whole screen and around it you will find this:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li><strong>Top bar:<\/strong> Add, Delete, Delete all, Arrange, copy and paste, instances, variable layer height, Undo and Redo.<\/li><li><strong>Left bar:<\/strong> Move, Scale, Rotate, Place on face and Cut, plus the painting tools (supports, seams, multimaterial) and the measure tool.<\/li><li><strong>Right panel:<\/strong> the three profile selectors and the most-used quick settings (Supports, Infill and Brim), the object list with its position and size, and the <strong>Slice now<\/strong> button.<\/li><li><strong>Bottom left corner:<\/strong> the switch between the 3D view and the layer preview. It can also be toggled with the Tab key.<\/li><li><strong>Top right:<\/strong> the mode selector and the Prusa Account login.<\/li><\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Two notes on the Spanish translation of the interface: the <em>Brim<\/em> option (extra loops around the first layer to improve adhesion) appears there as <strong>Balsa<\/strong>, which is not the same as a real raft, and the print bed almost always appears as &#8220;base&#8221;.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Importing the model<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Drag the file into the window, use the Add button in the top bar, or go to <strong>File &gt; Import<\/strong>. PrusaSlicer supports STL, STEP, 3MF, OBJ and AMF. If the model comes from Printables, you can open it directly from the Printables tab (we cover it below).<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Move, scale and rotate<\/h3>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/3dwork.io\/wp-content\/uploads\/2026\/10\/prusaslicer-herramienta-mover.webp\" alt=\"PrusaSlicer Move tool active on a green model, with colored arrows for each axis on the bed of a Prusa MK4\" title=\"- -\"><figcaption class=\"wp-element-caption\">Move tool: each arrow shifts the part along one axis.

Select the model, press the F key or choose <strong>Place on face<\/strong> in the left bar, and click one of the white planes that appear: that face now rests on the bed. A good orientation reduces supports, improves the finish and makes the part stronger in the direction that matters.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Slicing and checking the preview<\/h3>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/3dwork.io\/wp-content\/uploads\/2026\/10\/prusaslicer-laminar-ahora.webp\" alt=\"Model placed on the PrusaSlicer virtual bed with arrows pointing to the 3D view and preview switch and the Slice now button\" title=\"- -\"><figcaption class=\"wp-element-caption\">Bottom left, the switch between 3D view and preview; bottom right, the Slice now button.

If PrusaSlicer detects an SD card or a USB drive, the <strong>Export to SD card \/ Flash drive<\/strong> button appears next to it, which targets that drive directly, and a button to eject it when finished. If your printer is on the network, you do not need to go through the card: we explain that in the everyday features.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">PrusaSlicer profiles: print, filament and printer<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Everything PrusaSlicer needs to know in order to slice is split across three profiles, which are always active and are chosen in the right panel: <strong>print<\/strong>, <strong>filament<\/strong> and <strong>printer<\/strong>. Separating them has a huge advantage: if you change material you only change the filament profile, and if you want more quality on a specific part you only touch the print profile, without redoing everything else. The network connection is separate, in the <strong>physical printer<\/strong>, which is not part of these three profiles.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Each profile is edited in depth in its own tab (<strong>Print Settings<\/strong>, <strong>Filaments<\/strong> and <strong>Printers<\/strong>), with its settings grouped into pages on the left. If this is your first printer, the logical order is: printer (once), filament (one per material) and print (the one you choose for each job).<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Print profile: how the part is printed<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">It defines the printing strategy. Its pages are Layers and perimeters, Infill, Skirt and brim, Support material, Speed, Multiple Extruders, Advanced, Output options, Notes and Dependencies. It is the profile you will change the most: it is normal to have several (a fast one, a detail one, a strong one) and choose according to the part. These are the settings worth mastering first.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Layer height<\/strong> (Layers and perimeters)<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/3dwork.io\/wp-content\/uploads\/2026\/10\/prusa-altura-capa-comparativa-rana.webp\" alt=\"The same frog figure printed with 0.10, 0.20 and 0.30 mm layers, with close-ups of the surface and the print time of each\" title=\"- -\"><figcaption class=\"wp-element-caption\">Detail and print time with 0.10, 0.20 and 0.30 mm layers.

