Indicator glass remodelling


  • Checking the sample provided by the client, looking for defects, damages, and deformations that need to be corrected when creating the new CAD model. When re-modelling old, used parts, a comprehensive examination of the samples to list the defects that have developed over time and use is crucial.
  • Since the geometry of the glass features no fixed measuring points, the exact dimensions can only be obtained by scanning. Preparing the sample for scanning.
  • The shiny surfaces are treated with a matte, so-called scanner spray, which coats the sample surfaces with a white powder 1-2 microns thick, eliminating glaring and providing for successful scanning.
  • The scanning creates so-called point clouds, which are used to create the mesh.
  • Preparation of a CAD model taking into account the specifications of the selected production process. In this case, the remanufacturing will be done using a 3D resin printing process.
  • Comparison of the finished CAD model with the scanned mesh.

The sample part shows clearly deformation during use, with different measurement results:

The new CAD model of the part has been created using the Shapr 3D CAD software:
