Israeli Firm Develops 3D Printer Ink That Can Synthesize Human Tissue From Stem Cells – TheTower.org

It is the stuff of science fiction: innovation that can print a human organ. But the initially step towards turning big-screen fantasy into day to day reality has been taken by an Israeli 3D printing company, Nano Dimension.
Through a collaboration with another Israeli company, bioinnovation firm Accellta of Haifa, Nano Dimension has been able-bodied to mix human stem cells into its 3D printing device ink. When expelled through the additional than 1,000 tiny nozzles of a Nano Dimension DragonFly 3D printing device, the ink can form into human tissue.
Whilst the innovation is yet at the proof-of-concept stage—and going of easy tissue to a full organ is a daunting and uncharted system—the possibilities for saving lives by “printing” a new liver or lung are staggering.
CEO Amit Dror stressed that Nano Dimension is not the just company to contribute biotech printing. The difference is the speed and print resolution.
“No one else is via inkjet innovation,” Dror told ISRAEL21c. “We’re the initially to do it quite swift and quite accurately.”
Before Nano Dimensions teamed up with Accellta, printing actually a quite tiny tissue may take a whole day under careful lab conditions, and was utilized mainly for research.
“We showed how the same thing can be achieved in a few seconds,” Dror explained. “That means this may actuallytually go into commercial use”—such as in a hospital during emergency surgery or for testing new pharmaceuticals on living tissue.
Nano Dimension’s breakthrough is a certainly serendipitous detour of its main business, that is printing PCBs—the printed circuit boards that go into equitething of cell phones to smart refrigerators. As its name suggestions, Nano Dimension uses nanoinnovation to print the metal part of a circuit board via “ink” in that tiny silver particles are suspended.
Silver melts at a temperature of 1,763 degrees Fahrenheit—much too hot for a printing device—but when it’s taken down to the nano level, it can stay liquefied between around 200 and 400 degrees, Dror said. Once it’s printed, the silver cools down and the PCB is eager.
3D-printed PCBs most likely aren’t in your laptop desktop. “It is not for weight market production but additional for prototyping,” Dror explained. Nano Dimension is the just 3D printing device company in these days that focuses on PCB production.
Dror has frequently turned down proposals of future partners wanting to collaborate on various types of types of projects beyond PCBs. “We haven’t wanted to get defocutilized,” he said. But Accellta was various.
“We’re certainly great at creating and reproducing stem cells,” Accellta CEO Itzchak Angel told Dror. “But we don’t have the innovation to allocate the cells into a tissue. For that we require a printing device.”
Dror felt the two companies were complementary. “We’ve created a quite great belief of chemistry,” Dror said. “It is not trivial to take nanomaterials and print them accurately.”
Accellta and Nano Dimensions worked together for several months on the tricky system. “We had to manufacture certain we didn’t electrify and kill the stem cells when the inkjet is spitting them out,” Dror said. “We actuallytually created a whole new set of bio-inks.”
Different bio-inks carry various types of cells. A third type of ink that does not include stem cells solidifies the outcome. “After all, you don’t want a pulp of ingredients, but a structure that looks like a tissue,” Dror said. After the tissue is printed, it’s sent to Accellta for incubation.
Nano Dimension’s stock price soared 17 percent on the day it revealed its stem-cell printing collaboration with Accellta. The company has in addition filed a patent application for its method.
Whilst 3D bio printing is a “quite hot topic,” Dror said, Nano Dimension is not giving up on its PCB business. At the end of Q1 2016, the public company had $7.6 million in the bank, and can soon begin rolling out its initially commercial 3D printing devices for PCB production.
Dror may spend his days considering of 3D printing devices and stem cells, but at night, he can kick back with a locally brewed whiskey. Along with Nano Dimension chief business officer Simon Fried, Dror cofounded Tel Aviv’s Milk and Honey Diyetery, that manufactures bourbon and rye-based whiskies, and in 2018 can release Israel’s initially kosher single malt as a special bonus exclusively for supporters of Milk and Honey’s Indiegogo crowdfunding campaign.
The rest of us can have to wait a bit longer—unless, of course, Nano Dimension begins printing whiskey as the following evolution of its 3D expertise.
