Sven Johnson worries about the pitfalls of the shiny new near-future… but not so you don’t have to. In this month’s Future Imperfect, he looks at what might go wrong when prosumer-grade fabrication technology incorporates biotech-powered materials recycling.

While 3D printing may be used predominantly for rapid prototyping of consumer goods (with all the potential risks that entails), it may turn out to have more humanitarian deployments as well. Proving a concept we mentioned a while back, a team of Swiss doctors have used a 3D printer to build replacement bones for a man’s thumb:
Weinand loaded the printer with tricalcium phosphate and a type of polylactic acid – natural structural materials found in the human body. The resulting bone “scaffolds” contained thousands of tiny pores into which bone cells could settle, grow and eventually displace the biodegradable scaffold altogether.
The bones still have to be ‘grown’ around the scaffold (using a surrogate mutant mouse, much like the famous Vacanti ear experiment), so it’s not a completely non-biological process. But it’s a step closer to a world where we can buy spare parts for our meat-machines ‘off the shelf’. [image by ansik]
Following on from yesterday’s post about fabbing your own military hardware, you may be wondering exactly how much of a dent the cutting edge of consumer level 3D-printing technology would put in your pocketbook.
The answer? A personal fabber will cost you just a shade under US$15,000, though the actual printing materials are extra.
Ain’t a lot of money when you think about what it can do, is it? Certainly cheap enough that a reasonably organised criminal syndicate or terror organisation would consider it small change… [via Bruce Sterling; image courtesy Dimension Printing]
Fabrication technology – sometimes known as ‘rapid prototyping’ or 3D printing, among other names – is a real Pandora’s box. The benefits of being able to ‘print’ a solid object are manifold (reduced industrial wastage, low overheads and so on), but the technology doesn’t care what it is that you’re printing out, or who’s doing it… or what they’re doing it for.
This is a topic that Futurismic‘s own Sven Johnson has discussed here and elsewhere, but it’s rapidly moving from the realm of the theoretical into reality. For example, fabrication start-up Shapeways has a video of of a guy who has printed off a miniature remote controlled helicopter:
“So what?”, you might be thinking. But as Bruce Sterling points out:
… all that’s missing from the nightmare scenario is a tiny fabbed bomb and some fabbed GPS. Given those, the Israelis are in for hell on earth.
It’s still a relatively pricey way of doing things, but as the overheads drop the potential of 3d printing to put dangerous tools in the wrong hands rises in parallel with its ability to make our lives better. A rising tide floats all boats, after all.
