I probably read about these machines once a year. Simply amazing and continue to fall in price. When I see a decent model drop to $1000 - $2000, I'll be looking more closely.
I wonder what my power bill would look like after a robotic arm moved around for 14 hours... |

I know the price tag on these systems has dropped from 6 figures to 5 recently, but that's still too steep for my pocketbook. There are do-it-yourself versions out there that can be done for around $800. They're nowhere near as sophisticated though. The basic principle is using something similar to a hot glue gun to squirt out plastic as it moved around. The basic machine is similar to a CNC setup except the head on it deposits material rather than removing it.

The RepRap project seems to be getting better, but is still an early, early attempt at something like a rapid proto typer. A far cry from what I need/want in a machine.
I guess, if the rapid prototype machines made parts in a plastic similar to Derlin, or a really hard copolymer, better than urethane resin, I would be more keen on getting one. But has anyone handled a part made from one of the 'glue-n-dust' machines? I have and the part feels really fragile. Like someone used superglue and talcum powder to make the part.
I know that some machine will make parts out of a resin that has properties similar to hard nylon, and that is good.
a CNC mill that can machine a part out of aluminum or steel is what I want! |

I dunno about these smaller ones... but the company my father used to work for had one of the biggest Stereo Lithography machines available.
It made prototype fan blades for Jet Engines to test aerodynamics, and they prototyped patented tools to repair the engines with. I still have a couple small items that were made on the machine out of Corn Starch, I think... can't quite remember.
Oooh for the chance to use that thing... just once. *drool* think of the havoc, errhm, good I could do!
They had all the fun toys... water jet cutters, laser cutters, cnc lathes & routers... come to think of it, they're trying to close one of the plants (not the one my dad worked at) here in CT. I wonder if they have any equipment that they'd like to get rid of... _________________
