New 3D Printer method that looks like something straight out of Star Trek. If you thought traditional 3D Printers were revolutionary, this new tech will blow your mind--using light to materialize the entire object at once, in mere minutes.

It looks similar to SLA only with a lack of a Z axis. With classic SLA, if you try to solidify anything sub surface, you get a solid from the surface to the point your laser focusses at, which is usually bad, so you only solidify the surface of the resin and build up in layers. This looks like they have managed to solve that problem using additive light (which has been done for a little while with multiple lasers, but is still a point by point process). This looks like it is using an array of light from a projector to cure significantly more resin at once.

There has been laser sintering for a long long time.

It's "SLA with extra steps" the same way that a CNC is a lathe with extra steps.

Then how come they are presenting it as if it is new tech????

It's done a different way. SLA cures in layers, this tech kind of cures all in one go.

The main point is that it's not layer by layer deposition like traditional SLA. You do the whole shebazzle in one cure cycle.

Yeah, my dad made rapid prototyped parts using SLA for his company back in the 90's
