This looks an awfull lot like 3d printing to me

#12This is very similar to a patent I have filed on extremely fast 3D printing.
I have mentioned this method of 3D printing here previously. Transmitting data to a volume at high speed can be done in many different ways, at any scale, and with a variety of materials.
I hope to someday demonstrate the printing of a 2 story concrete house in an hour using my technique.

#13Uh, that's a standard resin printer. Except horizontal plus rotation instead of vertical. Trades angular resolution for vertical. Yes, they can be fast. They should fix their headlines.
Could multiple projectors (at e.g., 120 or 90 degree angles) be used to speed the process further?

#14This is new to me and looks really cool despite the sensational style of journalism. I imagine in the near future we will have a variety of widely available methods for making physical objects from digital models, each with advantages and disadvantages for different usecases.

In the sense that from a 2D representation a 3D object is created, yes, but that's it.

#16I don't fully understand the process of creating 3D video from 2D slices. Is that some sort of holographic procedure?
Presumably such a video could also easily be computed from CAD models, right?

#17So it can make you "tea, earl grey, hot" or anything else ... but made only out of unbcoloured acrylic resin.
I thought the same when I clicked on the link with hopes high...

Has the application published? Would you mind putting the link here? I'd like to read it.

#19This looks like it's wasting a lot of material comparing to DLP printers.
They could probably 3d print multiple parts inside the liquid simultaneously.
Then it becomes a "fill the cylinder" optimization problem.

#20The speed is amazing but the amount of waste seems rather large as they most likely can't (re)use resin that has already absorbed (an unknown amount of) light before.
It doesn't work like that. It's like a match: put enough energy in, and it transitions to a new state. Put less than the activation energy in, and it doesn't. The energy you've put in will be lost as heat, but the resin is unchanged until it changes completely.
