The Refabricator system by the US-based aerospace company Tethers Unlimited Inc. (TUI) has been installed on the International Space Station (ISS). The integrated 3D printer and plastic recycler was launched into space in November last year.
The CEO of TUI Rob Hoyt said that he was “incredibly proud and thankful for the hard work put in by our team, the astronauts, and the NASA In Space Manufacturing Team to get the Refabricator all the way to installation aboard the space station.”
It may sound like science fiction but the beauty industry is experiencing a makeover and for the first time it’s not at the expense of animals
Back in 2015, L’Oréal announced that it was experimenting with printing human skin tissue on which to test its cosmetics. The French beauty giant – which owns Lancôme and Maybelline, among many others – was the first beauty conglomerate to announce such intentions. The same year, L’Oréal partnered with Organovo, a San Diego-based start-up that designs and creates functional human tissues using bioprinting technology. These 3D printed tissues, which Bloomberg predicts could be a reality by 2020, mimic the form and function of native tissue in the body and testing on them could signal a revolution in the world of cosmetic testing. ‘‘What was once a plot for a science fiction novel is now advancing our scientific research,’’ Taylor Crouch, Organovo’s CEO said to the Financial Times last year.
There are two types of skin tissues that can be created by bioprinting technology, according to Joshua Zeichner, a dermatologist and the director of cosmetic and clinical research in dermatology at New York’s Mount Sinai Hospital. One type of skin tissue is developed with an individual’s own cells and it can be used to treat burns or skin conditions that the subject may have. The second is a regular skin formed using a stock of genetic human cells. Here cells are taken from donor organs and plastic surgery leftovers and then turned into a printable bio-ink. It is this second type of tissue that could one day make animal testing obsolete.
MCAS Iwakuni engineers have devised two products that reduce the time it takes to repair the fighter jets, saving costs for the U.S. Department of Defense. The products help with the maintenance, repair and overhaul (MRO) of the fighter jets, covering all tasks carried out to ensure the airworthiness of an flight vehicle.
The 3D printed products include an engine ship kit, designed by the Marine Aviation Logistics Squadron 12 (MALS 12), and a plastic ring kit that helps the maintenance of the bearings on the F/A-18’s Gatling gun.
In 2015, market research firm Gartner projected that medical 3D printing would become the pioneering field that would drive additive manufacturing (AM) into the mainstream in two to five years. Four years have passed, so we’ve decided to examine the industry to determine if Gartner’s predictions have come true.
In this article, we’ll explore a handful of medical 3D printing stories from the past year to gain perspective on the level of adoption at which the technology stands.
While additive manufacturing has received attention for its promise of mass customization and generative design, not everyone believes it’s ready for large-quantity production.
3D Printing is revolutionizing design and customization. It has become the go-to process for prototyping. As an additive manufacturing (AM) process, 3D printing has proved effective in many applications in Aerospace and Medical, but technical constraints may be holding 3D printing back from become that next manufacturing revolution.
For one, few companies have redesigned their products and supply chains for AM friendliness. “One of the biggest barriers to additive manufacturing is that the way companies utilize the technology doesn’t match what their production requires,” Ken Burns, technical director at Forecast 3D, told Design News. “When opportunities to use additive manufacturing come to the production side, there are so many barriers. You need to do x, y, and z, to make it work, and that affects the price point.”
Aerospace has aggressively embraced 3D printing. The industry seeks parts that are lighter without sacrificing strength, and 3D printing meets that challenge.
The aerospace industry was among the first advocates of 3D printing. The airline industry as well as the space industry have been the force behind the evolution of this technology, both manufacturing end-use parts and for prototyping. Aerospace depends on 3D printing to alleviate supply chain constraints, limit warehouse space, and reduce wasted materials from traditional manufacturing processes. The ability to rapidly produce parts on demand has brought unexpected efficiency to the industry.
Here are some shiny examples of how aerospace has utilized 3D printing.
Additive manufacturing aligns with the needs of the automotive industry, driving advances in vehicle design. Serial production is a reality today in additive manufacturing (or 3-D printing) as the technologies under this umbrella have advanced to a point where end-use parts can be made of both metal and plastic materials, ready to be put to use in real-world environments. The automotive industry has been a major adopter, with automotive OEMs among the first to install 3-D printers — some 30 years ago, in fact, Ford purchased the third 3-D printer ever made.
A 2014 Deloitte study pointed to two major areas of influence for 3-D printing in automotive applications: as a source of product innovation and as a driver of supply chain transformation. Over the past nearly half-decade, these predictions have shown to be spot-on as new vehicle models come out faster and sleeker, with digital supply chains reshaping logistics.
Some of the best-known benefits of additive manufacturing align precisely with what automotive OEMs are looking to deliver: faster development cycles, part consolidation, lightweighting, new and custom geometries.
Manual tests for safe drinking water can be slow and error-prone. A team of academics is trying to change that
Like many people, Alexander Patto was keen to move away from academia after his PhD. He wanted a job that would have a tangible impact on the world, so when an opportunity came up to investigate water testing in the developing world, he jumped at the chance. Together with a team of academics from the University of Cambridge, Patto, a biologist, worked on a simple way of testing bacterial contamination in drinking water.
“The current systems are very slow and complex,” says Patto. To get a robust result “there is a lot of manual sampling”, which can also lead to “a lot of human error”, he says. “What we’re trying to do is make it very, very simple, so that anybody can do a test, regardless of their skillset [and the] resources available, and still get a result that is scientifically robust.”
Recognizing the need for evidence-based recommendations in the sector, these guidelines have been developed over a period of two years, in review of over 500 recent papers published on the topic.
As the abstracts states, “The recommendations provide guidance for approaches and tools in medical 3D printing, from image acquisition, segmentation of the desired anatomy intended for 3D printing, creation of a 3D printable model, and post-processing of 3D printed anatomic models for patient care.”
3D printing technology applications come alive in applications ranging from developing packaging machinery to producing personalized medical devices to printing custom medications in a patient’s home.
The FDA acknowledges that “advances in material science, digital health, 3D printing, as well as other technologies continue to drive an unparalleled period of invention in medical devices.”
The perspective comes from a Nov. 26, 2018 statement by FDA Commissioner Scott Gottlieb and Jeff Shuren, Director of the Center for Devices and Radiological Health, outlining transformative new steps to modernize FDA’s 510(k) program to advance the review of the safety and effectiveness of medical devices.
