Main features
FREE AND OPEN-SOURCE
PrusaSlicer is based on Slic3r by Alessandro Ranellucci. It's completely free and open-source. Thanks to the strong community and core team of developers in Prusa Research we can continually add new functionality. You can follow the development process on Github.
CLEAR & SIMPLE UI
Slic3r was always known to be powerful and versatile, but some features were difficult to use, if not outright hidden behind obscure menus and dialogs. Our goal with the reworked UI was to expose all the power features while making the UI clear and simple to use at the same time.
CUSTOM SUPPORTS
PrusaSlicer lets you create support blockers and enforcers. Support blockers are useful when you’re generally happy with the automatic supports, but you want to exclude some areas. With support enforcers, you can turn automatic supports off and select specific parts which need supports.
MSLA & MULTI MATERIAL SUPPORT
With the release of our Original Prusa SL1 resin 3D printer, we’ve added masked SLA (MSLA) mode into PrusaSlicer. As far as we know, PrusaSlicer is the first high-quality open-source MSLA slicer available. PrusaSlicer also supports multi material FFF printing with the Original Prusa MMU2S.
AUTO-UPDATING PROFILES
Testers and developers at Prusa Research are constantly working on presets for 60+ filaments and resins. We are adding profiles on regular basis, following materials by the most popular manufacturers. You will get new profiles automatically through auto-update function.
SMOOTH VARIABLE LAYER HEIGHT
3D printing is always about the quality versus the print time. In PrusaSlicer, you can select the layer height for each part of the object separately. Our software takes care of smoothing so the final print looks best as it can and the printing time remains acceptable. Check out the video.
FIRMWARE FLASHER
PrusaSlicer includes built-in firmware flasher for Original Prusa i3 printers. You can just connect your printer to computer via USB cable and easily flash the firmware via PrusaSlicer. Don't forget to upgrade your printer regularly! 😉
COLOR CHANGE
You can prepare prints with color change directly in PrusaSlicer. Just insert the “pause for filament change” code at layers which you marked in the print preview screen. A preview is displayed instantly so you’ll see exactly how your model will look with color-change.
OCTOPRINT INTEGRATION
With Octoprint application, you can control your printer via web browser. PrusaSlicer is now supporting advanced features of Octoprint like upload queue or Cancelobject plugin, which allows you to cancel printing of one particular object on the print bed.
