PrintSlice cuts oversized STL files into pieces your printer can actually hold, then engineers the connectors that pull them back together after printing.
Every cut, measurement, and connector placement happens live in the viewport — no export, no guesswork, no waiting on a server.
Any STL, any size — dragged straight into the browser and read on the spot.
Tell PrintSlice your bed dimensions — it finds the cuts that make everything fit.
Matching connectors print right into the seams, so assembly is just pressing pieces home.
Each seam gets a tab and a socket cut from the same geometry, with clearance dialed in automatically — no filing, no glue, no guesswork.
Binary or ASCII STL, simple or dense — parsed locally the moment you drop it in.
Set your build volume once — every cut respects it automatically.
Connectors come from the model's own geometry, not a generic bolt-on shape.
The split, the joints, the preview — computed client-side, always.
Kept fast even as triangle counts climb.
Parts line up on the first try — no post-processing required.
Every feature, every connector type, no upsells.
A browser-based tool that splits oversized STL models into bed-sized pieces and generates matching connectors so they assemble back into the original shape.
STL files, both binary and ASCII, for input — and binary STL for the split output pieces, the standard format every slicer accepts.
You set your printer's bed size and a safety margin; PrintSlice computes watertight cuts through the model so every resulting piece fits within that volume.
Every connector pair — the tab and its matching socket — is generated from one shared definition using real solid geometry, with a small configurable clearance built in.
Yes — the exported pieces are standard STL files, compatible with any slicer or printer you already use.
No. Splitting, connector generation, and the 3D preview all run in your browser — nothing to install, and your model never leaves your computer.

Model at whatever scale the idea needs — PrintSlice figures out how to print it.
