3D-printing is everywhere these days. Earlier this year, General Electric Co. announced that they are developing a 3D-printer for jet engine parts. It will be the largest of its kind. The printer works by fusing thin layers of powdered metal with a laser. At the other extreme, medical researchers are working hard to print body parts. A recent article in The Guardian asks if bioprinting could provide organs for transplants. Organ shortages lead to hundreds of thousands of deaths every year.
Meat, of course, is a body part and scientists are printing that too. Gabor Forgacs of the University of Missouri works on organ printing. He also jointly holds a patent for engineered comestible meat. The idea is to print layers of living cells on a scaffold and culture the result. The cells will fuse to form muscle tissue, also known as meat.
The patent applies the modifier non-human whenever cells are mentioned. Although engineered meat may be an option for vegetarians, it doesn’t seem to hold out hope for cannibals. [Read more…] about Boosting the bug content of chocolate using 3D-printing
