In extensive evaluations, INDO-MIM Inc achieved sintered parts with density levels exceeding 98% of theoretical, with consistent hardness values (74–79 HR15N) and tightly controlled carbon content (0.013–0.014%) across multiple sinter runs. These results confirm that OptiPowder Ni718 meets the rigorous performance standards required for its customers’ applications.
“Qualifying Ni718 on the HP Metal Jet S100 is a major step forward for binder jet adoption in high-performance industries,” said Jag Holla, Sr. VP Marketing, INDO-MIM Additive Technologies. “This milestone demonstrates INDO-MIM’s commitment to advancing binder jetting into production and enabling our customers to benefit from scalable, cost-effective solutions for superalloy components.”
Metallographic analysis confirmed OptiPowder Ni718 exhibited the powder quality required for denser parts in binder jet printing enabling the expected gamma phase microstructure critical to Ni718’s high-temperature strength and oxidation resistance.
“This qualification is an important milestone not just for INDO-MIM, but for the wider adoption of binder jetting,” said Dr. Mukund Nagaraj, “By combining our production expertise with Continuum’s US-based environmentally friendly powders, we’re demonstrating that binder jet can deliver complex, high-value components with the consistency and performance our customers demand.”
“Achieving this milestone with INDO-MIM on a HP Metal Jet S100 system represents a breakthrough for binder jet adoption in aerospace, defense, and energy,” said Rob Higby, CEO of Continuum Powders.
Our OptiPowder line is designed for high repeatability and performance, and this qualification demonstrates its readiness for the most demanding applications while achieving significant positive environmental impact and securing US sourcing for powder and parts.”
