Transcript

My friend Eric invented a new type of three d printer that can make human teeth and a whole lot of other things. One year ago, Eric was working for an industrial resin printer. But he decided to quit his job three weeks ago because he's an idiot who hates money, but also because he's a genius. You see, resin printers can print at a way higher resolution than normal three d printers. But since it uses light to solidify plastic in a single pool of resin, it can only make objects in one color or material. But Eric has a new Patent took. Technology. The printer will switch between any material you want rank clean off the residue by spinning at a million RPM, which lets you have hyper detailed colors, dissolvable supports, and even conductive materials all in the same print. So one day, you'll be able to make a phone from your home. He's gonna demo his invention and possibly start preorders at the Blueprint Best, where 100 founders will show off their inventions from the last month of working in our hardware lab.
