Why AM Certifications are so difficult (Authentise Weekly News-In-Review – Week 97)

For AM to take a greater hold on the industries it’s poised to impact, there are certain angles to smooth out and one of those is certifications. Early adopters of additive production such as aerospace and medical are rightly picky about its certifications and the AM community is making sure to have its own record straight. Safety certifications are the highest priority in this regard and Lockheed Martin’s facility in Sunnyvale, California now holds the first UL certified in the world. Govt. bodies are also moving to help a wider audience to stay within standards, like Health Canada’s newest draft guidance on AM medical devices. However, the main reason why certifications are difficult is that AM is still not an exact science. With fast and multi-spectrum monitoring technologies, we are starting to see what happens during the process. However, certain aspects of the physics behind it are full of variables we don’t understand.

Lockheed Martin extends additive manufacturing to key spacecraft components

Lockheed Martin’s Additive Design and Manufacturing Center in Sunnyvale, California, where the company produces military, commercial and civil space technology, attained a comprehensive safety certification.

“We are the first UL certified additive manufacturing facility in the world,” Servando Cuellar, Lockheed Martin Space Systems engineering senior manager, told SpaceNews.

High-Speed Cameras Used to Monitor 3D Printing Process

3D printing, particularly laser-powder bed fusion or L-PBF, requires a great deal of monitoring to avoid defects and flaws in the final parts. In a thesis entitled “Process Monitoring for Temporal-Spatial Modeling of Laser Powder Bed Fusion,” a student named Animek Shaurya studies the use of high-speed video cameras for in-situ monitoring of the 3D printing process of nickel alloy 625 to detect meltpool, splatter, and over melting regions to improve the quality of the print.

The Confluence of AI and AM (Authentise Weekly News-In-Review – Week 92)

We’ve witnessed how the digital age is transforming the manufacturing industry and nowhere it is more apparent than in the contributions that AI is giving to the field. Advanced computing capabilities are being coupled with full-spectrum sensors and autonomous “thinking”. These systems are being developed in AM for a variety of benefits. First, they can help with in-process fault detection, constantly monitoring the printer for defects where the human eye can’t see and even adjust it to fix the problem on the spot. Bringing a trustworthy AI system in the fray opens up possibilities for decentralized manufacturing, where human skill isn’t needed to produce good quality, reliable parts. Such manufacturing units can be located anywhere, operate autonomously and even cooperate with one another to reach a certain goal. Authentise is presently using AI technologies to drive process estimates, providing an accurate, reliable window into your operations.

 

US Navy and Lockheed Martin Are Building AI-Driven 3D Printing Robots

Lockheed Martin

A new generation of smart 3D printers is under development which will use artificial intelligence to oversee and optimize 3D printed parts. The US Navy’s Office of Naval Research (ONR), which is funding the ambitious project, has recently announced a two-year $5.8 million contract. There are four partners working on this project, led by Lockheed Martin’s Advanced Technology Centre. The collective aim is to be able to create robots that can make independent decisions on how to optimize the production of complicated 3D printed parts.

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.

Space, the final frontier will need 3D printing to make it happen (Authentise Weekly News-In-Review – Week 83)

The space industry finds itself in the sweet spot of many advanced technologies, hoping to improve mission success by looking at its problems from all sides. 3D printing has already proved to be a powerful tool for these purposes, with its fast iterative cycles and outside-the-box manufacturing paradigm. What Airbus has been doing for its airplanes, Lockheed Martin is pushing beyond with 3D printed parts that can reach sizes just under 4ft, halving production time, costs and reducing weight. Still, it will be extremely expensive to launch humans to Mars or even the Moon in the near future. For that, we’ll have to rely on robots (with much lower maintenance requirements). By sending autonomous robots to another planet, they can be tasked to 3D print sustainable habitats for us in-situ, by sourcing local materials. Empowered by the digital thread, the designs for these habs can be experimented upon and reiterated, and contests are being created periodically to further improve those that, in a not too distant tomorrow, we could call homes.

 

Lockheed Martin 3D printed an impressive titanium dome for satellite fuel tanks

Lockheed Martin has just taken 3D printing to new heights, printing an enormous titanium dome meant for satellite fuel tanks. It’s the largest space part the company has 3D printed to date and measures 46inch  in diameter — just under 4ft.

“Our largest 3D printed parts to date show we’re committed to a future where we produce satellites twice as fast and at half the cost,” said Rick Ambrose, Lockheed Martin Space executive vice president. “And we’re pushing forward for even better results. For example, we shaved off 87% of the schedule to build the domes, reducing the total delivery timeline from two years to three months.”

Here’s What We Know About The Robots That Might Build Our First Homes on the Moon

Rovers may soon traverse the surface of the Moon yet again. This time, though, they’ll have one noble mission: to build shelter the first human colonizers will inhabit. A team of Japanese scientists is working to make this a reality. They started a company called ispace with the intention of launching a private space mission to the Moon. ispace envisions an entire colony, called “Moon Valley”, constructed not by human astronauts, but by robots instead. And they want to get started on it soon: the team is planning its first mission for late 2019, and a second in 2020.

Lockheed Martin Looks to Catch Up in 3D Printing

Lockheed Martin is making titanium propellant tanks for satellites using a Chicago company’s electron beam additive manufacturing technology.

Robert Ghobrial, additive manufacturing lead for the company’s training and simulation location in Orlando, FL, spoke at SME’s “Additive Manufacturing Applications: Innovations for Growth” seminar in October, at advanced energy technology accelerator NextEnergy, in Detroit. He traced his work with 3D printing back to 2012, when his team received some MakerBot printers that largely went unused. Along the way, Ghobrial coined the phrase, “The 5Ps of Additive Manufacturing™,” a manufacturing model that describes how AM can help aerospace, defense and other businesses.
