System for identifying parts formed in an additive manufacturing build

Abstract:

A system and method for identifying test bars formed during a selective laser sintering build. A part cake is formed during a selective laser sintering build. The part cake comprises parts formed from a powder by selective laser sintering and unsintered powder around the formed parts. The parts include test bars for performing material testing. Each test bar includes a plurality of indentations in a first grip section and a second grip section. The plurality of indentations are arranged in a information providing pattern that is adapted to be readable after the test part is removed from the part cake.
