“Our digital manufacturing partners are working non-stop in the battle against this unprecedented virus.”
Additive manufacturing, or 3D Printing has long been trumpeted as the lodestar of a “Fourth Revolution”. In reality, uptake has been limited, it remains somewhat niche, and hype has not met market expectations. Yet as the world grapples with the COVID-19 pandemic, the 3D printing industry and hobbyists alike are stepping up to help ease the supply chain disruptions by creating and printing urgently needed components.
The major issue for healthcare workers at the moment is the overwhelming numbers of people that are in urgent need of oxygenation; requiring ventilators so they can breathe long enough for their immune system to fight off the worst of the virus.
Prior to COVID-19, 3D printing was most commonly, “used in manufacturing lines or during research and development and prototyping for any sort of device, medical or otherwise. One of the more popular ones are dental aligners. Even companies as large as Invisalign or a Smile Direct Club are using 3D printing to print those aligners,” said Guarav Manchada, director of healthcare at Formlabs, a 3D printing company.
However, the coronavirus is elevating the popularity of 3D printers, bringing them to the forefront of the public’s mind.
3D printing specialist Stratasys is aiming to produce 5,000 disposable face shields in the US alone by the end of this week (March 27) in the fight against the Covid-19 coronavirus.
The PPE equipment for medical personnel consists of a 3D printed plastic frame and a clear plastic shield that guards the entire face of the wearer, under which particulate face masks are usually worn for additional protection. One leading hospital informed Stratasys that it uses more than 1,500 of the face shields over the course of a regular week. The Covid-19 outbreak had reduced the hospital to just six days’ inventory of the equipment.
Aircraft part manufacturer Satair is using HP’s full colour 3D printing technology via service provider Fast Radius to produce redesigned tooling components.
The Airbus services company moved to adopt Fast Radius’ 3D printing capabilities in a bid to increase the speed and sustainability of aircraft maintenance tool delivery. Working with both Fast Radius and HP, Satair has additively manufactured GAGS tool pads, flap zero locking tools and pintle bearing alignment tools, all of which are industry compliant.
Using the HP Jet Fusion 580 Color platform, these tools were printed in a PA 12 material, to take advantage of its chemical resistance to oils, greases, aliphatic hydrocarbons and alkalis, and in red and orange colours, to enhance their visibility. The GAGS tool pads have a reduced mass of 60% and an improved strength-to-weight ratio; the flap zero locking tools have been reduced from six assembled components to two, with its lead time halved; and the pintle bearing alignment tools have been reduced from four parts to two.
Two Joint Innovation Projects (JIPs) seeking to establish guidelines for the production and qualification of additive manufactured parts for the oil and gas and maritime industries, has concluded.
The JIPs, organized by DNV GL, an international accredited registrar and classification society, and comprised of 20 different partners, involved 2 years of intensive work and discussion. Some of the firms involved include BP, Shell, Total, Siemens, SLM Solutions, Sandvik, Additive Industries and more. Their goal was to develop guidelines to help qualify parts produced by Laser Powder Bed Fusion (LPBF) and Wire Arc Additive Manufacturing (WAAM) processes. The partners also sought to create an accompanying economic model, to be used in the oil and gas and maritime industries.
While synthesising meals on demand may seem like something out of a futuristic movie, 3D printing could soon become a regular way of processing food.
Tatjana Milenovic, Global Head of ABB’s Food and Beverage Segment, explains how 3D printing could change the way we manufacture food.
The ability to 3D-print food isn’t a huge intuitive leap. After all, we’ve already successfully created medical devices, machine tools and even entire homes using additive manufacturing technology.
In 2006, NASA (National Aeronautics and Space Administration) began researching 3D-printed food and developed the NASA Advanced Food Programme seven years later, with the mission of feeding astronauts for extended periods of time.
Award-winning desktop 3D printer provider Ultimaker has announced that ERIKS, an international industrial equipment supplier, has scaled up its 3D printing capabilities for OEM and MRO customers using Ultimaker 3D printers.
At its production facilities in Alkmaar, The Netherlands, ERIKS has installed multiple Ultimaker S5 Pro 3D printer bundles. Leveraging the systems, the company has provided its customers with support in identifying, designing and printing applications. With a focus on co-engineering, the company has been able to 3D print parts alongside its customers according to specific industry standards, especially in regards to food safety and cleanliness.
Such a process, Ultimaker claims, has made it easier for professionals working in MRO and OEM industries to adopt 3D printing technology. Jos Burger, CEO at Ultimaker, explains: “As shown in the 3D Printing Sentiment Index, only 35 percent of companies have adopted additive manufacturing, while in many industries worldwide margins are currently under high pressure. Efficiency is key to bring a competitive edge and 3D printing plays a major role in this, as ERIKS experienced first-hand with achieving their impressive cost-and time savings.”
ZAL Tech Center played host to this year’s Red Cabin Aircraft Cabin AM Conference.
I’ve said it before, since working in additive manufacturing I’ve adopted a bit of a habit of playing “spot the additive application” whenever I board a plane. Great for editorial, but quite annoying, I would imagine, for my other half whenever we go on holiday.
The same happened last week as I hopped on a flight to Hamburg for the second Red Cabin Aircraft Cabin Additive Manufacturing conference. As I settled into the brash yellow and blue my seats of my budget aircraft (the glamorous life of the media), I began circling with imaginary red pen all of the areas where AM might find a useful home from the tens of assembled parts I could see in the arm rest mechanism to the unnecessary tray tables that had been bolted shut to restrict use in the rows of emergency exit seats (it’s really almost TOO glamorous).
Two ferry rides later, it was exactly those types of applications that a collective of aerospace specialists and additive experts had gathered at the ZAL Tech Center, south of the River Elbe, to explore. If being privy to two days worth of brain storming sessions with a bunch of 3D printing-literate engineers shows you anything, it’s that those far flung ideas like personalised seats and bionic bathrooms are not a million miles away from reality. Though the suggestion of a real-life RoboCop may be taking things a little too far.
Having previously utilized Stratasys’ 3D printing systems to fabricate spare parts for the German and UK rail industries, Siemens Mobility Services has increased its investment in Stratasys’ 3D printing technology to expand its rail maintenance operation in Russia.
Two new industrial-grade Stratasys Fortus 450mc 3D printers will be used for spare part production to support the 13 additional high-speed Velaro trains Siemens Mobility will be building for Russian train company RZD.
The 30 year maintenance project
The 13 new trains will be added to an existing fleet of 16, with a 30 year agreement to maintain and service the trains also in the deal. This third Velaro order from RZD will bring the total number of high-speed trains to 29.
Having successfully implemented Stratasys‘ 3D printing to produce parts for the German and UK rail industries, Siemens Mobility Services has continued its investment in Stratasys technology to support the expansion of its rail maintenance operations in Russia. This includes two new industrial-grade Stratasys Fortus 450mc 3D Printers for part production.
The decision comes in line with a recent business win for Siemens Mobility to build 13 additional high-speed Velaro trains for Russian train company, RZD, including an agreement to maintain and service the trains for the next 30 years. This is already the third Velaro order from RZD for Sapsan fleet due to excellent availability of Sapsan trains in daily operation, supplementing an existing fleet of 16 trains.
