Artificial Blood Vessels Created On a 3D Printer 33
rallymatte writes "A team at Fraunhofer Institute in Germany has managed to create artificial blood vessels with a 3D printer that may come to be used for transplants of lab-created organs. From the article: 'To print something as small and complex as a blood vessel, the scientists combined the 3D printing technology with two-photon polymerisation — shining intense laser beams onto the material to stimulate the molecules in a very small focus point.'"

What a headline (Score:1)
.. and with such headlines, the population gets convinced that we got Star Trek technology standing by.
No wonder why half the population thinks that astronaut training takes places in "antigravity chambers".

Blood vessel != blood cell. Or is that the joke?
The headline doesn't exaggerate. They need to make artificial capillaries for synthetic tissue, and now they've come up with a way to make them. It'll be years before this will have progressed far enough to be an actual product (let alone one that is routinely used on human patients), but that's how all research works.

because the only thing more expensive than ink toner is human blood [boingboing.net]. oh wait...

The phrase "ink toner" is a contradiction in terms, making about as much logical sense as the notion of "dead survivors".
Because toner is *NOT* ink.
Ink is a liquid pigment, toner is dry.
Ink is simply absorbed into the substrate of whatever surface it is put upon, where toner is bonded to a surface through application of heat and pressure.

I think the anonymous poster was going for humor on this. I laughed. Just food for thought.
Ew... bad mental image. (Score:4, Funny)
All of a sudden I had this image of printing kidneys, blood vessels and all, shooting out of a laser printer because someone clicked the wrong application.

In two-photon polymerisation, you start with light of, say, 800nm, and you rely on two photons being absorbed at the same time, which together have enough energy to do wha

Artificial trachea implanted back in June (Score:2)

So the fellow in Stockholm, who's name is Paolo Macchiarini, decided to try, first time - he thought the time was ripe to try an experiment in which they would take a scan of his trachea to make sure they had the exact dimensions. A fellow in London has invented this spongy plastic. It's porous. Make a model of his trachea that's exactly the right size. Meanwhile, a company in Massachusetts was making an incubator.

Now we just need to see how the outcome turns out.
