honestly had to take a double take when looking into this story. Researchers have developed a bio organ printer that can actually print some organs the way you would print a picture of your kids. This is along the lines or the reprap project that I posted on a while ago. That printer is a 3D printer that can fabricate objects. Anyway, Gabor Forgacs at the University of Missouri-Columbia is leading the effort to create an organ inkjet printer. The result could be genetically manufactured organs that are fast and easy to make that aren’t rejected by the patient’s body.

Forgacs is able to print the organs using bioink and biopaper. The bioink contains cellular material that is ripe for building. The biopaper is a gelatin and hyaluranon mixture that has been altered to set and get harder. This allows them to alternate bioink and biopaper. You can see the process in the picture to the right. The result is the ability to build 3Dorganprint1.jpg organic objects. So far, the team is mostly building smaller things like blood vessels. But they have also built part of a chicken heart that started beating synchronously. The researchers want to be able to build the vasculature right along with the organ. They estimate that they could print a kidney, for instance, in around 20 minutes. The organ would then be put into an environment so that it would grow and mature before transplanting into the patient.

But, could you imagine a time when a new organ could be printed, grown, and implanted within a month? That would save countless lives. And it would be an organ that would be genetically identical to the patient and wouldn’t be rejected. And their vasculature printing would immediately help blood get to the new organ. Most current techniques attempt to promote blood vessel invasion after the fact. Now, where did I put that organ toner cartridge?

I couldn't believe it when a friend told me about this, but it appears to be true. Seems like medicine is going through a genetic revolution even sooner than I thoguht. I wonder what consequences this will have.

3D Printer...? Hmm...this doesn't really sound plausible, but...meh. If this thing works, I think it'll be called a "replicator" instead of a printer. Then you'll soon see human eyeballs, livers, hearts, lungs and kidneys for sale.

Freaky.

[Wizard]

Boy is this a can of worms.......

I am not sure it's realistic any time soon. I imagine that a new cartridge must cost about $40m.

[G-sus]

well i heard some years ago that they were printing skin already, guess it was the same guys.
problem just was, it was about 1cm/week at max.

so like, imagine printing porn..... XD


40 million/cartridge isnt *that* much more than what the original replacements from HP cost...

They've had 3D printers for a while now. I believe it uses a laser to stack molecules layer upon layer, usually ending up with a very accurate wax (or some other material) replica of the original. My collage has one and they use it to print big spacial models of protein as well as some 3D art.

This 3D organ printer stuff just blows my mind, I'm not sure how you can print organs completely. Do they seriously print it all, cells and all? That's incomprehensibly complex. I'm more under the impression that this prints cartilage or some other organic base where they could genetically grow an organ from. But an entire organ? That's incredible.

Thats gotta be bullshit, I can smell it a mile away. We're pretty advanced but this isnt star trek the next generation

[Wi-Ta]

If this would be true then Pandora`s box would be wide open.

[Sgt. Rho]

Well, this is no bullshit actually. The only real trouble will be holding the cells together.

[WNxMastrefubu]

this could revolutionize alot of things...

Its far out, and I think the article is a little optimistic on its development, but theres actually been a lot of success in the field as of late.

Three-dimensional printers are very much reality, and the rapid prototyping they enable is revolutionising the design process. To extend this to print cells in specific patterns would be ambitious, but far from impossible. The problem is sourcing the cells; this device would not be possible without stem cell cultivation. Constructing a working organ obviously poses far greater problems than simply depositing them in the correct pattern, but the fundamentals have been proven, and there's no reason to treat it as a joke. I don't expect to see it in a hospital near me for a long while yet - but remember that if an idea is crazy science fiction, it's often not too long until you see it on the television or the shelves.
If and when something like this becomes available, then it would completely change the organ transplant business. It might take a long time to become economical, but a fix to one of the greatest failures of the modern medical system might just be within reach. In the mean-time I hope to have them introduce an opt-out rather than opt-in organ donation system, but this would be most ideal of all.

There is a political issue with that which I'll go into with you over MSN.

On the other hand having readily reproducible organs would be very useful.

This was idea was stolen from a Discover Channel special called 2057. I remember them mentioning something about an organ printer.

[Sgt. Rho]

Now that you mention it, Yeah, I've seen it there too.
