BMT Pinion
Carpenter Technology has worked with BMT Aerospace’s additive manufacturing (AM) subsidiary to produce a 3D printed aerospace pinion using a custom material.
BMT Additive, a supplier of metal 3D printed parts, initiated the project to redesign the pinion using AM in order to maximise the performance of the part, with a view to expanding production with 3D printing across other applications.
The pinion was printed by Carpenter Additive, a recently developed subsidiary, using its high-strength custom 465 stainless steel material, while BMT Aerospace took care of design, design validation, and post-processing. Both parties showcased the part at their respective Paris Air Show stands last month.
“BMT Aerospace strongly believes in the disruptive potential of additive manufacturing and its possibilities in aerospace,” commented Ewald Goossens, Business Unit Manager of BMT Additive. “As a small player in the market, we strongly believe in the cooperation opportunities like these, where each partner can rely and build a project, starting from its own expertise. Our specific knowledge in design and manufacturing in aerospace, and our abilities in custom design for metal additive manufacturing, are a perfect match with Carpenter Technology’s knowledge of high quality and innovative products.”
“Collaborations like the one with BMT Aerospace demonstrate how partnerships across raw material, production, validation and design can rapidly bring to commercial reality new parts with next step performance potential,” added Marshall Akins, Carpenter’s Vice President for the Aerospace Markets. “Carpenter Additive’s suite of capabilities presents powerful tools to accelerate our customer’s additive aspirations.”