It is what most affects print time and vertical resolution: taller layers print much faster, but they are more noticeable.<\/li><li><strong>When to change it:<\/strong> depending on the part. To start with, Prusa&#8217;s help recommends 0.15 or 0.20 mm; it advises against going below 0.10 mm, because the improvement is small and the time skyrockets, and it notes that the layer should stay below 80% of the nozzle diameter.<\/li><li><strong>A nuance:<\/strong> layer height only changes the vertical resolution. Embossed text parallel to the bed looks the same with any layer height; to gain detail in the XY plane you need a finer nozzle.<\/li><\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Perimeters<\/strong> (Layers and perimeters)<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/3dwork.io\/wp-content\/uploads\/2026\/10\/prusaslicer-perimetros-2-4-8.webp\" alt=\"Three PrusaSlicer preview views with walls of 2, 4 and 8 perimeters\" title=\"- -\"><figcaption class=\"wp-element-caption\">Walls with 2, 4 and 8 perimeters in the preview.

According to Prusa, strength depends mostly on the perimeters and not on the infill, so it is the first thing to increase for a stronger part. On the same page are the top and bottom solid layers, which close the part at the top and bottom.<\/li><\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Infill: density and pattern<\/strong> (Infill)<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/3dwork.io\/wp-content\/uploads\/2026\/10\/prusaslicer-relleno-giroide.webp\" alt=\"Hexagonal part with gyroid infill, half in the PrusaSlicer preview and half printed in orange\" title=\"- -\"><figcaption class=\"wp-element-caption\">Gyroid infill in the preview and in the printed part.

The infill supports the upper layers and affects time, filament use and stiffness.<\/li><li><strong>Density:<\/strong> according to Prusa&#8217;s help, most models print well with 10 to 15%, and it is rarely necessary to go above 30%. Raise it if you are after more weight, stiffness or compression resistance. At 100% the pattern switches to rectilinear and the appearance may get worse.<\/li><li><strong>Pattern:<\/strong> there are many. Gyroid is Prusa&#8217;s favorite: strong in all directions, fast, and with no crossings within the same layer. Adaptive cubic puts more infill near the walls and less in the center, useful on large parts. For visible faces there are dedicated top and bottom layer patterns.<\/li><\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Supports<\/strong> (Support material)<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/3dwork.io\/wp-content\/uploads\/2026\/10\/prusaslicer-soportes-base-vs-todos.webp\" alt=\"Two PrusaSlicer previews of a bust with supports in green: on the left only from the bed and on the right everywhere\" title=\"- -\"><figcaption class=\"wp-element-caption\">Supports from the build plate only (left) and everywhere (right).

Its pages are Filament, Cooling, Advanced, Filament Overrides, Custom G-code, Notes and Dependencies. Ideally you have one per material and, if you fine-tune, per brand or color, because behavior changes from one spool to another. Always start from a system profile for the same type of material (PLA, PETG&#8230;) and adjust it with the calibrations in the next section.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Temperatures, flow, density and cost<\/strong> (Filament)<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/3dwork.io\/wp-content\/uploads\/2020\/03\/PrusaSlicer11.jpg\" alt=\"Filament page of the filament profile in PrusaSlicer with color, diameter, extrusion multiplier, density and extruder and bed temperatures\" title=\"- -\"><figcaption class=\"wp-element-caption\">Filament page: diameter, extrusion multiplier, density, and extruder and bed temperatures.

It is key on overhangs and bridges, but with some materials cooling too much causes warping or layers that separate.<\/li><li><strong>Keep fan always on:<\/strong> according to Prusa, it is usually enabled for almost all materials, except ABS, ASA, PC and some flexibles.<\/li><li><strong>Speeds and thresholds:<\/strong> with auto cooling, the fan and the speed adapt to the time each layer takes.

