Browser CAD, then PrusaSlicer.
PrusaSlicer treats imported 3MF parts as first-class “modifier” meshes — ForgeSlicer's exporter targets exactly that format. Build with primitives + Booleans, export 3MF, and PrusaSlicer's per-part settings dialog already understands your positives and negatives.
ForgeSlicer's 3MF export tags each Negative as a Cut modifier. PrusaSlicer's import already knows what to do — no manual mesh-by-mesh classification.
Group structure carries across, so PrusaSlicer's per-object settings dialog lets you tune supports, infill, or layer height per part without re-grouping.
ForgeSlicer's voice editing + AI mesh generation (via Meshy.ai — third-party AI integrated into the workflow) gives PrusaSlicer users a modern modelling layer to feed their slicer.
Pre-loaded profiles for the MK4S, MINI+, XL, CORE One — the bed-fit checker matches PrusaSlicer's plate dimensions so what fits in CAD fits in slicing.

Primitives + Booleans + voice. Negatives become PrusaSlicer modifier-cuts on export.
- 3Hand off
Export 3MF, drag onto PrusaSlicer, fine-tune per-part settings, slice and print.
The workspace is free, runs in your browser, and ships with 12 beginner starter templates so you don't face a blank canvas.
