After printing various parts with AF-9628 powder, Capt. Erin Hager analyzed the resulting porosity, strength and impact toughness. She noted that the mechanical properties were quite good. She “didn’t see cracking,” and asserts that, [the output] was very similar [to traditionally manufactured parts]. In fact, the parts “matched the required 10 percent elongation, indicating increased strength without becoming brittle,” and “met or exceeded [specifications] straight out of the machine.” (Courtesy photo/Air Force Institute of Technology)