Prusa mentions between 1 and 5 layers without fan depending on the filament.<\/li><\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Filament Overrides<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\"><li><strong>What it controls:<\/strong> it lets the filament profile replace retraction settings of the printer profile, such as the length or the Z lift.<\/li><li><strong>When to use it:<\/strong> with materials that need a different retraction from the usual one, such as flexibles, without having to create another printer profile.<\/li><\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">System profiles and your own profiles<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The profiles that PrusaSlicer ships with, the system ones, appear with a padlock and are updated online. They are not overwritten: to change one, click the cog next to the selector, choose <strong>Edit preset<\/strong>, make your changes and save them with the save icon and a name of your own. That way you have your version without losing the original, and you can go back to it if something goes wrong.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The print and filament profiles have a <strong>Dependencies<\/strong> page that indicates which printers they are compatible with; PrusaSlicer uses it to show you only what fits the selected printer. If you are missing a filament, most likely it is not marked as compatible. To take your profiles to another computer, <strong>File &gt; Export<\/strong> lets you save the current configuration or the complete set of settings.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Normal and advanced settings: the view modes<\/h3>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/3dwork.io\/wp-content\/uploads\/2026\/10\/prusaslicer-selector-modo.webp\" alt=\"PrusaSlicer mode dropdown open at the top right, with Beginner, Normal and Expert modes marked in green, yellow and red\" title=\"- -\"><figcaption class=\"wp-element-caption\">Mode selector in the top right corner (English interface). Screenshot of PrusaSlicer, \u00a9 Prusa Research (help.prusa3d.com)<\/figcaption><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">Each profile has hundreds of parameters, and PrusaSlicer does not show them all at once. What you see depends on the view mode, which is changed in the <strong>dropdown in the top right corner<\/strong> (available in all tabs) or on the View mode page of the configuration wizard.<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li><strong>Beginner mode<\/strong> (in the wizard, Simple mode): only the most-used settings. Complex features such as modifiers are hidden.<\/li><li><strong>Normal mode<\/strong> (in the wizard, Advanced mode): more parameters and tools such as paintable supports and seam painting, which only appear from this mode up.<\/li><li><strong>Expert mode:<\/strong> everything, including the settings meant for creating the profile of a new printer. Several of the infill, skirt and brim, or supports options we have seen only appear here.<\/li><\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The names change depending on where you look: the 2.x dropdown uses Beginner, Normal and Expert; the wizard, Simple, Advanced and Expert; and Prusa&#8217;s official help, Simple, Advanced and Expert. They are the same three levels. In addition, each parameter carries a colored dot: <strong>green<\/strong> for what a beginner can touch without fear, <strong>yellow<\/strong> for experienced users and <strong>red<\/strong> for expert settings.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Our advice: start in Beginner mode with a system profile and move up a level when you need a specific setting. If you do not know what a parameter does, hover over its name and an explanation will appear.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Profiles in 3.x<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The 3.x alpha changes this system quite a bit. Profiles move to YAML format and adapt to the real configuration of the machine: on a multi-head printer, for example, the diameter of each nozzle is chosen in the printer selector itself instead of creating one profile per combination. A fourth profile appears, the <strong>tool print<\/strong> (<em>ToolPrint<\/em>) profile, with the print settings that can differ on each head; with single-head printers it stays hidden. In addition, each bed in a project can have its own configuration, and colors are saved in the project instead of in the profiles.