NASA installs Tether Refabricator aboard ISS for in-space 3D printing

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.

Will 3D printed human skin make animal testing for cosmetics obsolete?

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

Damien Hirst

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.

At the U.S. Marine Corps Air Station (MCAS) Iwakuni, southern Japan, 3D printing is now in use to keep F/A-18 Hornet multirole fighters airborne.

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.

Medical 3D Printing: Where Are We Now?

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.

Is 3D printing ready for scaled production?

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.”

3D Printing takes off in Aerospace

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.

The retail supply chain: has technology advanced the process?

The world of retail appears to be more reliant on technology to survive. But how has it affected the supply chain specifically? Read on as we explore how technology has transformed and helped businesses maximise their supply chain efficiency, including making deliveries speedier and keeping up with fluctuating consumer demands.

Consumer demand

Retail

Apparently, consumers are getting more demanding, which has caused companies to react if they want to retain and attract customers. Many consumers expect convenience now that they know it’s possible. When they’ve received one service from a business, the bar is raised, and they expect that all their other favourite brands will do the same.

Tracking a package throughout its entire journey and getting the item you purchased last night the next day is no longer a luxury in retail for many customers. For businesses, this means that an efficient supply chain with a well-managed inventory tracking system is essential. And, when it comes to getting in touch with the business, customers expect instant contact through the channels that they’re most used to — Twitter, Facebook and instant messaging platforms.

Additive manufacturing is driving the future of the automotive industry

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.

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.

Medical 3D printing companies gain FDA certification under Materialise program

If you follow 3D printing or medical news at all, you’re likely familiar with the many ways that 3D printing is changing medicine for the better. 3D printed anatomical models are helping surgeons better plan and execute surgeries, while 3D printed implants are being customized to patients for better comfort and longevity, just to name a couple of the major advancements of 3D printing in healthcare. While it may seem like things are happening quickly, however, the solutions don’t just appear and magically change the world; there are hurdles that must be addressed before these solutions can be truly widespread, particularly the dreaded R word – regulation.

In March last year, Materialise became the first company to receive FDA clearance for diagnostic use of its 3D printed anatomical model software. The company then launched an FDA-approved certification program that allows 3D printer manufacturers to have their products tested and validated for use with Materialise’s Mimics inPrint software, which converts medical images into 3D print-ready files.
