MeshRefinery

MeshRefinery is an online toolkit that repairs broken 3D models for 3D printing and converts between file formats, with additional AI-powered generation from images. It focuses on fixing common errors in AI-generated or scanned models that cause slicer failures.

Yes, core features are free. File diagnosis, basic watertight repair, and format conversion run locally in your browser with no signup. Credits are only required for advanced 'Deep Repair' (which preserves colors) and the 'Image to 3D' generation tool.

No. For all free tools and diagnostics, processing is done entirely via WebAssembly in your browser tab. Your model data never leaves your computer, ensuring maximum privacy and security.

MeshRefinery supports STL, OBJ, GLB, glTF, and 3MF files for both repair and conversion. You can convert between any of these formats directly in the browser.

It is highly effective for common issues like non-manifold edges, small holes, and floating shells typical of AI output and scans. Extremely complex or corrupted files may have limitations, but the free diagnosis will show what it can fix.

AI 3D generators often produce meshes with invisible geometric flaws like open edges and internal debris. These look perfect visually but are not 'watertight,' causing them to fail in slicer software used for 3D printing.

Free repair makes the model watertight but may simplify geometry and drop vertex colors. Deep Repair (paid) does a more sophisticated surface reconstruction and can transfer approximate colors from GLB files into the repaired model.

No account is needed for the free tools, including diagnosis, basic repair, and format conversion. An account is only required if you purchase a credit plan for Deep Repair or Image-to-3D generation.

Credits are consumed for premium features: Deep Repair costs 20 credits per file, and Image to 3D generation costs 30 credits. Credits are purchased in packs or via subscription plans.

Yes, MeshRefinery offers annual subscription plans (Starter, Pro, Studio) that provide a monthly credit allowance for Deep Repair and generation at a discounted rate compared to one-time credit purchases.