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Tests and calibrations<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">System profiles are a good starting point, but they do not know your filament. Prusa says it clearly in its help: the ideal flow value changes with each material and each color, and even from one spool to another. Calibrating means printing test parts designed for one specific parameter, looking at the result and carrying the best value over to the profile. It is what most sets apart a correct print from a very good one.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Here we explain how it is done in PrusaSlicer. The complete procedures, the test models and the starting values for each case are in the <a href=\"https:\/\/labs.3dwork.io\/guias-impresion-3d\/calibracion_3d\" target=\"_blank\" rel=\"noopener\">3Dwork Labs FDM calibration guide<\/a>, which runs through the tests from basic to advanced.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">What PrusaSlicer calibrates today and what 3.x brings<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>PrusaSlicer 2.x does not ship with built-in calibration parts.<\/strong> The 3.x notes themselves acknowledge this: other slicers added them earlier and PrusaSlicer had fallen behind in this area. That does not stop you from calibrating: you load a test model and use the slicer&#8217;s tools to vary the parameter.<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li><strong>Change the value in the profile<\/strong> and print one version of the test for each value.<\/li><li><strong>Add G-code at a layer<\/strong> from the preview, to change a parameter from a certain height. It is the way to make a temperature tower.<\/li><li><strong>Height range modifier,<\/strong> which changes infill, layers and perimeters, speed or extrusion width settings between two heights. Temperature is not among them.<\/li><\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>The 3.x alpha adds built-in calibration<\/strong>: a flow tower and a temperature tower, in the plugins menu. You choose the test, adjust its parameters in a dialog and PrusaSlicer generates a project with the object and the configuration ready to slice. They are built as Lua plugins, with an API that Prusa describes as experimental. You will see it in the 3.x section, further down.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">How to run a test inside the slicer<\/h3>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/3dwork.io\/wp-content\/uploads\/2026\/10\/prusaslicer-anadir-codigo-g-capa.webp\" alt=\"PrusaSlicer preview with the layer slider and the orange icon menu open, showing the options to add a color change, pause and custom G-code\" title=\"- -\"><figcaption class=\"wp-element-caption\">In the preview, the icon next to the layer slider lets you add custom G-code at a layer (screenshot from an earlier 2.x version, English interface).

The code is applied before that layer and stays in effect until the next change. If the parameter cannot be changed this way, print several copies of the test, each with its own value.<\/li><li><strong>Note which value corresponds to each block<\/strong> before printing. It sounds obvious, but it is the most common mistake.<\/li><li><strong>Print, interpret and save.<\/strong> Pick the block that best meets what you are after, carry that value over to the profile (usually the filament one) and save it with a name of your own.<\/li><\/ol>\n\n\n\n<p class=\"wp-block-paragraph\">Prusa warns that custom G-code is a tool for advanced users: double-check what you insert, because some commands can overwrite printer values or drive the nozzle into the bed.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Flow test (extrusion multiplier)<\/h3>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/3dwork.io\/wp-content\/uploads\/2026\/10\/prusa-calibracion-flujo-sub-ok-sobre.webp\" alt=\"Three printed gray cubes showing underextrusion with gaps between lines, a correct result and overextrusion with excess material at the corner\" title=\"- -\"><figcaption class=\"wp-element-caption\">Underextrusion, correct result and overextrusion (labels in English).

