For years, the 3D printing industry was held back by the simple fact that print outcomes are not predictable or consistent. Mechanical properties are determined by many factors, and those factors raise questions about how additive manufacturing solutions can ensure quality. What are the equipment conditions at the start of the print? What are engineering process margins during the print? And what will be the impact on the mechanical properties or dimensional accuracy? Given these historical uncertainties, moving parts to manufacturing using additive is traditionally an extremely difficult and lengthy process. Verifying the parts and generating a certificate of conformance is tedious and expensive. Today, pre-build auto-testing of calibration and compliance as well as in-situ monitoring of the build quality now provides the capability to ensure appropriate build quality and correlation with mechanical part properties in volume production.
