Metal injection molded components are used in the Eurofighter Typhoon as part of a strategy to reduce costs without compromising performance. A validation study on MIM was conducted by Pratt & Whiney and MTU Aero Engines of Germany with promising results. MIM components will be used in the EJ200 engine in the Eurofighter.. Blades and vanes in the turbine have usually been cast but MTU says the new MIM vanes combine the cost advantage of cast metal with the strength of forged metal. The MIM parts achieve 95% of the strength of forged parts. The power of the engine makes it a key combat aircraft for NATO forces,
An MIT research team has invented what they see as a solution to the need for biodegradable 3D-printable materials made from something besides petroleum-based sources: a water-based robotic additive extrusion method that makes objects from biodegradable hydrogel composites.
Alcoa has unveiled a new manufacturing and materials technology for making aluminum sheet, aimed especially at automotive, industrial, and packaging applications. If all its claims are true, this is a major breakthrough, and may convince more automotive engineers to use aluminum.
NASA has just installed a giant robot to help in its research on composite aerospace materials, like those used for the Orion spacecraft. The agency wants to shave the time it takes to get composites through design, test, and manufacturing stages.
The European Space Agency (ESA) is working with architects Foster + Partners to test the possibility of using lunar regolith, or moon rocks, and 3D printing to make structures for use on the moon. A new video shows some cool animations of a hypothetical lunar mission that carries out this vision.
