Carbon3D – 3D Printing via Continuous Liquid Interface Production

The site is so cool that it just screams "fake". Cool pictures, not much copy, no details.

The big difference here is that they're doing photopolymerization at the bottom of the tank, rather than at the top like everybody else. This requires a transparent material that passes oxygen on the bottom of the tank, so the action takes place on the surface of that membrane.

They're vague about the details. How long does the membrane last? Is it an expensive consumable? Is the process gas air, or pure oxygen? Why do all the videos show the object being built slightly out of focus?

It seems to generate smooth surfaces nicely, but none of the examples have fine detail or sharp corners.

They've raised 40m from Sequoia, so it's reasonable to conclude there's been some degree of vetting. Given that they show video of a working prototype it's very likely this vetting included independent observation of their printer in action. Their product might be useless for some other reason, but if so it's non-obvious enough for them to have raised a non-trivial amount of money.

Clinkle did raise 25 million as well, nevertheless this looks cool and hope it is affordable.

They do have a video of the actual product at the bottom, which is just plain cool.

I don't know much about 3D printing, but that's the most futuristic video I've seen this decade. It looks like it could just pull a coffee mug or whatever out of nothing and serve it.

If you like this search for "stereolithography" on YouTube ;)

Coffee mug :) I was thinking X-Files alien fetus.

I'm glad you pointed that out, because I completely missed it.

Ya, they really ought to move that to the top. It's amazing.

There is an address and real people on the site. I wouldn't call fake.
