Metal 3D Printing

Introduction
Metal powders laser sintered are a way to achieve high quality prints. This technology is near open source. By combining an open source laser such as Lasersaur with Open Source Selective Laser Sintering - high performance 3D printed metal parts are around the corner. This would be an advanced version of the existing rought 3D metal printing with robotic welders - see Open Source 3D Metal Printing.
The missing link for open source metal 3D printing is powdered metals. They appear to be accessible, though - such as iron - at only $1/kg. See Metal Powders.
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.

Print and Sinter Filaments
- You can print with regular plastic filament. [5]
- You can print in clay and then bake. See Metal Clay Printer.
