STL Workshop

STL Workshop is a 3D model viewer and editor built for 3D printing.

IMPORT • STL (binary, ASCII, colors), OBJ, PLY, 3MF, USDZ • From Files, Mail, AirDrop — open any model in seconds

VIEW • 7 render modes: shaded, edges, wireframe, x-ray, normals, overhangs, wall thickness • Interactive section cut, layer preview, exploded view • Studio and HDR lighting, realistic materials

ANALYZE • Full diagnostics: watertightness, manifold topology, normals, shells • Dimensions, volume, surface, weight and cost by material and infill • Estimated print time, bed stability, center of gravity • Precise measurements: distance, angle, diameter

PREPARE • Automatic repair: filled holes, fixed normals, removed debris • Auto-orientation minimizing overhangs on import • Scale, rotate, mirror, lay flat, automatic base • Hollowing with drain holes (resin), drilling and booleans, embossed or engraved 3D text • Grid duplication, predefined printer beds

EXPORT • STL, OBJ, USDZ and augmented reality (AR Quick Look) • HD transparent captures, 360° GIF • Direct upload to OctoPrint or WebDAV servers • Siri Shortcuts: convert to USDZ, repair an STL

Units in millimeters. No ads, no data collection.
