Slicer software
Free programs such as Cura, PrusaSlicer and Bambu Studio that turn an STL file into instructions for your 3D printer.

What it is for
A 3D printer can't read an STL file directly. A slicer cuts the model into hundreds of thin layers and works out the path of the nozzle for each one. You choose the material, layer height, walls and infill, and the slicer saves a G-code file for your printer.
Slicers also do clever tricks that our lessons use: a colour change at a set height for two-colour parts, and spiral vase mode for thin, glowing lamp shades.
Most printer makers recommend their own free slicer. UltiMaker Cura and PrusaSlicer work with almost every printer.
Tips
- Load the STL and keep it in the orientation of the file: our parts are designed to lie that way.
- Use the preview to check the first layer and any overhangs before you press print.
- For a two-colour print, add a "pause" or "filament change" at the height given in the lesson.
- Spiral vase mode prints a single, thin wall: perfect for light cubes and shades.
