I am in the planning stages of a 3D Printer. I want to make a beefy one. I am thinking of going the sintered Metal dust route with a beefy ass laser, then stick it in a kiln to make it solid. I could make gears that way., just about anything, really. The video below demonstrates what I'd like, but not the machine I want, this one is big bucks!! The second video is what dreams are made of!
