Standardization of 3D Printing

The Fraunhofer Institute for Laser Technology (ILT), Aachen, Germany, has received an award for decades of development in the field of Additive Manufacturing: The institute won a competition conducted by ASTM International and is now working on a project towards standardization of machine condition monitoring in laser beam powder bed fusion (LB-PBF). It is focusing on selecting and qualifying imaging sensor technology that can be used to specifically monitor the condition of LB-PBF systems. The institute will derive cost-reducing recommendations for end users from these data.
