There can be several things causing Lychee Slicer to crash at slicing:

Computer configuration:

Remember that these recommendations are for 2K and 4K printers and that with higher resolution printers, you will need a more powerful computer.

Printer and settings:

  • As mentioned previously, the resolution of your 3D printer is important for the slicing stage. Depending on the size of your model/project you can change the settings to optimise slicing depending on the screen resolution.
  • The same thing goes with Anti-Aliasing. The higher the AA levels, the more power Lychee Slicer will need. Not all 3D printing projects need Anti-Aliasing and you can slice without it and still get great results if your printer has a high resolution.

Project file:

  • Another reason Lychee Slicer might crash at slicing is if the model needs repairing. You can see a model is broken in Lychee Slicer when it appears red instead of blue. You can use the Repair Tool or a 3D design program to repair the file before slicing.
  • If your model has an abnormally high polygon count, Lychee Slicer could struggle at the slicing stage. Try with a lighter file/model to double-check that you are able to slice.
