Did you say, “Use wire, not powder for 3D printing?”

 

BY KATHY WEBSTER, CORRESPONDENCE FOR MT360

What is the fastest way to make the hardest parts? Digital Alloys may have the answer with its innovative, patented Joule Printing™ metal 3D-printing process. Previously, printing metal was too slow, too expensive, or too complex for a broad market of applications; Joule Printing™ changes that.  

Rather than expensive powders, the new method uses wire as the raw material and resistance heating for melting and layer bonding. Wire positioning and melting occur simultaneously, lowering time and cost (print speeds exceed 5 kg/hr) while providing repeatability from closed-loop control of melting at the voxel level.  

Digital Alloys is a 3D-printing company that has raised $18 million in funding from venture investors and businesses that hope to benefit from the wire printing technology. According to xconomy.com, the Massachusetts-based start-up is from an area hopping with 3D printing technologies and holds many patents for its method of printing hard metal parts for tools used in automotive and consumer product manufacturing as well as titanium parts used by the aerospace industry.

Digital Alloys will showcase how the Joule Printing™ process works at MT360, a new event connecting manufacturers to the software developers and investors of Silicon Valley. Digital Alloys is one of more than 20 companies partnering with AMT – The Association For Manufacturing Technology* to host the inaugural event. MT360 aims to accelerate the integration of emerging technologies into manufacturing and takes place May 12 – 14, 2020, in Santa Clara, Calif.

In addition to seeing the new metal printing technology in action, Digital Alloys CEO Duncan McCallum will present Metal AM: Joule Printing - The Fastest Way to Make the Hardest Parts. “MT360 visitors will gain an understanding of how Joule Printing works, its advantages over existing additive manufacturing technologies, and the best industries and applications,” says Alex Huckstepp, VP of Business Development, Digital Alloys. “Joule Printing eliminates the need for powder handling, feeding and spreading, binding/debinding, and sintering – and for the costs, safety concerns, time delays and variability these steps introduce.”

At Digital Alloys, “hard” encompasses three areas: producing near-net-shape parts from hard-to-cut metals such as H13 tool steel and titanium; hard-to-make designs such as conformal cooling channels and multi-metal parts; and reducing costs and lead times for hard-to-source parts, such as spares and short run production.


MT360 brings traditional manufacturers, non-traditional tech companies, and venture capitalists into one conference to learn about transformative technologies that will intersect all three worlds.

  • Cognitive Automation – A spectrum of AI or data-related tools that enable automation systems to sense and react to information.

  • Additive Manufacturing – Several related technologies that enable manufacturers to create complex parts and fixtures through 3D printing.

  • Augmented Reality – Technologies that use digital displays to assist with manual tasks.

  • Digital Thread – Electronic connections that allow manufacturing information to follow a product through its entire production process.

In addition to the speakers and panel discussions, MT360 will host a Virtual Factory, which will showcase companies involved in every aspect of these technologies. Attendees can visit and interact with software companies, hardware companies, complete AR-platform providers, and smart manufacturing.
