Made for 3D Printing
3D printing & additive: fix the mesh before you expect a first-time print
AI-generated or scanned meshes often have holes, non-manifold edges and debris — inspect, repair, scale and slice-preview in the browser.
Mesh inspection and repair run locally, models are not uploaded
Fix non-manifold, holes and floating shells; hollow, smooth and simplify
Scale, unit conversion and slice preview to rule out print failures
Pre-print repair
Diagnose and repair non-manifold, holes and debris into a sliceable mesh.
Server Mesh RepairCloudRepair meshes (fill holes, fix normals, remove degenerates) and convert formats on the server — suited for large models.Mesh DoctorLocalAnalyze meshes for holes, non-manifold edges, degenerate faces and watertightness; repair and export STL locally.3D Model AnalysisLocalAnalyze triangle count, vertices, bounding box, surface area and volume of STL/OBJ/PLY/3MF/GLB models in your browser.Model Print PrepLocalCenter on XY, drop to the bed and scale to a target height, then export STL — locally in your browser.
Scale and lighten
Unit scaling, simplification, smoothing and hollowing.
3D Print ScaleLocalScale STL/OBJ/PLY/3MF/GLB models and export STL, with mm/inch unit conversion. Runs locally in your browser.Mesh SimplifyLocalDecimate a mesh by a ratio to reduce file size and export STL, locally in your browser.Mesh SmoothLocalSmooth a mesh with Taubin (volume preserving) or Laplacian algorithm, adjustable iterations/strength and volume readout, export STL, locally in your browser.Mesh HollowLocalHollow a watertight mesh with a specified wall thickness, optional SLA drain holes, export STL, locally in your browser.
Slice and format
Slice preview, format conversion and viewing across STL/3MF/GLB.
Mesh SlicingLocalSlice STL/OBJ/GLB meshes by layer height, preview layer contours and export SVG / outline G-code. Runs locally in your browser.3D Format ConverterLocalConvert STL / OBJ / PLY / 3MF / GLB / GLTF to STL, OBJ or GLB in your browser. Nothing is uploaded.STEP to STLLocalConvert STEP 3D models to STL for 3D printing, fully in your browser. Nothing is uploaded.3D Model ViewerLocalView STL / OBJ / PLY / 3MF / GLB / GLTF 3D models: measure distance/angle, annotate, section, exploded view, screenshot, share. Rotate/zoom with auto-fit, runs locally.
Server-side repair for large meshes
Pro is $12/mo: 50 cloud tasks/day and 500 MB per file for very large or complex meshes; local repair stays free.
