Metal 3D Printing

Proprietary

• Desktop metal - [1]
• Robots + Mig Welders - [2]. Cost of MIG wire is $2/lb, so overall cost is reasonable. Imagine 3D metal printing for rebar forms combined with Clay Extrusion to make rebar reinforced Earthen Construction all with industrial robots.

Open Source

• MTU early MIG-welder based printer - [3]

• Part release mechanisms - [4]

Print and Sinter Filaments

• You can print with regular plastic filament. [5]
• You can print in clay and then bake.
