Researchers in California at the Lawrence Livermore National Laboratory have been studying the effects of residual stress on 3D printing, analyzing it through photos of 3D printed products and examining points of stress, as well as coming up with ideas on how to prevent residual stress from distorting 3D printed products in adjusting settings and parameters. The Accelerated Certification of Additively Manufactured Metals Strategic Initiative uses destructive analysis combined with digital image correlation.
