They now offer a bare bones option.

This is legit. I’ve been following Kobus’s work on this for the last year or two. There are working review units in the wild and the tech looks really good. It’s a top-down DLP printer with some really clever features. The super-speed version has print speed rivaling Carbon3D’s CLIP… except you can actually buy this Gizmo 3D printer now for a pretty reasonable price.
As of today (22nd) only one more backer is needed to hit the funding target and get this production run going.
@Ryan_Carlyle been following them for a while to. help spread the word so they can now meet there stretched goals.
No external galvo mirrors to keep clean since it’s a DLP printer, but I’m pretty sure it has a cover to keep dust and light out. Resin flow is the main speed limit at the high end of light intensity (i.e. with close projector focus and dual projectors) to my understanding, and there’s some resolution/quality degradation at top speeds. “You can make it print so fast the quality declines a bit” is a really good problem to have, in my opinion. Lets you pick where on the speed/quality spectrum you want to be.
There is no flow to the resin. The build plate lowers into the tank from the top to the bottom.
The resin has to flow over the print otherwise you get defects.
Bottom-up printers also have resin flow issues… Can’t peel large objects very fast or they detach from the bed due to suction.
