摘要

Additive Manufacturing (AM) has the potential to revolutionize the way companies produce almost everything. This research discusses a new technique to qualify additively manufactured parts. A DMLS produced plate of 1 mm thick in Ti6Al4V (or Ti64) was subjected to microsample mechanical testing technique. It encompasses the determination of yield strength, ultimate tensile strength, elongation, and young's modulus. The microstructure and fracture surfaces were characterized as well. The local mechanical behavior was described in two different directions. The results have corroborated the scenario of a third industrial revolution, where an increase in strength over traditionally manufactured components was observed. Additionally, the orientation-dependent properties proved anisotropic behavior for AM parts and thus attested the aptitude of microscale testing to provide verifiable property data as inputs to global part performance and failure models.
