We could probably start a dedicated 3D printing thread and have new material every month.
Here's a new technique by Carbon 3D called continuous liquid interface production that claims to be 25-100 times faster than any other method.

Quote:To accomplish this, these scientists took advantage of a problem typically associated with 3D printing methods that relies on light to initiate polymerization (photo-polymerization): the ability to control oxygen levels. When present, oxygen reacts with the polymerizing chains, which significantly slows down the reaction. Oxygen must therefore be limited for the curing process, which hardens the product. In 3D printing, the material is typically printed in air and cured under a UV light; since oxygen is likely present, this process is slower than it could be.
The new technique proceeds by projecting a continuous sequence of UV images through the bottom of an oxygen-permeable, UV-transparent window. The window is below a liquid resin bath that is essentially a solution of chemical reactants. This window allows a small amount of oxygen to enter, creating a “dead zone” where the curing process cannot proceed. As a result, the dead zone maintains a liquid interface directly above it. The UV images then pattern the structure as it emerges from the dead zone.
I can't remember where this verse is from, I think it got removed from canon:
"I don't hang around with mostly men because I'm gay. It's because men are better than women. Better trained, better equipped...better. Just better! I'm not gay."
For context, this is the previous verse:
"Hi Jesus" -robvalue
