- The proposed 3D printer uses fusion welds in a vacuum to create metallic objects. The range of metals and alloys is not restricted to low melting points (e.g. 450 C).
- Other viable materials could include molten, electrically conductive materials like borosilicate glass. If a sputtering system were included, viable materials for deposition greatly increase.
- The idea is this: apply a controlled amount of molted metal onto a surface (which could be previous layers), allowing the new and old metal to fuse through high heat. Oxidization is prevented by welding in a vacuum. Proper preparation of the surface could include a) melting and pouring the metal, b) mechanically cleaning the surface, or c) melting the leading edge of the metal at or close to the site of welding.
- Expect pictures, numbers, and costs of equipment sometime soon.
