Open Sourcing 3D Printer Materials

I've written a fair amount about open source fabbers, but here's someone addressing another important aspect: open sourcing how to make the basic material used by 3D printers:

About five years ago, Mark Ganter, a UW mechanical engineering professor and longtime practitioner of 3-D printing, became frustrated with the high cost of commercial materials and began experimenting with his own formulas. He and his students gradually developed a home-brew approach, replacing a proprietary mix with artists' ceramic powder blended with sugar and maltodextrin, a nutritional supplement. The results are printed in a recent issue of Ceramics Monthly. Co-authors are Duane Storti, UW associate professor of mechanical engineering, and Ben Utela, a former UW doctoral student.

"Normally these supplies cost $30 to $50 a pound. Our materials cost less than a dollar a pound," said Ganter. He said he wants to distribute the free recipes in order to democratize 3-D printing and expand the range of printable objects.

Fab(bers)

And talking of fabbers, this is cool (and open source):

Adrian (left) and Vik (right) with a parent RepRap machine, made on a conventional rapid prototyper, and the first complete working child RepRap machine, made by the RepRap on the left. The child machine made its first successful grandchild part at 14:00 hours UTC on 29 May 2008 at Bath University in the UK, a few minutes after it was assembled.

That is, a fabber that can replicate itself....

Can the singularity be far behind?
