Finding the new limits of AM (Authentise Weekly News-In-Review – Week 88)

If you think that AM is sitting comfortably into its allotted seat, that it has already found its target market, you’d be wrong. AM’s flexibility enables us to find numerous potential fields to disrupt. This flexibility is made possible by its assortment of technologies, hardware, software and everything in between, that change the rules year by year. Advances in robotics and AI enable groups of autonomous, mobile units to step up the construction process. After the 3D printed pills and surgical models and implants, we are now beginning to use AM in the development of new future-proof antibiotics. Strong of its success of sending the first 3D printer to the ISS, Made in Space is aiming to produce higher quality fiber optics in space, creating a new business case for manufacturing in and outside Earth’s orbit.

Mobile Robots Cooperate to 3D Print Large Structures

A team of robot arms on mobile bases can 3D print large structures quickly

Roboticists at Nanyang Technological University in Singapore have, for the first time (as far as they know), performed “the actual printing of a single-piece concrete structure by two mobile robots operating concurrently.” The big advantage of this system is that you can use it to build structures that are more or less arbitrary in size without having to change the system all that much, since the robots themselves can define their own build volume by moving around.

AM thermoplastics can (and will) compete with metal counterparts (Authentise Weekly News-In-Review – Week 73)

Do you think that metal AM is the apex of mechanical performance we can achieve? There are many cases in which the humble thermoplastics are poised to match, and surpass, the benefits of metal-based AM techniques. Consider this: metal AM is still mostly happening thanks to high-powered lasers shone onto a powder source. This technique, and the powder preparation, is very resource intensive operation. With thermoplastics, on the other hand, you’ll seldom go above the 300°C mark. That doesn’t mean that you’d have to sacrifice in terms of performance. Arevo has shown through a bicycle frame that materials like PEEK can rival titanium in mechanical strength, showing a lot of promise in various fields. Research is also ongoing for new materials that offer a more flexible range of features, depending on the use case. AM lets us control these materials to allow for designs that exploit their natural properties in new and exciting ways.

International Consortium Delivers New Microgravity 3D Printer Prototype to European Space Agency

Over two years ago, the European Space Agency (ESA), looking to further develop its ability to manufacture and prototype new technology in outer space, set up a small consortium of European companies to create an advanced Additive Layer Manufacturing (ALM) breadboard machine. The consortium was formed by the agency’s Manufacturing of Experimental Layer Technology (MELT) project, which aims to explore, design, build, and test a fully functional 3D printer that can work in the microgravity conditions of the ISS.

3D-printed thermoplastic bicycle shows promise to replace titanium

This bicycle was made in a 3D printer.

[The Arevo bicycle] is being hailed as the first truly 3D-printed bicycle. The bicycle frame was made in one piece and eventually, other parts of the bicycle could be printed, as well. It took about two weeks to build the bike — which is a lot quicker than the usual labor-intensive method of piecing together carbon fiber strips. [CEO Jim Miller] was also excited about the material that’s stronger than titanium and really hard to break. It’s also recyclable and made from non-toxic materials, which seemed like important points to Miller. He noted that the frame uses the same material, polyether ether ketone, known as a PEEK polymer, used in spinal replacements.

Biomimicry in 3D printing

rotational 3D printing

Researchers at SEAS, Cambridge have come up with a new 3D printing method inspired by natural composites. The idea was to achieve the best arrangement of short fibers at each location of the part being printed.

“Being able to locally control fiber orientation within engineered composites has been a grand challenge,” says Jennifer A. Lewis, senior author of the study and Hansjorg Wyss Professor of Biologically Inspired Engineering at Harvard SEAS. “We can now pattern materials in a hierarchical manner, akin to the way that nature builds.”

AM, bringing In-Situ manufacturing to a facility near you! (Authentise Weekly News-In-Review – Week 24)

In the comfort of our daily lives, we often take for granted some of the services and perks of our industrious world. We are getting really good at managing the complex scenarios of a global economy where any kind of goods must be shipped and handled efficiently but, still, it’s driving a decisive cost factor in every business. Logistics is inherently complicated but, with AM decentralizing manufacturing capabilities, this is about to change, drastically. In-situ manufacturing is a game-changer in a wide variety of cases. Bespoke replacement parts, like Daimler is doing with its buses, can be produced as needed, driving down storage and production expenses. The Australian DOD is developing a program to deploy 3D printing on the front lines, vastly improving the base’s flexibility in addressing its needs. It goes as far as the ISS, where astronauts will 3D print habitat’s radiation shields through it’s on-board AM device, saving millions on resupply launches.

Enabling Research Through AM (Authentise Weekly News-In-Review – Week 01)

Hi everyone, welcome back to the new year with a more weekly 3D printing news from Authentise!

Through AM scientists are able to go where traditional manufacturing simply couldn’t take them. NASA is keeping up the pace for the entirely 3D printed rocket by testing more and more components up for the challenge, ROSCOSMOS is planning to add a bioprinter to the ISS’s arsenal and test it at microgravity and, while we’re at it, stem cell research is getting a boost from 3D printing’s ability to create cartilage’s structures.

Are you aching for your daily fix of science with a side of AM? Let’s dig in.

NASA Engineers Test Combustion Chamber to Advance 3-D Printed Rocket Engine Design

Recent tests of a developmental rocket engine at NASA‘s Marshall Space Flight Center in Huntsville, Alabama, produced all the performance data engineers were hoping for, along with the traditional fire and roar. But this engine is anything but traditional. Marshall engineers are designing each of the components from scratch to ultimately be made entirely by AM methods …The series of 12 test firings in late fall brought them a big step closer to that goal, said Andrew Hanks, test lead for the project. The fuel turbopump, fuel injector, valves and other major engine components used in the tests were 3D printed, with the exception of the main combustion chamber.

Scientists Are Creating New Ears With 3D-Printing and Human Stem Cells

BNWM3H.jpg

Inspired by the earmouse, doctors at the University of California at Los Angeles and the University of Edinburgh’s Centre for Regenerative Medicine have perfected a new technique to grow a fully formed human ear, using patients’ own stem cells. They begin with a 3D printed polymer mold of an ear, which is then implanted with stem cells drawn from fat. As these stem cells differentiate into cartilage, the polymer scaffold degrades, leaving a full “ear” made of mature cartilage cells. The new approach could “change all aspects of surgical care,” says Dr. Ken Stewart, one of the researchers and a plastic surgeon at the Royal Hospital for Sick Children.
