A 3D Printer On Every Desktop? 426

Posted by kdawson from the abs-fab dept.
holy_calamity writes "Two Cornell researchers have designed an open source 3D printer that costs just $2,400. The self-assembly kit is part of what they call the Fab@Home project — they hope it will spark development of rapid prototyping for the consumer market in the same way the Altair 8800 did for personal computing in seventies." Here is a video showing a completed machine constructing a silicone bulb (16-MB WMV).
Update: 01/10 04:02 GMT by KD : The developers of this kit are at Cornell, not Carnegie Mellon University as the original post erroneously stated.

        Nah, that will never happen.

        Surgeons buy pieces from Dow because Dow has spent a lot of time and money certifying the safety of their process and parts with (among others) the FDA. Surgeons buy the parts, and don't have to be too concerned that a manufacturing defect or bad batch of materials slipped past QA. If (God forbid) QA flubs one, the surgeon can (legitimately) blame Dow. If you're doing the QA in your office, however...

        While part of the (exorbitant amounts of) money spent on any sort of health care ensures that everyone involved makes a tidy profit, you are paying much more for the guarantee of safety than anything else.

        In essence, silicone is cheap; the insurance and hassle involved with making a safe part is very much the antithesis of cheap.

Computing has already accepted open source for software, there's some effort of open source hardware designs going on.

There is no time mark on the video so there is no indication of how long this thing took to build. The shape is brain-dead simple. Can it spin anything more complex than a circle as it builds? What good is a printer that can only make balls, cylinders, and bulbs? Presumably this item is flexible being made of silicone rubber, but that seems to be more a side effect of it being built on the cheap with off the shelf materials. It even had to be "refilled" half way through building this rather small bulb, which is mostly air to start with!

    For all the people than mentioned using this device to repair things around the house, I hope the only thing that ever breaks around your house is your turkey baster (assuming this thing can print a bulb that large).

    As has been mentioned by other posters, these machines will only become truly useful when they can extrude a variety of materials with a variety of material properties. I would imagine you could get a range of properties in stiffness and heat resistance by varying proportions of two or three basic plastic polymers with perhaps a few additional curing additives. Rather than demand a 100% build from scratch perhaps a few standard sized metal reinforcement parts could be thrown into the mix, though this would require a pause while the machine requested user assistance to add screws, rings, dowels, or thread a wire or two.

    Really useful auto manufacturing will require serious breakthroughs in AI and robotics to assembling a variety of fabricated parts into something useful, only then will manufacturing prices plummet.
