I've read a few posts on the intarwebs on this printer but I still don't get the oxygen part and how that would somehow eliminate layer lines?

    "The oxygen thus acts to inhibit the resin from curing in certain areas as the light cures those areas not exposed to the oxygen. Thus the oxygen is able to create a ‘dead zone’

    within the resin which is as small as tens of microns thick (about the diameter of 2-3 red blood cells). In this subsection of the resin, it is literally impossible for photopolymerization to take place."

    To my understanding, this means that the resin is pushed away, by the oxygen, from the areas that's being printed, so that the UV light only hits that part.

    Unlike SLA, where beams of UV light is projected to different areas to cure the resin, this CLIP does it so that the UV light is continuously projected on the whole area, and the oxygen determines where the resin is cured.

    When this is done in a continuous motion there won't be any layers although, in a way, the parts are still being built layer per layer.

    I think its the most interesting development in 3D printing I have ever seen... but I bet those gadgets are gonna be $£$£$£$£$

    Here's a TED talk about this:

    You mean SLA right? This is still SLA by the looks of it. They fine-tuned and developed it, but it is still the photo curing of resin. I do not see a fundamental difference to call it a truly different technology. If this all pans out they certainly added to it, but the basis it still the same.

    I sure did. edited. Yeah, i guess calling it a new technology is a bit wrong.

    That is awesome! I can imagine extremely pricey though
