Repair STL files for 3D print

Only for Mac

Mac

Now with combine & auto-split, per-object color, image textures, and a smoother camera — plus tougher handling of damaged files. MeshForge is a Swiss Army knife for 3D-printable models. Drop in an STL or OBJ file, click Auto-Repair, and get a watertight, print-ready mesh — no 3D-modeling experience needed. FIX BROKEN MODELS • Auto-Repair welds split seams, closes holes, flips inside-out faces the right way, and removes floating debris — in one click • Repair many models at once: multi-select in a project, or batch-repair a whole folder of files without even importing them • The status bar always tells you, in plain English, whether your model is watertight and ready to print CHECK IT BEFORE YOU PRINT IT • Auto-orient finds the rotation that needs the least support material • Overhang view paints every surface that will need supports in red • Wall-thickness check finds spots too thin to survive printing • Stability check warns you if a model is likely to tip over mid-print • Live volume and weight estimates for PLA, PETG, ABS, resin, and TPU SHAPE IT • Plane cuts that keep the model solid — split big prints into printable halves • Smooth, simplify (reduce triangles), mirror, hollow, scale to exact size • Rotate, center, and drop to the print bed with one key DESIGN A PART THAT FITS Select any model and MeshForge builds a case, sleeve, or tray sized to fit around it — with printing clearance, wall thickness, and floor thickness you control. Perfect for holders, organizers, and protective cases for real objects. BUILT FOR THE MAC Native SwiftUI app with full keyboard shortcuts, drag-and-drop import, multiple windows for separate projects, and undo for everything. No account, no subscription, no internet connection required — your models never leave your Mac. Works with STL (binary and ASCII) and OBJ files; exports standard binary STL that any slicer accepts.

MeshForge 1.1 — the shaping & sharing update NEW • Combine: merge any selection of models into a single object (Cmd-J) • Auto-Split at Feature: MeshForge finds where a protruding shape meets the body and cuts there, giving you two clean, printable parts (Shift-Cmd-J) • Separate into Shells: break a combined model back into its pieces (Option-Cmd-J) • Color & Texture: give each model its own color, or drape a PNG/JPEG image over it — no unwrapping needed. Export with color via File > Export as OBJ • Move: position models anywhere on the bed from the Position & Size panel IMPROVED • All-new turntable camera: the ground stays level, you can't get lost under the bed, shift-drag slides the view, and double-click frames your models • Importing runs in the background with progress — no more waiting on big files FIXED • Damaged model files (with corrupt geometry) could freeze the app during import. They now import cleanly with bad triangles removed, or explain what's wrong.
