Slicer

Also known as: Slicing Software, Slicer Software

beginner General

Software that converts 3D models into G-code instructions the printer can understand.

A slicer is software that takes a 3D model (STL, 3MF) and converts it into G-code—the instructions your printer follows to create the object layer by layer.

How Slicing Works

  1. Load 3D model
  2. Configure settings (layer height, speed, temperature, etc.)
  3. Software “slices” model into horizontal layers
  4. Generates toolpath for each layer
  5. Exports G-code file
  6. Send to printer
