splicestl vs. the slicers’ cut tools
Cura, Bambu Studio, OrcaSlicer, PrusaSlicer and Meshmixer, feature by feature
The slicers can cut a model along one plane, and the three PrusaSlicer-family slicers (PrusaSlicer, Bambu Studio, OrcaSlicer) also offer alignment connectors and a dovetail joint on that plane. That covers "cut it in half". It does not cover a model that needs cuts on two or three axes, an automatic fit to your build volume, structural joinery beyond a dovetail, or an interlocking cut surface. Checked against each vendor's documentation, October 2026.

If you used Meshmixer to split models: Autodesk stopped developing it in September 2021 and no longer supports it; the last release dates from 2018. splicestl reproduces its plane-cut + connector workflow in a browser. The Meshmixer alternatives guide covers its other workflows.
Hands-on with one test model: STL splitter comparison. The paid desktop splitters: Split3r, LuBan.
