This is a bit too good to believe, but at $100 i'll bite. I've been into 3d printing for years now, and my main concern is material. If this resin is durable, and doesn't get soft in the car on a warm day, this design could be really groundbreaking. If not, it'll be a waste of everyone's time. The quality looks pretty decent given how awful low end 3d printers can be without a ton of tinkering. My current printer cost me about 2K and ABS/PLA at $40ish/kg actually adds up when prototyping. I'd love to have something really cheap like this to test out prints before finalizing them in ABS.
Eh, only if you make the large-ish thing solid - this can easily make hollow / drain-able structures. And since it's partially supported by the liquid as it's built, you don't need as much temporary supporting structure as an extruded plastic version.
