How 3D Printing Can Build New Bone

FReepmail me if you want on or off my stem cell/regenerative medicine ping list.

Gives new meaning to the words ‘plastic surgeon’.

Wonder if they can print breasts and male organs ?

When will we be able to print a person ?

"Bannock says that for chemists, an off-the-shelf 3D printer has limited use. ‘Most of the materials are not tolerant to any organics,’ he says, adding that there is a need to move to polytetrafluoroethylene derivatives. ‘I’ve contacted the major companies that make the printers but none seem to have tried this, despite the starting materials being widely available,’ says Bannock. He says that the investment companies would need to make is putting them off.

Actually, the printers to handle this are already available in the "open source" world. They are the "photopolymerization" type that print layers on exposure to a flash of light. These printers use the internals of a DLP projector.

There is also a photopolymerizable monomer that has the needed properties to yield a Teflon-like material. The problem is that said monomer is not commercially/inexpensively available. "Somewhere" on my desk I have a paper detailing the synthesis of the monomer. If I can locate it, I'll post the reference.
