Desktop fabricator may start home revolution

A cheap self-assembly device capable of fabricating 3D objects has been developed by US researchers. They hope the machine could kick start a revolution in home fabrication - or "rapid prototyping" - just as early computer kits sparked an explosion in home computing.

The standard version of their Freeform fabricator – or "fabber" – is about the size of a microwave oven and can be assembled for around $2400 (£1200). It can generate 3D objects from plastic and various other materials. Full documentation on how to build and operate the machine, along with all the software required, are available on the Fab@Home website, and all designs, documents and software have been released for free.

The machine connects to a desktop computer running software that controls its operation. It then creates objects layer-by-layer by squeezing material from a mechanically-controlled syringe. A video shows a completed machine constructing a silicone bulb.

Malone and Lipson hope Fab@Home will grow into a community of enthusiasts who share designs for 3D objects and even modify the machines for themselves. This will prompt the emergence of widespread personal fabrication, Lipson hopes.

Want. If the quality is good enough, that is. Simple objects, like bulbs, may be easy; but it gets interesting with complex stuff, like human/animal figures. It would be fun to position a modelkit in eg Poser and then print it out.
