Friction Welding & Cold Spray Additive Techniques

January 20, 2015

Testing friction welding some 3D prints with a Dremel today! Great method for quickly assembling parts without glue.

 


A more advanced technology called Cold Spray has incredible value in space construction.
Essentially similar to Friction Welding, micro particles are accelerated to supersonic speeds where they collide with objects to be joined. On Earth we need Helium or energy expensive vacuums and particle accelerators to accomplish this. In space it should be much simpler. All we'll need is materials mined from lunar soil, asteroids, comets or transported from Earth and a light gas expansion system to weld with. Note to astronauts... hold on tight!. 

Here's the original post from the guys at Scorch Works.
