Slic3r

Slic3r helps people prepare digital models for 3D printing. It accepts STL, OBJ and AMF files and produces instructions for a printer. Users can set up a print, inspect its layers and toolpaths, and adjust options such as infill, layer height and supports. The program can handle individual print jobs or repeated work with several models.

Adjust print settings and generate G-code from common 3D model files in one workflow.

The software divides a model into layers, plans the paths the print head follows and estimates the material needed. It exports G-code and can save layer outlines as SVG files. A graphical interface handles print setup, while command-line controls support scripted jobs. Additional tools can repair mesh geometry, split a model into parts and send jobs to connected printers.

Features:

• Import STL, OBJ and AMF models
• Generate G-code for FFF and FDM printers
• Preview layers and planned print paths
• Adjust infill, supports and layer height
• Repair meshes and divide models into parts
• Run slicing jobs from the command line
