In 2013, the lab of Prof. Joshua Pearce at Michigan Tech had designed an open source metal 3D printer that could be assembled for less than $2,000. The lab is still working hard on their technology and, today, published a breakthrough that could be applicable to metal 3D printing as a whole and, more importantly, reduces the cost of metal 3D printing with their system even further.
Typically, metal 3D printing requires the use of a metal substrate, onto which the part is fabricated. …
