The most Affordable Desktop metal 3D printing
The most affordable desktop metal 3d printing based on aluminum extrusion method to produce a metallic parts. This method use special designed extruder to melt the aluminum and push it under pressurized argon gas through 0.3mm nuzzle. Theoretically the wall thickness of printed parts can be almost the same as the nuzzle size.
Also, there is short YouTube video.
The main focus is Extruder. Extruder drawings under development. Waiting for few testing procedures and finalizing drawings.
3D printer mechanics design
The printer itself should be constructed with metallic parts, should be shielded gas proof (argon/nitrogen) and the table of printer should not be movable to hold massive substrate.
The extruder under development and hopefully will be available in few months. The page will be updated accordingly.