In PrusaSlicer it is corrected with the <strong>Extrusion multiplier<\/strong>, on the Filament page of the filament profile. Prusa proposes two methods: a precise one, printing a cube in <strong>Spiral vase<\/strong> mode (Layers and perimeters) and measuring the wall thickness to calculate the value, and a visual one, observing the top layers.<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li><strong>What to look for:<\/strong> with underextrusion, gaps appear between the lines or between the perimeters; with overextrusion, excess material at the corners, more pronounced layers and uneven top surfaces.<\/li><li><strong>When to repeat it:<\/strong> with each filament type and color, because flow can change noticeably from one to another.<\/li><\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Temperature tower<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">A tower with blocks printed at different temperatures. In PrusaSlicer 2.x it is set up by adding, at the layer where each block starts, a G-code that changes the extruder temperature (the M104 command, according to Prusa&#8217;s help). The 3Dwork Labs guide explains another option: a script in the <strong>Before layer change G-code<\/strong> of the printer profile that changes the temperature according to the height.<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li><strong>What to look for:<\/strong> the finish of bridges and overhangs, the sharpness of the numbers and details, the stringing between the parts of the tower and the bonding between layers. To check layer bonding, the 3Dwork Labs guide suggests snapping each block.<\/li><li><strong>How to choose:<\/strong> the temperature that best balances all of the above. Then carry it over to the filament profile, for the first layer and for the rest.<\/li><\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Retraction test<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Retraction pulls the filament back during travel moves so it does not drip. In PrusaSlicer it lives in the printer profile (extruder page, Retraction section), and you can override it for a specific material in <strong>Filament Overrides<\/strong>. PrusaSlicer 2.x does not generate a retraction tower, so the usual approach is to print a stringing test model several times, changing the value between prints.<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li><strong>What to look for:<\/strong> the stringing between the parts of the test and the look of the seams.<\/li><li><strong>How to choose:<\/strong> there is no formula; each printer and extruder needs its own value, and it depends a lot on the filament. The 3Dwork Labs guide recommends leaving a margin of at least one step beyond the first value with no stringing.<\/li><li><strong>If it does not improve:<\/strong> before raising the retraction any further, check the filament&#8217;s moisture, the extruder and the cleanliness of the hotend.<\/li><\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">There are more tests worth doing once you have mastered these three: pressure advance (<em>linear advance<\/em> or <em>pressure advance<\/em>), input shaper, tolerances, overhangs and bridges. They are all explained in the <a href=\"https:\/\/labs.3dwork.io\/guias-impresion-3d\/calibracion_3d\" target=\"_blank\" rel=\"noopener\">3Dwork Labs FDM calibration guide<\/a>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Everyday features<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">Compatible with Marlin, Klipper and other firmware<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">In the Printers tab, the <strong>G-code flavor<\/strong> setting adapts the file to your machine&#8217;s firmware. PrusaSlicer 2.x offers, among others, Marlin 2, Marlin (legacy), Klipper, RepRapFirmware, Repetier, Smoothie, Sailfish, MakerWare, Teacup and Mach3\/LinuxCNC.

With Alt and the wheel you change the brush size, and the clipping plane helps you reach hidden areas.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Seam painting<\/h3>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/3dwork.io\/wp-content\/uploads\/2026\/10\/prusaslicer-pintado-costuras.webp\" alt=\"PrusaSlicer Seam painting tool panel with the enforce and block seam options, and brush size and shape\" title=\"- -\"><figcaption class=\"wp-element-caption\">Seam painting panel. Screenshot of PrusaSlicer, \u00a9 Prusa Research (help.prusa3d.com)<\/figcaption><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">The seam is the point where each perimeter starts and ends, and it usually leaves a small mark. With this tool (P key) you paint where you want to enforce it and where to block it, to hide it on an edge or on the back side. If you use the Aligned seam position, PrusaSlicer places it in the center of the painted area, which lets you draw clean seams.