measuring 3D Printed Parts

The first concern in calibrating a 3D printer is making sure that offset layers are smooth and transition-free. A sloped side with a terraced look is inferior.

A second concern is the presence of voids and sprue on edges and surfaces.

Quantifying your three-d printed part’s surface is the way to establish and  maintain quality over time. 

On parts, whether plastic or metal, or nearly any other material, you can measure surface parameters and surface shape  features like:

  • Radius of curvature
  • Cracks, pits and dings
  • Stair-stepping and terracing
  • Chamfer and edge-break
  • Surface texture
  • Striations and linearity

Video tutorial

Video: Measure Radius of Curvature

This six-and-a-half minute video demonstrates how to take a measurement and get the Radius of Curvature profiles you need from it. You can see more tutorials on our Training Video Page.

App Note: Compare Measurement to CAD

This 4D InSpec application note shows a simple example of exporting a 3D measurement from 4D InSpec as .XYZ, then importing that and the CAD file for the part surface in a third-party software package, comparing the measured part to the designed CAD model.

You can find more application notes on our Support Applications Page.
