Charlie Stross has a post on the new frontier for 3D printing - making clothing - The revolution will not be hand-stitched.
Via MetaFilter, I stumble across the latest development in 3D printing (now that 3D printed handguns have gone mainstream). Mad props go to another printing startup, although that's not what they're marketing themselves as: Fabrican ...
Fabrican is a unlikely-sounding spin-off of the Department of Chemical Engineering, at Imperial College (which in case you're not familiar with it is one of the top engineering/science colleges in the UK; formerly part of the University of London)—at least, it's unlikely until you begin thinking in terms of emulsions, colloids, and the physical chemistry of nanoscale objects. It's basically fabric in a spray can. Tiny fibres suspended in liquid are ejected through a fine nozzle and, as the supernatant evaporates, they adhere to one another. If at this point you're thinking The Jetsons and spray-on clothing, have a cigar: you've fallen for the obvious marketing angle, because if you're trying to market a new product and raise brand awareness among the public, what works better than photographs of serious-faced scientists with paint guns spray-painting hot-looking models with skin-tight instant leotards? (Note: the technical term for this sort of marketing gambit is, or really ought to be, bukake couture.)
The real marketing value pitch is less ambitious, and buried further down the page. Fabrican currently amounts to spray-on felt; a loose mat of unwoven fibres that adhere to one another and naturally entangle. This is brilliant if you're an auto manufacturer, who wants to do away with the laborious hand-fitting of carpets in your cars (just have the paint shop spray the carpet on the floor panels), or a furniture manufacturer who wants to soften the image of those cheap plastic chairs you sell for lecture theatres or buses and commuter rail.
But the implications go much further, because this is just step one. What we're looking at is the first sign of the shift to 3D printing of clothing.