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Multimaterial painting<\/h3>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/3dwork.io\/wp-content\/uploads\/2026\/10\/prusaslicer-pintado-multimaterial.webp\" alt=\"PrusaSlicer multimaterial painting panel with first and second color assigned to extruders and the brush, smart fill, bucket fill and height range tools\" title=\"- -\"><figcaption class=\"wp-element-caption\">Multimaterial painting panel. Screenshot of PrusaSlicer, \u00a9 Prusa Research (help.prusa3d.com)<\/figcaption><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">If you have a multicolor printer, you assign colors by painting on the model (N key). Besides the brush you have <strong>smart fill<\/strong> (fills up to a marked edge), <strong>bucket fill<\/strong> (replaces an area of one color with another) and <strong>height range<\/strong> (paints between two heights). Each mouse button is assigned to a different extruder.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">ColorMix: more colors with the same filaments<\/h3>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/3dwork.io\/wp-content\/uploads\/2026\/10\/prusaslicer-colormix-extrusores-virtuales.webp\" alt=\"PrusaSlicer Virtual Extruders - Color Mixing window with several blends at 50, 25 and 75 percent and the layer sequence preview\" title=\"- -\"><figcaption class=\"wp-element-caption\">ColorMix virtual extruders window. Screenshot of PrusaSlicer, \u00a9 Prusa Research (help.prusa3d.com)<\/figcaption><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">ColorMix creates new shades by alternating, layer by layer, the filaments you already have loaded. At a normal distance, the eye blends the layers: 50% cyan and 50% yellow looks green. It is Prusa&#8217;s version of an idea that was born in the community (FullSpectrum), and its color-mixing model is published separately under the MIT license.<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>You need a multicolor printer: with an MMU, with several heads, with a tool changer such as INDX, or any other multi-filament system.<\/li><li>Below the filament selectors, the <strong>Virtual Extruders &#8211; Color Mixing<\/strong> button appears. There you choose ready-made blends or press <strong>Add blend<\/strong> to combine two or three filaments in the proportion you want.<\/li><li>Each blend is a <strong>virtual extruder<\/strong> that is used like a real one, including with the painting tools. In the dropdowns it is marked with [V].<\/li><li>Prusa gives 25\/75, 50\/50 and 75\/25 as tested proportions for two colors, and 33\/33\/33 for three, with layers of 0.15 mm at most and 5 to 10% gyroid infill.<\/li><li>To open a model with virtual extruders use <strong>File &gt; Open Project<\/strong>; if you import it, they are all merged into the last physical extruder.<\/li><\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The catch: there are many more tool changes, so more material is wasted than on a normal multicolor part. With a tool changer it is considerably more efficient than with a single-head system.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Tool change order<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">On printers with several extruders or heads, <strong>Print Settings &gt; Multiple Extruders &gt; Advanced<\/strong>, in the tool change order setting (<em>Orden de cambios<\/em> in the Spanish interface), decides how the changes are chained. You can minimize them, starting each layer with the tool the previous one ended with, or always repeat the same sequence on consecutive layers. The latter means more changes, but multicolor parts usually come out better because each layer has time to cool before printing on top of it.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">3MF projects<\/h3>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/3dwork.io\/wp-content\/uploads\/2026\/10\/prusaslicer-menu-archivo-guardar-proyecto.webp\" alt=\"PrusaSlicer File menu open with the Save Project as option highlighted\" title=\"- -\"><figcaption class=\"wp-element-caption\">File menu with Save Project as (English interface). Screenshot of PrusaSlicer, \u00a9 Prusa Research (help.prusa3d.com)<\/figcaption><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">With <strong>File &gt; Save Project as<\/strong> you save the objects, the configuration, the modifiers and their parameters in a single 3MF file. Prusa describes it as a complete snapshot: opening it on another computer should give the same G-code. It is the best habit you can adopt: save the project of everything you slice and you will be able to repeat or touch up a part months later without guessing which settings you used. For privacy, by default the 3MF does not store the full path of the original files.