Slicer Software Overview

A slicer converts your STL or 3MF file into the G-code that your printer understands.

What a Slicer Does

The slicer disassembles the 3D model into horizontal layers and plans the print paths for each layer: outer walls, infill, supports, bridges, transitions. From these paths, G-code is generated – a list of machine commands (position, speed, temperature) that the printer executes.

The Most Important Slicers

PrusaSlicer (free, open source)

A mature, well-balanced slicer from Prusa Research. Very good default profiles, sophisticated support algorithms, broad printer support. The basis for many other slicers.

OrcaSlicer (free, open source)

A fork of Bambu Studio, which in turn is based on PrusaSlicer. Very actively developed, many built-in calibration tools (Flow Rate, Pressure Advance, Temp Tower). Popular among Voron users and for anything that requires tuning.

Cura (free, open source)

From Ultimaker. Long the standard in the hobby sector, huge selection of printer profiles, many plugins. Compared directly to PrusaSlicer/Orca, somewhat less delicate with default profiles, but very accessible.

Bambu Studio (free)

Optimized for Bambu Lab printers (X1, P1, A1). Excellent profiles, cloud workflow, AMS multi-material support. Less useful for non-Bambu printers.

SuperSlicer (free, open source)

Another PrusaSlicer fork with an exceptional number of detailed settings. More for power users who want to tweak every screw.

Which Slicer is Right for You?

Before Slicing: Check Your File

Before slicing, briefly load your model into the STL Viewer. Are the dimensions plausible? Does the mesh look complete? For issues, see Repair STL.
