PrusaSlicer

Concerned printers

PrusaSlicer is used with the available Prusa I3 MK3S+ and Prusa XL printers.

Slicer software

PrusaSlicer is based on Slic3r and enhances it with new controls, a more modern UI and dedicated profiles for the Prusa printers.

It supports multi-extruders, parts specific settings, and also SLA printers.

Basic usage

Setup

Upon opening the slicer, you are met with the following UI:

  1. Setup the basis pre-saved parameters here. In 99% of the cases, you do not need to modify specific settings:

    • Print settings: setups the layer height along with the printer axis speeds. Draft print can benefit from the 0.2mm Speed profile, while precise and small parts may prefer the 0.1mm Detail.
    • Filament: dictates the bed and extruder heat as long as fans speeds. Simply select default Prusa XXX profiles based on your material.
    • Printer: defines the bed size, available extruders with their size and mechanical data. It must corresponds to the actual printer the file is used on.

  2. To modify specific settings (mainly to modify the nozzle size), navigate the settings tabs and modify settings accordingly. Those are classified in three categories based on their impact: Simple, Advanced and Expert. Higher levels settings are shown only if you are in the correct mode. For this, on the upper right of the UI, select the desired mode.

    Warning

    Only tweak settings you understand the impact of !

  3. Set the support type, either none, only on buildplate (no support is generated if their base is on the part itself) and everywhere.

  4. Once imported, a part can be moved, rotated, scaled ... thanks to those tools.
  5. To import a file, simply drag and drop a .stl on the plate.
  6. Once everything set up, click on Slice now.
  7. When sliced, the layers view is shown. To modify the part, click on the left buttonto fall back to the object view.

Slicing

Once sliced, the part is ready to be saved and printed:

  1. The part is colored based on the layer type: infill, walls, supports, raft, skirt ...
  2. Estimated print times following each "print step" is given here. It may be helpful to optimize the print (rotating the part more, set less infill ...).
  3. The layers can be browsed by dragging the orange arrow up and down.

Once everything ok, click on the bottom right button to export the gcode and then print the file.

Session

The session can be saved and loaded as a 3mf file.
