This is so cool! And it's from 2013, thats amazing. A very similar printing method is being explored by MIT's Self Assembly lab, I think they first published in 2017 - https://selfassemblylab.mit.edu/rapid-liquid-printing https://www.liebertpub.com/doi/full/10.1089/3dp.2017.0037

His whole website is an absolute goldmine of awesome projects and hacks. I thought this was really cool: Optical Mouse Cam: https://spritesmods.com/?art=mouseeye

The non-obvious way to greatly speed this method up is to use an array of nozzles and dip them all at the same time. Draw them upward while squirting your resin at the appropriate times and you have a 3D printer that prints as fast as you can move something up and down...

Imagine a sewing machine, but every time it moves up a 3D part is left behind in a binder. A new container is whisked in to replace it and the process repeats. Patent #10,870,239 issued, and more are pending :)
