Digital Metal Launches Two Superalloys
To cover the rising demand for 3D- printable superalloys, Sweden-based Digital Metal has launched two super- alloy grades: DM 247 and DM 625. The DM 247 is based on the nonweldable MAR M247, widely used as material for turbine blades and in other applications with elevated temperatures. The DM 625 is an Inconel 625 grade. Its application areas range from seawater applications and chemical processing equipment, to nuclear industry and aerospace.
“We have been receiving qualified requests for these materials from various large companies,” says Ralf Carlström, general manager at Digital Metal. “Many producers within the aerospace and auto- motive business have long been anticipat- ing high-quality superalloys for 3D print- ing. Now we can offer them our binder jetting technology and superalloys, which were developed for our printers.”

Markforged Releases Superalloy for 3D Printing
Markforged, a Watertown, MA-based provider of metal and carbon fiber 3D printers, has announced that Inconel 625 nickel-based super alloy is available with the Markforged Metal X system. Highly resistant to corrosion and high tempera-
Tech Update 3D Cobra, Renishaw Team Up to Optimize
Engine Design
Renishaw, a global
provider of engineering solu-
tions with U.S, operations in
West Dundee, IL, recently
teamed with engine manufac-
turing company Hillsdale, MI-
based Cobra Aero, an engine
manufacturing company to
optimize Cobra’s design
processes for aircraft and
motorcycle engines. Cobra
invested in the Renishaw AM
400 laser powder bed fusion
system to increase its additive manufacturing (AM) capabilities and collaborated with Renishaw to improve the design of a cylinder for an unmanned aerial vehicle (UAV). The result: a single part with complex lattice structures to increase airflow.
“Investing in AM allows us to develop tools and new products for high-value, small- volume applications, speed up the manufacturing process and produce designs that would not be possible using conventional subtractive machining,” says Sean Hilbert, president of Cobra Aero.

tures, harsh-environment applications for the material include aerospace, mining and chemical processing. The Metal X bound powder extrusion process com- bines metal injection molding and fused filament fabrication technologies to cre- ate complex metal parts.

Tier One Racecar Supplier Selects Velo3D to Print Next-Gen
Heat Exchangers
Velo3D, a Campbell, CA-based provider of metal AM solutions, has announced a collaborative partnership with Indianapolis, IN-based PWR, a glob- al provider of cooling solutions for F1, NASCAR and other racing series—as well as the custom-automotive OEM, military and aerospace industries.
The Velo3D and PWR collaboration aims to set a new standard in heat-trans-
fer parts for racing and industrial cooling applications. The two companies will col- laborate on aluminum alloy designs with thinner and more-complex heat exchange features and best-in-class sur- face finishes. PWR will have the first pro- duction Sapphire 3D metal printer in the Asia-Pacific region.
“The Sapphire printer demonstrated the ability to produce class-leading thin- wall capabilities and high-quality sur- faces with zero porosity,” says Matthew Bryson, general manager, engineering, for PWR. “Heat exchanger weight and pressure-drop characteristics have a huge impact on performance and are significant factors in all motorsport cate- gories. Using additive manufacturing to print lightweight structures, and enhanc- ing performance with freedom-of- design, gives us the ability to further optimize these characteristics to the cus- tomer’s requirements while providing the necessary cooling.”
