MIT Researcher Demos Self-Assembling Objects

Posted by Unknown on from the grey-goo-scenario dept.

iONiUM writes "From the article: 'Many are only just getting their heads around the idea of 3D printing but scientists at MIT are already working on an upgrade: 4D printing. At the TED conference in Los Angeles, architect and computer scientist Skylar Tibbits showed how the process allows objects to self-assemble.' There could be many applications for this. Definitely a cool step forward." Pictures and video of the process.

      I fully support the construction of replicators and all of the cool things that can be done with that. It would be pretty sweet if we could make self assembling cities. We could build entirely new cities that are VASTLY more efficient than the kinds of cities we use now. I would love to see the human race move to using arcologies.

      Uh, dude, human beings are already uncontrolled replicators. Green Goo flooded the planet a few billion years ago, followed not long after by Pink Goo. If we ever manage to (or even bother too, it's not a particularly efficient manufacturing method) create Grey Goo, it would have to beat off a lot of competition from existing replicators before it could start spreading.

    Industrial Origami, Inc. is way ahead here. They have a set of techniques for designing punched sheet metal parts which then bend to fold up neatly into boxes or other desired forms. The folded surfaces bend precisely, even when bent by hand. The edges meet and lock together. I've folded up one of their electrical boxes, which comes as a flat sheet ready for hand folding.

    It's all done with clever design and finite element analysis to get the bend points to behave in a repeatable way. What they sell is design software for doing this.

      Computer controlled metal bending has been around for decades. Over 20 years ago when I was at Disney the contractors were using a computer bender for rebar. The auto industry was the first to use computer bending on a large scale. What's new is using heat from lasers to bend the parts. Yeah the videos have been sped up 3X or 4X but it seemed to work quite well. Heat bending plastic can be a bit of an art form so I would question what the reject rate is like? The biggest downside a lot of these processes have is speed. It's like printing a car body. If you've got to tie up a multi million dollar machine for weeks to print a car it's just a toy and has no commercial value. Until the can produce one in a similar time frame to current production lines it's pointless. The technology won't get a lot faster due to the physics of heating and depositing plastics so going to expensive multihead machines is the only option. Laser cutters and benders have similar issues since above a certain temperature the plastics and metals will distort and burn.

      I handled and hand-folded some of their flattened-out parts when they were making a pitch for VC funding at a conference. It's quite striking. Things fold easily where they're supposed to, and click together neatly. It's easier than assembling cardboard boxes that come as flats.

      If you wanted self-assembly, you could add sections of nitinol (the shape-memory metal) and use them to power the assembly.
