Inside GKN Powder Metallurgy’s Acquisition of Forecast 3D

Picture two men sitting at a bar table watching a video on a smartphone. As they enthuse about how much they love it, a bystander might be tempted to think they’re just killing time goofing off. “It’s fantastic technology,” the man with the phone, Forecast 3D founder and CEO Corey Weber, says of the Multi Jet Fusion (MJF) process featured in the time-lapse video that shows a Californian facility in the dead of night illuminated only by the passing of a dozen lights flashing over a dozen powder beds through until the morning. As he pulls back his smartphone, he and Guido Degen, GKN Powder Metallurgy’s President of Additive Manufacturing, look pleased with both the technology and themselves.

GKN Powder Metallurgy’s acquisition of Forecast 3D appears to be natural synergy. Much of Forecast 3D’s expertise exists in polymer 3D printing, serving the aerospace and medical markets on the West Coast. GKN’s focus is metal parts, the bulk of which is for the automotive market in Central Europe and the Midwest of the United States. When GKN highlighted the contrasting technological expertise that exists in both companies, the figureheads at Forecast were on the same wavelength.

“We knew that the opportunity is much bigger than the size of our pockets,” Weber acknowledges. “We needed resources and our goal was to get someone that shared our vision. We found those with GKN. . . . And, honestly, it’s kind of a relief because now we can really focus on polymers and let them handle metals.”

U.S. Army Research Lab Invests to Develop Powerful Metal Powder 3D Printer

The Combat Capabilities Development Command Army Research Laboratory, also known as ARL, recently awarded a 3D engineering and manufacturing company a $15 million contract to create a metal 3D printer that it intends to be the world’s largest, fastest, and most precise.

3D Systems and the National Center for Manufacturing Sciences (NCMS) were awarded funding to create this printer and will partner with ARL and the Advanced Manufacturing, Materials, and Processes (AMMP) Program to advance the leadership and innovation. This printer will impact key supply chains associated with long-range munitions, next-generation combat vehicles, helicopters, and air and missile defense capabilities.

“The Army is increasing readiness by strengthening its relationships and interoperability with business partners, like 3D Systems, who advance warfighter requirements at the best value to the taxpayer,” said Dr. Joseph South, ARL’s program manager for Science of Additive Manufacturing for Next Generation Munitions. “Up until now, powder bed laser 3D printers have been too small, too slow, and too imprecise to produce major ground combat subsystems at scale. Our goal is to tackle this issue head-on with the support of allies and partners who aid the Army in executing security cooperation activities in support of common national interests, and who help enable new capabilities for critical national security supply chains.”

According to the U.S. Army Additive Manufacturing Implementation Plan, the Army has been using additive manufacturing (AM) for two decades to refurbish worn parts and create custom tools. Once developed, the Army will leverage its manufacturing experience by placing the new large-scale systems in its depots and labs. Subsequently, 3D Systems and its partners plan to make the new 3D printer technology available to leading aerospace and defense suppliers for development of futuristic Army platforms.

Industrial-Scale Metal Alloy Powder Plant Launched in U.K.

A U.K.-headquartered company with a solid-state alloy powder technology recently announced its launch of the world’s first industrial-scale metal alloy powder production facility based on the company’s process.

Metalysis will produce valuable alloy powders at the new plant, located in the company’s Materials Manufacturing Centre in Wath upon Dearne, South Yorkshire, U.K.

The Generation 4 (“Gen4”) project was mechanically completed on time in Q4 2017. It has since undergone hot commissioning, trial runs, optimization and handover to Operations, signaling Metalysis’ transition into commercial production following more than a decade of phased technology development.

Dr. Dion Vaughan, Chief Executive Officer, Metalysis

Gen4 is the first facility to take Metalysis’ solid-state, modular, electrochemical process to industrial scale and can produce tens-to-hundreds of tonnes per annum of high value, niche and master alloys. It creates a new U.K. source of supply for global end-users in advanced manufacturing disciplines including aerospace, automotive, batteries, light-weighting, magnets, mining and 3D printing consumables.

A standout benefit of Metalysis’ technology is its multi-metal capability, which enables it to produce alloy “recipes” that comparable processing routes cannot. Where conventional technologies are unable to elegantly combine elements with melting and density differentials, this technology can because it is a solid-state process. Gen4 enables Metalysis to commercially produce a demand-driven product mix of titanium alloys; master alloys including Scandium-Aluminide, which continues to pose excellent launch product potential as announced on 11 June 2018; compositionally complex alloys including High Entropy Alloys; magnet materials; high-temperature materials; and Platinum Group Metal alloys.

“In powering up and operating our industrial plant, Metalysis is poised to achieve its target to generate significant profits from our new South Yorkshire production facility,” said Dr. Dion Vaughan, Chief Executive Officer. “Ours is a true British success story with international implications. Metalysis has grown from the ‘lightbulb moment’ at Cambridge University in the late-1990s, relocated to South Yorkshire to benefit from regional excellence in operational skillsets in the early-2000s, and now onwards towards a bright commercial future.”

Andrea Alborghetti, Technical Manager of TAV Vacuum Furnaces

Heat Treat Today previously posted Parts 1 and 2 of this series on vacuum sintering. Part 1 focused on the two processing steps of debinding and sintering. Part 2 addressed primarily the vacuum sintering furnace itself. This installment analyzes the process and variables involved with binder removal.

Andrea Alborghetti, technical manager of TAV Vacuum Furnaces and contributor to the company’s blog, provides an analysis of burning vs capturing binders, addressing advantages as well as problems that may arise and how to execute control in the process, as in this example:

“One thing that is worth clarifying is that the flames usually seen on the outlet of kilns that use combustible gases (hydrogen, for example) as the process gas, were not originally designed to burn the binder disassociation residues to reduce emissions to the legal limits. Rather, it is solely for disposing of the emitted hydrogen safely, thus avoiding hazardous, potentially explosive atmospheric concentrations being created outside of the kiln.”
