Japanese company, Mutoh has just unveiled a new 3D metal printer called the Value Arc MA5000-S1, and like its name suggests, it prints using arc welding technology. Not the first arc welding machine we have seen that has been used for 3D printing, but it is the first by a large company. It can not print in the same detail as more conventional DMLS/SLS or EBM machines are capable of, but it can print a lot faster with much more affordability.
