It is indeed an additive process. The process is called sheet lamination and this application seems to be combined with material jetting process. In SLM, DED, etc, nearly every single part needs post processing. If we dont consider it additive because of the post processing, nearly every additive application would be considered hybrid. There are a number of different additive methods and they all have their applications. SLM/SLS is extremely expensive. Not sure how much this system costs, but I would venture to guess that SLM is not cheaper. A DED additive system such as Meltio is 250k USD plus more for options. And that is a relatively low priced DED system. A Matsuura Lumex is over $1m as of a few years ago (powder bed fusion machine). Then the costs of the powders ($$) and the safety equipment and handling processes, etc. Then the NDT processes and equipment, etc. The wire EDM to separate the part from the build plate, the milling machine to resurface the build plates. Its no small feat to implement SLM/SLS. So I would say that it is definitely not cheaper than this process. This process however, looks to be SIGNIFICANTLY faster than SLM as well.

what do you do with the used sheets? since you are jetting away the material off the sheet it seems like its still subtractive manufacturing with extra steps?

Would this work making molds, or are their better methods? Or are molds obsolete? I'm not up on the current manufacturing tech.
