Crafty Researchers Cast Blood Vessels Into 3D Printed Replacement Organs
why you cant print that pie chart printer problem somethingofthatilk.com failblog


The interesting intersection between the ‘Old’ and New sciences of Stem Cells and 3D-Printing is starting to provide some amazing developments in both Life-Extension and Replacement-Parts.

The well-known windpipe-replacement is also one of the bigger successes in that category as of late.

 
*However, to make these things Truly Useful, there are still quite a few obstacles to overcome.

-And now, Make that quite a few, -Minus One.

 
Jennifer Lawrence Lewis and her team have come up with quite an ingenious advance to the problem of printing a ‘part’ that has Blood-Vessels.

Their solution, just like the main feature inside your otherwise-unreliable, para-explosive, jet-fuel-expensive, desktop inkjet-printer was brilliant, elegant, and simple:

Several. Different. “Inks”. -BOOM!

 
So the Harvard Team came up with this neat trick:

Make a 3D printer that has several heads, and then use different “inks” for the different regions or material-types of each part they want to create.

-Right now they have 2 inks: one for the structure, and one for the blood-vessels.

 
But wait; There’s more!

Yet another clever turn-of-thought occurred to them: Think Like A Sculptor who does castings.

The “Vessel”-sites of course would have to be +/- Empty Tubes,

So: How do you print something in 3D that’s completely-enclosed, even with 2 “Inks”,

-BUT then later-on have one of those inks go POOF! And Vanish?

I’ll leave that bit of Genius as a little guessing-game exercise for the reader. You can then see if you were right over at the Links:

 
PS: We don’t yet have all the nerves, hair, sweat-glands, skin-pores, adult-acne & pheromones that all the super fancy Sci-Fi movies have,

But make no mistake ladies and germs, the future of modular body-part replacement just got A LOT brighter.

Especially considering our friend in Sweden with the replacement vein.


-And if the Harvard team can pull off this new magic for blood-vessels, how far away can all the other stuff really be?


Check out the Links for those last few tasty morsels of Jennifer Lewis genius!:
