Something I'd like to see from the hobbyist community: DIY injection molding.
Injection molding is a process where the first one is a huge amount of work, and then you just bang them out for a few cents each. Which is why most of the world's cheap stuff is injection molded.
TechShop used to have the machine for it, but it was very rarely used. The injection molding machine was about the size of a benchtop drill press. It had fixtures to hold two dies, a pressure pump, and a guard around the molding area in case something went wrong.
There's an automated one coming out as a kickstarter. Pre-order for $6500.[1]
Now you need to make injection molding dies. This requires a milling machine, and is much easier with software support. The commercial software for planning injection molding is Autodesk Moldflow, but that's overkill for simpler projects. TechShop had that on their computers, but nobody ever used it. There's something called OpenFOAM, but it's not a nice GUI program.
