The push toward going all-in on EVs creates a natural pivot point to leverage industrial 3D printing, also known as additive manufacturing.
In the past year, we’ve seen a drastic shift across the automotive industry and among consumers with a growing appetite for electric vehicles.
General Motors, Ford and other OEMs have made recent announcements signaling they’re pursuing EVs more heavily. President Biden signed an executive order requiring the replacement of the entire fleet of federal vehicles, about 645,000 cars, trucks, and vans, with U.S.-made electrics.
This push toward going all-in on EVs creates a natural pivot point to leverage industrial 3D printing, also known as additive manufacturing (AM). Here’s why:
Relativity Space has the audacious goal of 3D printing 95 percent of a rocket and sending it to orbit. Getting to space is hard. But completely reinventing how rockets are manufactured at the same time? Harder. Six-year-old upstart Relativity may nail both by the end of this year.
After several years designing, building, and testing their Terran 1 rocket, they’re nearly ready to roll. This week the company gave Ars Technica a progress report—and included a pretty visual.
DNV GL, a global certification and risk management firm, has released a new 3D printing service specification document aimed at supporting additive manufacturing in the oil and gas industry.
Specification DNVGL-SE-0568 defines DNV’s additive manufacturing qualification scheme and provides details on how to obtain and retain a number of the company’s 3D printing-related certificates. This includes certificates that endorse facilities and digital manufacturing services, and certificates that qualify manufacturers, build processes, 3D printers, parts, and personnel.
The document was developed in accordance with industry standard DNVGL-ST-B203, which DNV previously created for metallic components in the energy sector. As such, the specification is ultimately intended to help the industry in adopting metal 3D printing in a safe and efficient manner.
The maritime sector is one of the more overlooked segments in 3D printing, with only a handful of companies really taking advantage of the opportunities there. A new business involved in 3D printing for naval uses has made itself known, Austal Australia, who, along with its partners, AML3D (ASX:AML) and Western Australia’s Curtin University, has 3D printed an aluminum personnel recovery davit. The device has been verified by DNV, the world’s largest classification society at its Global Additive Manufacturing Technology Centre of Excellence in Singapore.
According to international and naval specifications, Austal, AML3D and Curtin University produced a three-meter-long crane, also known as a davit, designed for personnel recovery. The assembly was then tested to support over two times its intended working load. This was followed by non-destructive and destructive testing. The testing process included microanalysis of the microstructure of the aluminum parts, with mechanical and corrosion properties compared to those of traditional marine grade materials.
As the technology scales up, it’s being tasked with providing robust new solutions—but it’s also running into some of the same old building problems
It seems that every few months the architecture world marvels at the latest 3D-printed prototype or art installation and wonders at the future possibilities. But to a surprising extent, the future is already here. Companies worldwide are automating the construction of homes, offices, and other structures through techniques like 3D printing, robotic finishing, and automated bricklaying. And as more join this club—and governments and investors ramp up their support—the possibility of automation soon becoming the norm in construction is not so farfetched, addressing construction efficiency, sustainability, and even labor and housing shortages.
“3D printing [on a wide scale] is a lot closer than I thought,” notes Eric Holt, assistant professor at the Franklin L. Burns School of Real Estate and Construction Management at the University of Denver. “I used to believe it was at least five years out, but the ball has moved really quickly.”
“…Utilising 3D printing for the Eutelsat Hotbird satellites provides major labour savings and significantly reduces the number of individual required parts, according to Gareth Penlington, the Hotbird payload manager at Airbus: “This is recognised as the first large-scale deployment of RF products using the ALM process, and it puts us in an industry-leading position for the technology’s application in producing radio frequency components.”
With new capacities, faster speeds, digitalized inventory, and innovative materials, additive manufacturing is moving inventory closer to the customer and forever changing global supply chains.
A new year brings great promise for inspiration and change. We need both of these ideas to move forward in 2021. Our 3D printing community came to the rescue during 2020 to keep our healthcare workers safe dealing with parts of a broken supply chain. The question now becomes: How do we take these lessons and move forward? Let’s talk about:
What we learned about 3D printing’s role in the supply chain in 2020
How 3D printing will evolve in 2021
The impact of 3D printing on supply chains in 2021 and beyond
“AM technology increases the flexibility of manufacturing and production processes, reducing both our dependence on global supply chains and logistics expenses.”
The COVID-19 virus has affected the world in an unprecedented way. The pandemic has shown us just how deeply a crisis can disrupt societies and economies that are now so interconnected on a global level. This has been especially true in the case of supply chains and production. But the situation is also creating some valuable learnings, an important one being that by embracing alternative technologies to innovate, and with industry collaboration, we can make our supply chains more reliable, cost-effective and efficient – not just now but for the longer-term.
In previous decades, medical technology as well as countless other industries, have shifted the production of components or entire products to locations with lower labour costs, far away from their target market. Unfortunately, there are cases, including the current pandemic, where the vulnerability of these fully optimised supply chains have been laid bare – leading to supply bottlenecks, weakened domestic markets and lessened autonomy.
Additive manufacturing has come to the forefront of the Army’s attention as the service looks for ways to quickly reproduce parts without needing to continuously rely on industry.
In 2019, the service released a new policy directive that outlined its goals to expand its 3D printing processes and established an additive manufacturing center of excellence at Rock Island Arsenal, Illinois.
Maj. Gen. K. Todd Royar, commanding general of Army Aviation and Missile Command, said on the aviation side, he has been using the directive as a baseline for the command’s 3D printing efforts and then incorporating additional standards to ensure that it can meet Federal Aviation Administration regulations as well.
Whether it’s spoilage, delivery timetables, quality control or cyberattacks, successful supply chains can only support patients and customers if they are resilient.
3D printing to the rescue. COVID-19 gave the world a glimpse of how 3D printing can be used temporarily to alleviate the strain on supply chains during demand surges and shortages as it did with medical equipment. Inventors are combining 3D printing with traditional processes creating unique combinations of parts that perform better with lower cost that can be manufactured closer to the customer, all while being more sustainable.
