BAE systems (Farnborough, UK) reported on May 20 that he was using large-scale 3D printing to produce high temperature mold tooling using Dahltram I-350CF resin from Airtech (Huntington Beach, CA, States United) for the production of a future combat air demonstrator.
Dahltram I-350CF System is a PEI-based, carbon fiber reinforced, high temperature capable 3D printing resin which has been adopted by the aerospace industry. BAE Systems claims to have worked on the development of the manufacturing process with Airtech Advanced Materials Group and Ingersoll Machine Tools, Inc. (Rockford, Ill., USA) who printed the mold tool on its printing platform Large format 3D MasterPrint.
The Dahltram range of resins are suitable for multiple printing platforms, providing production flexibility with end-use material approvals. Airtech was able to demonstrate its technological availability and its manufacturing capacity with its range of Dahltram resins and its own in-house 3D tooling printing service. Continuous thermal cycling testing, pressure leak testing, laser surface scanning and contact material testing would have generated data supporting over 250 autoclave cycles, without degradation of tooling manufactured by Dahltram . Airtech Advanced Materials Group also has Dahltram additive manufacturing resins and large-scale Print-Tech 3D printed tool manufacturing capability in the United States and Europe.
