PrusaSlicer

PrusaSlicer takes 3D models (STL, OBJ, AMF) and converts them into G-code instructions for FFF printers or PNG layers for mSLA 3D printers. It's compatible with any modern printer based on the RepRap toolchain, including all those based on the Marlin, Prusa, Sprinter and Repetier firmware. It also works with Mach3, LinuxCNC and Machinekit controllers.

PrusaSlicer is based on Slic3r by Alessandro Ranellucci and the RepRap community.

Key features are:

• multi-platform (Linux/Mac/Win) and packaged as standalone-app with no dependencies required
• complete command-line interface to use it with no GUI
• multi-material (multiple extruders) object printing
• multiple G-code flavors supported (RepRap, Makerbot, Mach3, Machinekit etc.)
• ability to plate multiple objects having distinct print settings
• multithread processing
• STL auto-repair (tolerance for broken models)
• wide automated unit testing

Other major features are:

• combine infill every 'n' perimeters layer to speed up printing
• 3D preview (including multi-material files)
• multiple layer heights in a single print
• spiral vase mode for bumpless vases
• fine-grained configuration of speed, acceleration, extrusion width
• several infill patterns including honeycomb, spirals, Hilbert curves
• support material, raft, brim, skirt
• standby temperature and automatic wiping for multi-extruder printing
• customizable G-code macros and output filename with variable placeholders
• support for post-processing scripts
• cooling logic controlling fan speed and dynamic print speed
