MakerBot's composite materials will create things you'll want to keep
Enough with the primary-colored plastic trinkets. When can we start printing things we want? Things we'll use? While we're still not quite there, MakerBot's recently announced composite materials might get us closer. We talked to MakerBot's Director of Product Anthony Moschella about a year in 3D printing. He told us about the "chain of pain" that once was getting an idea or a design from brain to reality, how MakerBot's trying to smooth that process, and we sniffed a pseudo-maplewood hammer. For a reason. Watch it unfold below.
MakerBot wants you to start 3D-printing in metal and wood (sort of)
The future of 3D printing may depend on the ability print things with properties beyond cheap plastic. We've seen composite materials appear for 3D printers before, but the arrival of MakerBot to the scene should make progress a bit quicker. Announced at this week's CES, MakerBot will be rolling out new composite filaments that have been chemically bonded with new materials. You'll have to wait until late 2015, but it's probably going to be worth it: Maplewood, limestone, iron and bronze PLA composites are coming. And in real life, they look and feel far more impressive than you might think.
Paper alloy takes shape for biodegradable consumer electronics (write your own origami joke)
So you're anxiously awaiting your biodegradable car and your biodegradable 3D glasses, waiting for the day when everything you own can return to the loam from which it sprang. But, what about the computer you're using this very moment? It's probably made of non-green materials like injection-molded plastic, and slapping some bamboo on it isn't fooling anyone. Design and engineering firm PEGA comes to your rescue with a new composite material made of recycled paper and polypropylene alloy. Lightweight, durable, and inexpensive to produce, it acts just like typical ABS plastic -- and it even comes in the classic soul-killing beige. Maybe this is what Apple's been waiting for.
Kenneth Cobonpue's biodegradable car: time to ditch the Gremlin rusting in your yard
Is there any sadder sight than a 1958 Plymouth Fury rotting in the woods, Christine-style, its dead headlights staring into the gloaming? We don't think so. That's why we're downright giddy over Kenneth Cobonpue's Phoenix roadster, a biodegradable concept car made from bamboo, rattan, steel and nylon. Style wise, it's propped somewhere between Tata's Nano and Tesla's Roadster, and there's no word yet on what might go under the hood -- presumably a smallish electric engine... or a stardust-powered unicorn, perhaps. That funky-looking body should last the average length of ownership; after five years (or even longer, depending on the composition), it can be replaced or naturally returned to the Ma Earth. One potential downside of biodegradable vehicles? No more "dead car" Flickr albums. Also, no warranties.
Graphene-polymer hybrid composites look to oust carbon nanotubes
We're pretty certain the world's big enough for the both of 'em, but a graphene-polymer hybrid developed by a brilliant team from Northwestern University could prove to be a suitable -- and much cheaper -- alternative to polymer-infused carbon nanotubes. Put simply, graphite can be purchased for dollars per pound, while single-walled nanotubes are hundreds of dollars per gram. A breakthrough has found that tough, lightweight materials can be created by "spreading a small amount of graphene, a single-layer flat sheet of carbon atoms, throughout polymers," and these composites could eventually be used to make lighter car and airplane parts (among other things). We won't kid you, there's a lot of technobabble in the read link below, but it's well worth the read if your inner nerd is up for it.