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Junction Deviation on Marlin 2<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">If your printer uses Marlin 2, in the printer profile you have <strong>Machine limits &gt; Maximum junction deviation<\/strong> (<code>machine_max_junction_deviation<\/code>). It turns on Junction Deviation, Marlin 2&#8217;s system for managing speed at corners: PrusaSlicer adds the M205 J command to the G-code and its estimator simulates this algorithm, so the estimated time matches the real one better. With the value at 0, the classic Jerk system is used. On the CORE One L it comes enabled by default.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">PrusaSlicer 3.x in alpha: what is coming<\/h2>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/3dwork.io\/wp-content\/uploads\/2026\/10\/prusaslicer-3-alpha-interfaz.webp\" alt=\"New PrusaSlicer 3.0 alpha interface in dark mode with the Slicing, Connect and Printables sidebar, the object list and the right-hand settings panel\" title=\"- -\"><figcaption class=\"wp-element-caption\">The new 3.x interface: sidebar, object list on the left and settings panel on the right. Screenshot of PrusaSlicer 3.0 (alpha), \u00a9 Prusa Research (blog.prusa3d.com)<\/figcaption><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">Prusa is preparing the biggest overhaul of the program in years: it has rewritten almost the entire interface and a good part of the internal architecture. The first public alpha came out on September 1, 2026 and the second on September 21. What 3.x brings:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li><strong>New interface,<\/strong> with a sidebar for Slicing, Connect and Printables, a right-hand panel that changes depending on what you select, favorite settings and a light mode.<\/li><li><strong>Multiple beds without the limit of nine<\/strong>, each with its own configuration and even with different printers, and <strong>several projects open<\/strong> in tabs.<\/li><li><strong>YAML profiles<\/strong> instead of .ini, which adapt to the real configuration of the machine, with filtering by filament type and fuzzy search.<\/li><li><strong>Built-in calibration<\/strong> (flow and temperature towers) through Lua plugins, with an API that Prusa describes as experimental.<\/li><li><strong>Offline mode:<\/strong> all online services can be disabled, and in fully offline mode the network libraries are not loaded.<\/li><li>It remains under the <strong>AGPLv3<\/strong> license.<\/li><\/ul>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/3dwork.io\/wp-content\/uploads\/2026\/10\/prusaslicer-3-alpha-varias-camas.webp\" alt=\"PrusaSlicer 3.0 alpha project with beds from three different printers, a Prusa MINI, a CORE One L and an XL, in the same scene\" title=\"- -\"><figcaption class=\"wp-element-caption\">Beds from three different printers in a single project.

Screenshot of PrusaSlicer 3.0 (alpha), \u00a9 Prusa Research (blog.prusa3d.com)<\/figcaption><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">But Prusa itself warns that this alpha is not for production: it is unstable, it does not have all the 2.x features and some will not arrive until 3.1.0. For now it only ships Prusa printer profiles (those of other brands will return later), resin slicing is disabled and, among other things, post-processing scripts, the custom G-code editor and screen reader compatibility are missing. It can be installed alongside 2.x without conflicts, but for printing, and above all if your printer is not a Prusa, stick with 2.x.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">PrusaSlicer, Bambu Studio and OrcaSlicer: which one fits you<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">PrusaSlicer is not alone. Today there are two other reference slicers, and all three share an origin: <strong>Bambu Studio<\/strong> is based on PrusaSlicer, and <strong>OrcaSlicer<\/strong> started out taking Bambu Studio and PrusaSlicer as its base and has grown with community contributions. That is why they are so similar in the way they work. None of them wins at everything: each one is designed for something different.<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li><strong>PrusaSlicer:<\/strong> the one that integrates best with Prusa printers (fine-tuned profiles, Prusa Connect and Printables), with very complete official documentation and more widely spaced stable releases. It works with printers from many other brands.<\/li><li><strong>Bambu Studio:<\/strong> a similar philosophy, but its strong point is the integration with Bambu Lab printers: remote control and monitoring, the AMS multicolor system and calibrations guided by the printer itself.<\/li><li><strong>OrcaSlicer:<\/strong> the most versatile. It is a project closely tied to the community, it collects profiles from a great many manufacturers and it ships the broadest set of calibration tests of the three.