  • Our tips

    Lychee Slicer relies heavily on the graphics card in your computer; consequently, some laptops with shared memory rather than dedicated GPU memory, may encounter some slow down. In these cases slowdown may be noticed during the final slicing process.

    Please keep in mind that preparing very high polygon count 3D models (large file sizes) can reduce the speed of the application. Depending on the scale of your model, these files can be a wasted use of resources for your computer and 3D Printer.

    For example, a 100+ Mb STL file of a 28mm miniature is often a waste of memory/processing power as the microscopic detail and huge resolution from millions of extra polygons will not be reproduced by even the best 3D printers at that scale.
