SLA Slice Preview
Slice an STL, OBJ or PLY model into SLA cure masks and scrub the filled cross-sections — a preview, not a printable file. Runs entirely in your browser.

How to use
- Drop a 3D model in, or tap the box to choose one. STL, OBJ and PLY all work, and everything stays on your device.
- Set the layer height in millimetres (resin printers often use 0.05 mm), then press Slice. The 3D engine loads once on first use.
- Drag the Layer slider to scrub up and down through the model. Each layer shows the solid cure mask — the white area a resin printer would expose at that height, with holes cut out.
FAQ
Can I print from this tool?
No — this previews how the model slices into layers — it is NOT a printable file. Real printing needs a full slicer — your resin printer’s software (such as Lychee, CHITUBOX or your printer’s own app) — to add supports and generate the sliced file the printer reads.
What is the cure-mask view?
For SLA and resin printing, each layer is a solid shape the printer’s light source cures all at once. This view fills the model’s cross-section in white on a dark background, with internal holes cut out, so you can see exactly what would be exposed at each height.
Is my model uploaded anywhere?
No. The file is read, parsed and sliced entirely in your browser. It never leaves your device, so the tool works offline and stays private. The 3D engine loads once on first use and is then cached.
