Powder and Metrology Laboratory Team 
Powder sampling is a critical part of the AM process to ensure quality builds. After each sieve, a sample is sent to the in-house powder laboratory for viability of chemical, elemental, and gas parameters. Prior to each time powder is loaded into an AM machine, it is tested for conformance by Sintavia. Similarly, metallographic analysis is critical post-production. Sintavia’s in-house metallurgical laboratory is able to analyze specimens to understand the microstructure of each build. Sintavia’s metallurgical lab is ISO 17025/ANAB accredited. The laboratory teams have expertise from University of Pittsburgh, Purdue University, and Florida International University Advanced Materials Engineering Research Institute.
