Layerpaint paints per-triangle colors on STL, OBJ, and 3MF meshes — then exports a Standard 3MF your slicer already understands. No install, no upload, no subscription.
Works in Chrome, Edge, Firefox, Safari · Your model never leaves your browser
Auto-partitions the mesh along creases, so a helmet, a gem, or a belt becomes a single clickable region. No brushing required.
Adjustable radius, depth control, snap-to-crease. Paint fine detail without spilling onto the next part.
Fill connected flat regions in one click. Stops at creases automatically — great for broad panels and large surfaces.
Paint one side, get the other for free. Perfect for characters, vehicles, and symmetric props.
Scrub through print layers before you slice. Catch color placement issues at print height, not at the printer.
Exports the Materials Extension every major slicer reads — Bambu Studio, OrcaSlicer, PrusaSlicer. Drop it in and slice.
Pick from the Bambu, Polymaker, Prusament, Overture, Sunlu, eSUN, Elegoo, and Creality libraries — match what's actually in your spool rack.
Your mesh never leaves your browser. No account required to try, no upload, no tracking of your files. Open the DevTools Network tab and check.
Drag an STL, OBJ, or 3MF onto the canvas. Layerpaint welds duplicate vertices and detects creases automatically.
Choose up to 16 filaments from the library, or enter hex codes. Colors mirror what your slicer supports.
Click regions, brush detail, wand large panels. Mirror for symmetry. Undo at any time.
Drop the file into Bambu Studio, Orca, or Prusa. Colors come through on the first try.
Paint and preview free. Pay once to unlock export forever.
Yes. Export a Standard 3MF and drop it in. Bambu Studio's "Standard 3MF Color Parsing" dialog picks up the colors automatically. Same file works in OrcaSlicer and PrusaSlicer.
No. Everything runs in your browser. Your STL/OBJ/3MF never touches a server. Check the Network tab if you like.
Meshes up to several hundred thousand triangles work smoothly on a modern laptop. Larger models still work, just slower.
Yes. Save to a .layerpaint project file (mesh + paint state, gzipped). Reload it any time, from any machine.
No. The painter is free to use without signing up. You only need an account to unlock export — pay once, log in on any device.
Log in with the email and password you set at checkout. Your export unlock follows your account, not the browser.
The full painter is free to try before you buy. If the export still doesn't work for you, email us within 14 days.
