Design freedom due to additive manufacturing

technology report online, November 2016

Amorphous Metals are a highly sought-after group of materials for 3D printing and make a near net shape manufacturing of high-strength components with complex geometries and sophisticated designs possible.

3D printing is everywhere. The medical, automotive, and aerospace industries need new metal materials for making structural and functional components that are resistant to high temperatures. The challenges of 3D printing begin with manufacturing the powder. Expertise in materials and processes is crucial, because the metal powder and the printing process must be individually matched with the desired component. Heraeus has been developing sophisticated metal powders and the related processes for 3D printing since 2015.

Heraeus now demonstrates additive manufacturing with amorphous metals for the first time and has expanded its portfolio of 3D printed metals with this highly sought-after group of materials through a technology partnership. Amorphous metals are suitable for an exceptional number of high-tech applications. They are shock-absorbing and scratch-proof, while still having very good elastic properties – making them an attractive option for injectiors, casings for consumer electronics, and dome tweeters for speakers.

Thanks to additive manufacturing, bulk amorphous metals with new design possibilities will for the first time be broadly accessible to a mass market – not only in their long-awaited use as a structural material, but also in the near net shape manufacturing of high-strength components with complex geometries and sophisticated designs.
