Mears Machine Delivers 1st Haynes 282 Additive Hardware for New Propulsion System

INDIANAPOLIS, Dec. 8, 2025 /PRNewswire/ -- Today Mears Machine Corporation (Indianapolis, Indiana) celebrates delivering a complete set of aerospace gas turbine hardware to a new customer.

The hardware includes two Haynes 282 components printed on the company's newly acquired Velo3D Sapphire XC machine, as well as Inco 718 printed hardware and other precision machined components manufactured by Mears Machine and other companies. The additive hardware went through a specialist combined Hot Isostatic Press (HIP) and Heat Treatment cycle to enable improved properties for high-speed rotating hardware, together with specialist polishing techniques to improved performance.

Many of the machined components required micron-level tolerances and were subsequently balanced to exceptionally stringent aerospace specifications—further underscoring Mears Machine's commitment to precision and technical excellence.

"Our team is incredibly proud of this achievement," said James Lloyd, CEO of Mears Machine Corporation. "This is a significant milestone for Mears Machine and our customer. The product is a fantastic feat of engineering, which has been realized by our world-class equipment and skilled employees. We wish our customer success with their testing and are excited by the growth prospects which appear to significantly exceed our existing print capacity. We also greatly appreciate the support of Velo3D, who since the purchase of our Haynes 282 machine back in April have provided fantastic support for both the machine and this product. "
