Cabe, Thats really an interesting article and i am too much surprised and excited to hear that 3D printing can be done with sugar .This is indeed a very sweet concept .But is 3D printing with sugar safe ?what i beleive is that sugar melts at particular temperature doesnt that object also gets melted . Secondly do we have to protect the sugar 3D printed object with insects . Is this printing long lasting ?
Prining with sugar would also be a good way to make positives for casting many materials. The finished sugar object could simply be disolved from inside the coating, not quite like the lost wax or styrofoam processes, but using water instead of heat. Much less enviromental impact, I think, and all done at low temperature. And the material is cheaper.
Of course, making edible decorations is a nice niche to be in because hereis not much competition, at least not yet.And for those who complain about the sugar being unhealthy, this is probably expensive enough to prevent a whole lot of consumption.
And about the melting temperature; softening and reduction of bond strength happen at much lower temperatures than the melting point, as with many other materials.
Charles, The vans that I've referred to showcase edible fruit, vegetables which have been artistically decorated into an arrangement, and are then consumed at various galas, functions, meetings, receptions, etc. These are for EATING, not for decoration, but they've been "stylized" to add to the decorum of the events.
Another blogger commented about "IMHO" (whatever that means???) ,and called it wasteful...... IF people consume the end product, then WHY is it wasteful????
You can read the Penn press release about this awesome science, an overview from Science News, or the full paper. A more detailed post about the hardware used in this project will follow and soon you'll be able to make your own sugar extruder. (It prints chocolate too!)
A biochemist was looking for a way to print blood vessels to make kidneys. He went to hive76 to see if they can print in sugar - they figured it out.
So - old news - a hackerspace beat them to it.

One of our core members, Jordan Miller, has just published a scientific paper using RepRap 3D printing technology to engineer living tissues for regenerative medicine. I'll give you a rundown of the science and a step-by-step guide of how Jordan got to this great spot in his career. Jordan is quick to point out that this is work that would not have been possible 5 years ago, or without the help of RepRap, Hive76, and this wonderful city of Philadelphia.
I smiled a little at the repeated warnings that sugar melts in water and under heat. Is the assumption that engineers don't know the properties of common cooking ingredients? Note: Unless you work for the design firm of Hansel & Gretel and build gingerbread houses for wicked witches, DO NOT use sugar in load-bearing structures! :)
