The repair process automatically fixes common printing issues — holes, thin walls, non-printable geometry — and optimizes your model for your printer.

Set the scale

Choose how to size your model:

Repair quality is now set automatically — every repair runs at maximum detail, and medical DICOM scans use an optimized resolution. When the repair completes, you’re taken to the repair detail page where you can view the fix report, compare before and after, and download your print-ready model.
Not sure which preset to use? Start with Custom — it works well for most models. You can always re-repair with different settings.
Your first 2 repairs are free. After that, you need a subscription to continue repairing. See Plans and pricing.
