A 3D-printed prosthetic hand controlled using a new AI-based approach could significantly lower the cost of bionic limbs for amputees.

Real need: There are approximately 540,000 upper-limb amputees in the United States, but sophisticated “myoelectric” prosthetics, controlled by muscle contractions, are still very expensive. Such devices cost between $25,000 and $75,000 (not including maintenance and repair), and they can be difficult to use because it is hard for software to distinguish between different muscle flexes.

Handy invention: Researchers in Japan came up with a cheaper, smarter myoelectric device. Their five-fingered, 3D-printed hand is controlled using a neural network trained to recognize combined signals—or, as they call them, “muscle synergies.” Details of the bionic hand are published today in the journal Science Robotics.

New 3D-printed materials are going to space thanks to a recently funded partnership between Israel’s NanoDimension and Florida’s Harris Corp.

The companies plan to create new materials to reduce the manufacturing of small satellites, an exceedingly popular market right now for applications ranging from weather observations to remote surveillance.

They aim to fly their materials on an external platform of the International Space Station for a year. The goal is to better understand how 3D-printed components (such as circuits and materials) withstand the space environment, which includes extreme temperature swings and high radiation. The launch date of the project was not disclosed.

An exciting breakthrough from Columbia University researchers demonstrates a new way to grow human hair follicles using 3D printed molds. This is the first time human hair follicle cells have been grown completely in lab conditions, opening up a potentially unlimited source of hair follicles for future hair restoration surgical procedures.

On a sofa in the corner of the room, a cat is purring. It seems obvious that the cat is an example of life, whereas the sofa itself is not. But should we trust our intuition? Consider this: Isaac Newton assumed a universal time flowing without external influence, and relative time measured by clocks – just as our perception tells us. Two centuries later, Albert Einstein dropped the concept of universal time, and instead introduced a concept of time measured only locally by clocks. Who before Einstein would have thought that time on the Sun, the Moon, and even on each of our watches runs at slightly different rates – that time is not a universal absolute? And yet today our cellphones must take this into account for a GPS to function.

Life ≠ alive.

A cat is alive, a sofa is not: that much we know. But a sofa is also part of life. Information theory tells us why.

Though it may be hard to believe that there is already an “established” method of doing something such as 3D-printing biological tissue, there does indeed seem to be one. It utilizes microscale scaffolds – which a newly-developed technique does away with the need for.

Adam Savage has made bullet-proof Iron Man Armor using 3D printed titanium and a flying jet suit from Gravity.

It is more precisely a real-life Titanium Man (comic book enemy of Iron Man).

New LulzBot bioprinting hardware coming 2019 with long term goal of printing real functional tissues.

Kyle Reese: The Terminator’s an infiltration unit, part man, part machine. Underneath, it’s a hyperalloy combat chassis — micro processor-controlled, fully armored. Very tough. But outside, it’s living human tissue — flesh, skin, hair, blood, grown for the cyborgs…

3D bioprinting is the automated fabrication of multicellular tissue via spatially defined deposition of cells. The ability to spatially control deposition in the x, y and z axes allows for creation of tissue-specific patterns or compartments, with in vivo-like architecture that mimics key aspects of native biology.

3D bioprinted tissues exhibit a microenvironment more suited to in vivo-like cellular function in comparison to traditional 2D monoculture (or monolayer co-cultures), as well as maintenance of a more defined architecture than is observed in self-aggregated co-culture models.
