General-purpose handheld scanner
Useful for textured objects and a range of part sizes when portability matters.
3D scanning · process guide
Replicas and replacement parts
Capture an existing object as the first step toward repair, reverse engineering or a remade component.
What the process does
From an idea to a repeatable workflow.
A 3D scanner captures a point cloud or mesh. That data can preserve organic surfaces and dimensions, but it is not automatically an editable, production-ready CAD model.
Reverse engineering usually adds alignment, mesh cleanup, surface or feature reconstruction, dimensional checks and design changes for the chosen manufacturing process.

The workflow
How the process works
Workflow reviewed 07 Oct 2026
- 01
Define the needed accuracy
Identify critical mating surfaces and measure them separately where necessary. Published scanner figures are not a result for your part.
- 02
Prepare the object
Clean the surface and add markers or removable scanning spray when required by the scanner and material.
- 03
Capture overlapping views
Move steadily, keep tracking and collect enough coverage for alignment while avoiding inaccessible geometry.
- 04
Clean and align the mesh
Remove background data, align passes, fill only appropriate gaps and inspect for tracking errors.
- 05
Rebuild and validate
Use the mesh as reference for CAD, then compare critical dimensions before printing or machining a replacement.
Choose the setup
What machines and tools do you need?
Metrology-oriented scanner mode
Better aligned with small mechanical details, markers and controlled capture—not a substitute for dimensional verification.
Mesh and CAD software
Needed for cleanup and reconstruction; confirm export formats and computer requirements before buying.
Before you start
Workshop checklist
- Critical dimensions identified
- Surface-preparation method
- Markers or turntable if required
- Compatible computer and exports
- CAD reconstruction plan
For makers selling online
Make the workflow repeatable before listing the result.
A good product page starts after the first successful sample: test the exact material, record the setup and leave room for inspection and finishing.
- 01
Describe the result as a reconstruction workflow, not an automatic duplicate.
- 02
Measure critical interfaces independently before promising fit.
- 03
Agree image rights and the intended use of reference objects before sharing a case study.
