A 3D Printer On Every Desktop?

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.

  1. The uses are endless by traindirector · · Score: 5, Insightful

    Building and using one of these seems like a fun and even practical hobby. Ever get frustrated at the plastic parts that break and render something useless? Now you can make replacements. Ever wonder what to get for the person who has everything? Well, I'm pretty sure you could make them a lot of neat personalized things with one of these that they'll be stumped as to where you could have found them.

    This project obviously has a long way to go, but I think the comparison to early personal computers could be fair, given the huge realm of possibilities creating objects in 3D space opens.

  3. We need something like this for transistors by AuMatar · · Score: 5, Interesting

    When I read fab I was so hoping it could print out a working circuitboard from a custom design. Don't get me wrong, this is cool too. But imagine if we could get a circuit one. Computing has already accepted open source for software, there's some effort of open source hardware designs going on. With the equivalent of this for circuits, we'd put the ability to make new electronics designs in the hands of thousands of hobbyists. Just look at all the cool stuff that hobbyists have made with software, imagine what we be invented if they had hardware as well!

    Now that I think of it- the combination of that and this would be truely awesome. A talented hacker, or a small team, could design software, hardware, and test out of their own homes without expensive produciton costs. It'd be a huge breakthrough.

  4. Amazing by saladpuncher · · Score: 5, Insightful

    Seems a little expensive. Could someone build one of these printers and then print the printer itself and mail it to me? I promise to duplicate it as well and give some to my friends. Seriously though, if I owned a manufacturing company of any any kind I would be scared of this thing. In 30 years you might witness the end of large scale production of small consumer goods. Throwing a party? Print up the plates and forks and chairs and tables you need. Need a gift? Print up some Barbie dolls. In 50 years the only thing that might actually be sold are the plans needed to fabricate something and the "ink" for this thing. If I was very cynical I would say this could end capitalism itself :)

  9. Looks more like science fair project by DumbSwede · · Score: 5, Interesting

    Call me a cynic, but this thing hardly looks ready for primetime. In fact it looks to work far worse than 3D prototype printers I saw demonstrated 5-7 years ago did.

    "Two Carnegie Mellon researchers..." translation: "Two graduate students' thesis project"

    For those that didn't watch the video, it looks like a time-lapse speed up of a caterpillar building a cocoon. Seriously it has an almost creepy organic look. 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. Keep in mind we have had auto-milling machines for decades and they haven't obsoleted most manufacturing processes. They can also mill into custom shapes a much wider range of materials.
