I lead the design team responsible for the first object to even be printed from a Meteroite.
Planetary Resources, in collaboration with partner 3D Systems, have developed the first ever direct metal print from asteroid metals.
This spacecraft prototype was 3D printed from an actual asteroid that was pulverized, powdered, processed then printed on 3D Systems ProX DMP 320 metals 3D printer. The asteroid was melted under vacuum then gas atomized into powder by Allegheny Technologies, Inc. at their ATI Powder Metals research facility in Pittsburgh, PA.
Egg Shell Casting is a casting technique used in complex silicon molding applications. Leveraging various 3D Printing technologies, we create ultra thin molds that silicon can be injected into. The molds then are broken apart much like an egg shell revealing the finished silicon part. This technique can create complex shapes not previously achievable in many materials.
