Extract a 2D cross-section of any STL/OBJ/GLB at a specified Z height. SVG output. Useful for engineering drawings and laser cutting layouts.
Upload your model and choose a slice height (Z, in mm)
We intersect the mesh with the Z plane and extract the contour polylines
Download the cross-section as SVG — ready for laser cutting or technical drawings
0 bytes uploaded. Layer Slicer runs entirely in your browser using three.js and WebGL. Your meshes never leave your device.
Laser cutting templates, engineering drawings, technical illustrations, footprint extraction, and 2D CNC milling. The SVG units match the model's mm units.
Not yet. For now run the tool multiple times with different Z values. Multi-slice export is on the roadmap.
Yes. The slicer doesn't care about manifold-ness — it just intersects triangles with the plane. Open meshes produce open polylines.
Find walls thinner than your minimum print threshold. Ray-cast across the mesh to detect thin sections that may fail to print or break. Browser-based.
Open toolRender PNG previews of STL/OBJ/GLB files for galleries, README docs, and product pages. WebGL renderer, browser-based, no upload.
Open toolCompute the X/Y/Z bounding box of any STL, OBJ, or GLB mesh. Get exact print dimensions in mm — useful for fitting models to your printer bed.
