Slicers (3D Printing)
Slicers convert 3D models into printer instructions, cutting the mesh into layers and generating the toolpaths, supports and temperatures a 3D printer executes. They sit between modeling and the physical print, and slicer settings influence print quality at least as much as the printer itself.

Slicers (3D Printing): frequently asked questions
What does a slicer actually do?
It converts a solid 3D model into G-code, the layer by layer movement and extrusion instructions a printer follows. That includes wall thickness, infill patterns, support structures, print speed and temperature control.
Are slicers free?
The mainstream FDM slicers are free and mostly open source, and printer manufacturers often ship customised versions of them. Paid options exist mainly for industrial machines and advanced process control.
What file formats do slicers accept?
STL is the traditional input, 3MF is the modern replacement that also stores settings and colors, and most slicers also read OBJ. Slicers output G-code or a vendor specific variant of it.
