PrusaSlicer

Updated 1 month ago ​by Martin Lexa

Your 3D printer can print almost anything if you prepare the model the right way. Whether you downloaded 3D models from the Internet or created your own from scratch, you will need to convert the .obj or .stl format into a .gcode file. Gcode is a file format readable by 3D printers. The file contains information about nozzle movement and the amount of filament to extrude.

Prusa Control is not being developed anymore and is now obsolete. We do not recommend to use it anymore.The easy and streamlined user interface, as well as the colorprint feature have been transferred to the latest version of PrusaSlicer where you can choose between 3 levels of interface complexity.

How to operate PrusaSlicer

PrusaSlicer will allow you to tweak a wide range of print settings. This is useful when you want to set up your own custom-made presets. For example, you can save presets for supports, brims or even different kinds of infills, so you have them ready at any time. H

  1. Material selection
  2. Printer selection
  3. Right-clicking the model opens a context menu with Rotate, Resize and other options
  4. Change the preview type
  5. Model preview
Please note that printing with 0.05 layer height is very difficult, it is recommended only to experienced users. The extruder has to be perfectly assembled, calibrated and maintained.

Printing with support material 

As you proceed towards printing more complex objects, you will probably need to take some extra steps in order to print them in full quality.

If you print an object with an overhang beyond 45°, it can start sagging during the printing process. To avoid that, you need to add supports, essentially a scaffolding designed to hold the problematic parts of the object in place. When the print is finished, you can remove the extra material. PrusaSlicer has a built-in function that can generate the supports automatically.

Here is a simple guide how to use the support function:

  1. Go to the Print settings tab.
  2. Select the Support material menu.
  3. Check the Generate support material box.
  4. Overhang threshold lets you set an angle, at which supports should be created. Setting this item to zero lets the printer detect problematic parts automatically and print supports where needed.
  5. Enforce support for the first layer is used mostly with small models or models with a small base to prevent the object from breaking or tearing out from the bed.