<\/li><\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Point-by-point comparison<\/h3>\n\n\n\n<figure class=\"wp-block-table\"><table><thead><tr><th>Criterion<\/th><th>PrusaSlicer<\/th><th>Bambu Studio<\/th><th>OrcaSlicer<\/th><\/tr><\/thead><tbody><tr><td>License<\/td><td>AGPLv3<\/td><td>AGPLv3 (Bambu Lab&#8217;s network plugin is optional and is not free software)<\/td><td>AGPLv3 (it can use the same optional plugin for Bambu Lab printers)<\/td><\/tr><tr><td>Platforms<\/td><td>Windows, macOS and Linux (Flathub)<\/td><td>Windows, macOS and Linux (AppImage and Flathub)<\/td><td>Windows (x64 and ARM64), macOS and Linux (Flathub and AppImage)<\/td><\/tr><tr><td>Integration with its own brand<\/td><td>Prusa printers: Prusa Connect, Printables and system profiles<\/td><td>Bambu Lab printers: remote control and monitoring, AMS and publishing to MakerWorld<\/td><td>It does not belong to any manufacturer<\/td><\/tr><tr><td>Profiles for other brands<\/td><td>More than 30 manufacturers in the profiles of its repository<\/td><td>11 manufacturers besides Bambu Lab in its repository<\/td><td>More than 60 manufacturers in its stable release<\/td><\/tr><tr><td>Network sending to other printers<\/td><td>OctoPrint, Klipper (Moonraker), PrusaLink, Duet and others<\/td><td>OctoPrint and PrusaLink<\/td><td>Klipper (Moonraker), OctoPrint and PrusaLink<\/td><\/tr><tr><td>Multicolor and multimaterial<\/td><td>Multimaterial painting and ColorMix (virtual extruders)<\/td><td>Color painting, AMS and mixed filaments<\/td><td>Color painting, per-feature filament and prime tower<\/td><\/tr><tr><td>Supports<\/td><td>Grid, snug and organic, plus paintable supports<\/td><td>Normal and tree supports (slim, strong, hybrid and organic), with custom supports<\/td><td>Normal and tree supports (slim, strong, hybrid and organic)<\/td><\/tr><tr><td>Calibration tests<\/td><td>Not built in on 2.x; the 3.x alpha adds flow and temperature towers<\/td><td>Guided calibrations with Bambu Lab printers; with other printers, temperature, flow, pressure advance, retraction, max flow rate and VFA<\/td><td>Temperature, max volumetric flow, pressure advance, flow, retraction, corners, input shaping, VFA, adaptive pressure advance and tolerances<\/td><\/tr><tr><td>Community (GitHub stars, 14 Oct 2026)<\/td><td>About 9,400<\/td><td>About 5,100<\/td><td>About 16,000, with a wiki open to contributions and an official Discord<\/td><\/tr><tr><td>Stable releases in 2026 (through 14 Oct)<\/td><td>2, plus two 3.x alphas<\/td><td>8, plus betas<\/td><td>4, plus nightly builds<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">The profile counts were made on the profiles included in each project&#8217;s repository and may change with each release; PrusaSlicer, in addition, updates its profiles online. Stars and the number of releases indicate activity, not quality.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">When to choose each one<\/h3>\n\n\n\n<ul class=\"wp-block-list\"><li><strong>You have a Prusa<\/strong> or you want a stable, well-documented slicer to get started: PrusaSlicer.<\/li><li><strong>You have a Bambu Lab<\/strong> and you want to make the most of the AMS, remote control and guided calibrations: Bambu Studio.<\/li><li><strong>You have a printer from another brand<\/strong> (Creality, Elegoo, Anycubic, a Voron&#8230;) or you like to fine-tune with calibration tests: OrcaSlicer is the most flexible option, although PrusaSlicer also covers it well if your model has a profile.<\/li><\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Nothing stops you from having all three installed: they all open STL and 3MF, and it is common to use one or another depending on the printer or the job.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Our verdict<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">After years of use, PrusaSlicer remains one of the slicers we recommend most, both for getting started and for those already squeezing the most out of their printer. It is free, open source, cross-platform, does not force you to create an account and has very complete official documentation. The view modes, with their color coding, let a beginner print without getting lost and an advanced user have full control.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">What to keep in mind:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>The sheer number of options is overwhelming if you do not start in Beginner mode.<\/li><li>The Spanish translation has stumbles that confuse, such as calling <em>brim<\/em> Balsa.<\/li><li>The multiple beds in 2.x have a limit of nine and share the same configuration.<\/li><li>The program is in the middle of a transition: the official help already marks 2.x as <em>Legacy<\/em>, but 3.x does not yet replace it for daily use.<\/li><\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Today, the version to print with is 2.x.
