Okay, this one's actually useful outside of niches.
Next-level 3D printing: Terminator Style
So using UV light, oxygen, and a pool of liquid resin, it's possible to shape much more complex shapes in an order of magnitude less time.
W-wait, isn't this how 3D printers work already‽
Conventional 3d printers deposit layers of material onto the object. This draws them out in a continuous stream by curing the resin.
3D resin based approaches using UV laser predate binder+powder, and extrusion tech by at least a decade. Binder + cut paper is older still.
Each tech has downsides and upsides. Powder+binder is cheap, and the powder provides support during the build process, (something that UV cured additive resin cant do. scaffolds have to be printed at the same time as the prototype in order to support the prototype as it is built.) but the resulting prototypes are very fragile. Paper+binder is cheap, but slow, and not all that accurate. (combination of 2D cnc vinyl cutter tech, with a table with Z axis drop, a glue spreader, and a big roll of paper that provides the layer. It is prone to warping and getting bubbles between layers.)
This tech sounds like an incremental upgrade to cured resin 3D printing. Not much more.
The "Molecular assembler" 3D printer that hit the news recently, which is able to assemble objects using chemical processes, and can produce complex chemical compounds, is far more novel and would have far more interesting applications.
