NASA, Made in Space think big with Archinaut, a robotic 3D printing demo bound for ISS

MOFFETT FIELD, California — Within five years, companies could begin in-orbit manufacturing and assembly of communications satellite reflectors or other large structures, according to Made in Space, the Silicon Valley startup that sent the first 3D printer to the International Space Station in 2014.

As Made in Space prepares to send a second 3D printer into orbit, the company is beginning work with Northrop Grumman and Oceaneering Space Systems on Archinaut, an ambitious effort to build a 3D printer equipped with a robotic arm that the team plans to install in an external space station pod, under a two-year, $20 million NASA contract. The project will culminate in 2018 with an on-orbit demonstration of Archinaut’s ability to additively manufacture and assemble a large, complex structure, said Andrew Rush, Made in Space president.

NASA’s selected the Archinaut project, officially known as Versatile In-Space Robotic Precision Manufacturing and Assembly System, as part of its Tipping Points campaign, which funds demonstrations of space-related technologies on the verge of offering significant payoffs for government and commercial applications. Archinaut was one of three projects NASA selected in November that focus on robotic manufacturing and assembly of spacecraft and structures in orbit.

3D-printing basic electronic components

UC Berkeley engineers, in collaboration with colleagues at Taiwan’s National Chiao Tung University, have developed a 3D printing process for creating basic electronic components, such as resistors, inductors, capacitors, and integrated wireless electrical sensing systems.

As a test, they printed a wireless “smart cap” for a milk carton that detected signs of spoilage using embedded sensors.

The audacious plan to end hunger with 3D printed food

Anjan Contractor’s 3D food printer might evoke visions of the “replicator” popularized in Star Trek, from which Captain Picard was constantly interrupting himself to order tea. And indeed Contractor’s company, Systems & Materials Research Corporation, just got a six month, $125,000 grant from NASA to create a prototype of his universal food synthesizer.

But Contractor, a mechanical engineer with a background in 3D printing, envisions a much more mundane—and ultimately more important—use for the technology. He sees a day when every kitchen has a 3D printer, and the earth’s 12 billion people feed themselves customized, nutritionally-appropriate meals synthesized one layer at a time, from cartridges of powder and oils they buy at the corner grocery store. Contractor’s vision would mean the end of food waste, because the powder his system will use is shelf-stable for up to 30 years, so that each cartridge, whether it contains sugars, complex carbohydrates, protein or some other basic building block, would be fully exhausted before being returned to the store.

Ubiquitous food synthesizers would also create new ways of producing the basic calories on which we all rely. Since a powder is a powder, the inputs could be anything that contain the right organic molecules. We already know that eating meat is environmentally unsustainable, so why not get all our protein from insects?

Army selects 3D printed unmanned aircraft systems concept for future experiment

ABERDEEN PROVING GROUND, Md. (Feb. 5, 2016) — Each year, the U.S. Army conducts a series of technology demonstrations known as the Army Expeditionary Warrior Experiments, or AEWE. The event is the U.S. Army Training and Doctrine Command’s live, force-on-force experiment.

AEWE places technologies under development by industry and Army researchers into the hands of Soldiers for early and credible feedback from the end-user.

In January, the AEWE 2017 team selected a project submitted by the U.S. Army Research Laboratory for inclusion in its next round of experimentation: On-Demand Small Unmanned Aircraft Systems, or UAS. It is one of 50 technologies slotted to participate in the experiment with 14 from government researchers and 36 from industry.

Scientists Can Now 3D Print Otzi The Mummified Ice Man

Re-creating the Ice Man — 3D Printer Style.

Otzi, for those not up on their 5,300-year-old mummified men, died and was frozen in the Alps near Hauslabjoch on the border between Austria and Italy. His body is one of the best preserved human mummies in Europe and now he’s getting a 3D-printed makeover.

Researchers and engineers have worked together with 3D-printing firm Materialise to perfectly scan Otzi. This allows researchers to 3D print his tortured frame over and over again and, in an interesting episode of Nova, an artist will create a perfect replica of the mummy for study by researchers and potential museum-goers. Otzi, for his part, his hanging out in a climate-controlled vault in Italy so he doesn’t degenerate.

The engineers had to recreate some of Otzi’s parts from scratch, a feat possible thanks to 3D modeling techniques. From the release:

The First 3D Bioprinter That Can Print Body Parts for Large Scale Human Implantation

After 10 years of development, the Wake Forest Institute of Regenerative Medicine has finally unveiled a 3D printer that can craft simple tissues, such as cartilage, into complex shapes suitable for implantation.

The printer uses cartridges filled with biodegradable plastic and human cells bound in gel form, and it can grow muscle, cartilage, and even bone. When implanted into animals, these crafted tissues have been shown to survive and even thrive for an indefinite amount of time.

“This is the first [bioprinter] that can print tissue at the large scales relevant for human implantation,” lead scientist behind the project, Anthony Atala, says in the release. “Basically, once we’ve printed a structure, we can keep it alive for several weeks before we implant it. Now the next step is to test these [printed tissues] for safety so we can implant them in the future in patients.”

This 3D ‘Bioprinter’ Creates Ears, Muscles

A team at Wake Forest University has used a combination of living cells and a special gel to print out living human body parts — including ears, muscles and jawbones.

It’s an advance on previous attempts, which either involved making a plastic scaffold and then trying to get cells to grow in and on it, or that printed out organ shapes that ended up being too floppy and dying.

‘Bioprinter’ creates bespoke lab-grown body parts for transplant

A bioprinter – a three dimensional printer that uses living cells in suspension as its ink, and injection nozzles that can follow a CT scan blueprint – brings the dream of transplant surgery a step nearer: a bespoke body part grown in a laboratory and installed by a robot surgeon.

Scientists and clinicians began exploring tissue culture for transplant surgery more than 20 years ago. But researchers in the US report in Nature Biotechnology that they have harnessed a sophisticated, custom-designed 3D printer to print living muscle, cartilage and bone to repair battlefield injury.

The printed body parts so far have been tested only in laboratory animals. But tested organs have the size, structure and function for human use: once transplanted, they could be colonized by blood vessels and begin to grow and renew themselves normally. The study was backed by the US Armed Forces Institute for Regenerative Medicine.
