3D Scanning Services

NeoMetrix offers high accuracy 3D scanning services for reverse engineering and computer aided inspection applications.

3D scanning refers to the rapid capture of data in order to define complex shapes utilizing optical technology.  The 3D scanner employs some type of optical projection, either laser or structured light, and one or more cameras.  The cameras detect pixels along the projected stripes in order to triangulate data points along each stripe.

The output from this process is called a “cloud of points”. Some objects may be scanned from multiple positions and orientations to ensure complete coverage.   Point clouds can then be triangulated into a polygon mesh, or STL file.  A complete, or watertight STL is suitable for 3D printing.  Further processing may be required to develop a 3D solid model for reverse engineering, or compared to the original design for computer aided inspection.

NeoMetrix offers 3D scanning services utilizing a variety of equipment and our engineers will consult with the client to determine the best tool for each project.

Reverse Engineering Services

3D scanning is generally the first step in reverse engineering complex parts. The ultimate goal of reverse engineering is generally to create a 3D CAD (Computer Aided Design) model for use in the customer’s design system.  There are several types of models that can be generated from 3D scanned data. These include:

• Parametric Solid Model

  • File Format: Solidworks (sldprt)

• Feature Based Solid Model

  • File Format: iges, step, parasolid, Solidworks (sldprt)

• Rapid Surface Model

  • File Format: iges, step, parasolid, Solidworks

• Hybrid Solid
  • File Format: iges, step, parasolid, Solidworks (sldprt)
• Polygon Mesh

  • File Format:  STL, OBJ, VRML, PLY
