ALL THAT AND CURTAIN RINGS?

Bones from the 3D-printer (Deutsche-Welle, 3/25/15)

3D-printers can print just about anything these days: shoes, guns - and even bones. Scientists all over the world have been working on printing bone replacements for some time. Now researchers at the University of Freiburg in southern Germany are taking a major step forward. They want to use a 3D-printer to create bones that come complete with blood vessels. With this method chances are higher that the print-outs connect to the surrounding tissue faster.

"This should make a crucial difference timing-wise," G√ľnter Finkenzeller, head of the Tissue Engineering Department at the Plastic- and Hand-surgery center at the University of Freiburg, told DW. "Then the printed blood vessels only need to connect with the other vessels directly bordering on the implant and the natural tissue."

Other methods well documented in medical literature require blood vessels to grow into the implant from the surrounding tissue, which can take up to two weeks. By then, many artificial bones would have died off.
