What do Customers Use our 3D Metrology Service For?

EDM Department's Optical 3D Metrology equipment gives our customers in-depth, non-contact metrology measurements of almost any shape, size and form. We also offer surface roughness inspection as well as 3D part scan to 3D CAD model overlays with difference modeling. Let EDM Department verify that every dimension on your part is within tolerance and specification with a simple, non-destructive, non-contact optical 3D part scan completed using variable focus technology.

Quality Assurance

  • Verify every dimension on your part is within tolerance
  • Measure surface form and roughness 

Part Scan to 3D CAD model

  • Reverse engineering
  • Original CAD model is insufficient and cannot support modifications or current manufacturing methods 
  • Explore new avenues to improve product performance and features
  • Original models and prints are lost or non-existant 

Difference Modeling

  • Compare physical piece part to design
  • Verify consistancy accross production parts
  • Confirm manufacturability of engineer's design

With the ability to access 100 million measurements on your most intricate part, we can verify your part and ensure that all services EDM performs are accurate and match your prints and tolerances. EDM is committed to quality and our 3D metrology equipment allows us to easily quantify and prove that. Companies interested in our 3D Metrology services often also explore our Wire EDM, Sinker EDM, and micro milling services as well. View all our capabilities:
