Goal : make a die for sheet metal forming that bears 400 bar pressure
Helicopter factory needs a mold for sheet metal forming. The die must bear 400 bar pressure.
Plywood’s — traditional material — lifespan is too short. The metal die would work longer but costs significantly more.
The best option to extend a lifespan and reduce costs is to print a die with continuous composite fiber on Anisoprint Composer 3D printer.
Anisoprinting technology reduces costs 2-4 times while raising durability.
Anisoprinting is the technology for design and production of optimal composite structures through composite fiber co-extrusion. Thermoplastic polymers are reinforced with continuous fibers, consolidated and cured within a single-stage fully automated process, with no post-processing required. The inner part of the fixture has lattice (isogrid) structure: during printing, fibers are layed up along the loading direction to achieve the best combination of strength and weight.
