3D scanning and reverse engineering · Twin Cities, Minnesota

Have the part but not the file? Get the file.

Send the physical part, or your scan data, and get back clean parametric CAD with real features, not a mesh. Then modify it, print it, mold it, or hand a drawing to a machine shop. Replacement parts, obsolete parts, improved parts.

Why a real model, not a scan

A scan is a photograph. CAD is a drawing you can change.

A raw scan is millions of triangles: it looks right, it prints once, and you cannot edit it, dimension it or send it to a molder. Reverse engineering rebuilds the part as proper geometry, with the holes round, the walls flat, the fillets real and the dimensions where the designer meant them. That is the file you can keep using.

1

Replacement parts

The clip that broke, the bracket nobody sells any more, the housing for a machine whose maker is gone. Rebuilt, improved if you want, and printed or quoted for molding.

2

Your own legacy parts

Parts you make or sell but only have samples or paper drawings for. Turned into CAD so the next run, the next supplier and the next revision all start from a file.

3

Improved parts

While the model is open: thicker where it broke, a better snap, a mounting boss that was always missing. Reverse engineering is the cheapest moment to fix a design.

What you get

Editable CAD, checked against the original.

Deliverables

  • Parametric CAD with real features, native plus STEP.
  • Print-ready STL, and a printed check part when fit matters.
  • A PDF drawing of the critical dimensions, for a machine shop or a molder.
  • A deviation note: where the model differs from the sample and why (worn, warped, or improved on purpose).
  • Your original back, unharmed. Parts are measured, not sacrificed.
  1. Send the part or the dataThe physical part by mail or drop-off in the Twin Cities, or your existing scan (STL, OBJ, PLY), photos and any drawings.
  2. CaptureMeasured and scanned as the geometry requires. Wear and damage noted so they are not copied into the new part.
  3. ModelRebuilt as clean parametric CAD: true circles, flat faces, real fillets, sensible dimensions and tolerances.
  4. Fit checkCompared against the original, and where it matters, a printed part is tried in place.
  5. DeliverFiles, drawing, deviation note, and the original part returned.

Replacing a part on equipment you own is fine. Reproducing someone else's protected product to sell is not, and I will say so rather than take the job.

FAQ

Reverse-engineering questions.

Do I have to send the part?

Usually yes; measurement and a fit check need it in hand. If you already have a good scan, send that with photos and a couple of hand measurements instead.

Will the new part be exact?

It will be what the original was meant to be. Worn, warped or broken features are rebuilt to their intended geometry, and the deviation note tells you what was changed.

Can you improve it while you are at it?

Yes, and that is the best time. Say what failed or what you wish it had, and it goes into the brief.

Can you then make it?

Yes: printed in FDM or SLA, or designed for molding if you need quantity. Or take the files anywhere.

What about my part's safety?

Parts are measured, not destroyed, and returned with the files. If a part is irreplaceable, say so and it is handled that way.
