Additive mfg (3D Printing) technologies are evolving so rapidly that one needs to stay on its toes to follow all new leads. Many researchers are focused on developing new technologies while others working tirelessly to improvise the existing ones. Follow my blog if you want to witness the unfolding of next industrial revolution.
Another variant of Metal Jetting combined with Polyjet in the works by Desktop-Metal. This is ultimate solution for high volume metal parts production as per DM. The method claimed to be 100 times faster and 20 times cheaper than current laser based systems in the market.
HP's Metal Jet Printing method is very similar to Single-pass jetting announced by Desktop Metal (DM) few months ago. Most of the new methods are targeting to address the printing speed as this is one big hurdle in progressing additive manufacturing to next level. Few variants of metal jetting methods have been announced during the span of last couple years, HP's Metal-Jet being the latest.
Focus is to offer more affordable solutions. These methods may not be able to print highly detailed parts but certainly offer more affordable solution for industry at large. Metal-jet methods have been serving tooling and fixturing needs in the industry very successfully.
