Short answer

MetroX is the strongest catalog fit for detailed mechanical parts, while CR-Scan Otter covers a wider object-size range. 3DMakerpro Fox lowers the entry price, but its NIR workflow and 0.10 mm stated resolution suit less demanding reconstruction work.

Start with the smallest critical feature

Published accuracy and resolution are best-case manufacturer figures. Identify the smallest edge, hole or mating surface your CAD model must retain, then test that feature on your own representative part.

Plan the mesh-to-CAD work

A scanner creates a point cloud or mesh, not a finished parametric model. Budget for alignment, cleanup, surface reconstruction and dimensional checks in your preferred CAD workflow.

The shortlist compares capture technology, stated accuracy, export formats and independent workflow reports. Manufacturer accuracy figures are not laboratory results.

  • Mechanical and reflective parts often need markers or scanning spray.
  • Large textured parts reward tracking range more than headline resolution.
  • Use calipers or a known reference to verify critical dimensions.
