He once 3D printed a 3D printer

Yes, we stole that from The Most Interesting Man in the World. This, however, pales in comparison to what researchers at Brown University developed. And in case you’re feeling smart today, the title of their article in the Lab on a Chip journal is “Stereolithographic printing of ionically-crosslinked alginate hydrogels for degradable biomaterials and microfluidics.” There are more words we don’t understand in the abstract, but to cut to the chase, this method of printing “may enable adaptive and stimuli-responsive biomaterials, which could be utilized for bio-inspired sensing, actuation, drug delivery, and tissue engineering.” Essentially, biomaterial can now be removed or reversed (degradable) layer-by-layer in a controlled manner, opening possibilities for biopharmaceutical production and/or the controlled release of living cells or drugs and/or for use in artificial tissues. Isn’t science weird?
