Australian Soldiers to Print Metal Parts, Build a Resilient Supply Chain
The Australian Army announced a $1.5-million investment to a 12-month pilot of metal cold-spray technology from Spee3D.  The program includes training soldiers in 3D printing on machines installed on-base and deployed in the field for multiple Army exercises.

Spee3D, which partnered with the Advanced Manufacturing Alliance (AMA) and Charles Darwin University (CDU) to deliver the program, collaborated with CDU to form AMA in 2017. AMA will train soldiers in all the skills needed to design and print parts, from CAD software to printer operation, part post-processing, testing and certification.

Stainless Steel Printed on Budget Desktop Setups
The additive manufacturing program at Somerset (KY) Community College (SCC) has successfully 3D printed Type 316L stainless steel metal parts on several low-cost desktop printers, and then successfully welded the parts together using the gas-tungsten-arc process.  SCC employs a version of the extrusion-based bound metal additive manufacturing process, by customizing low-cost FDM printers and upgrading them for printing using metal-infused filaments (provided by Virtual Foundry and BASF).

2020 AMUG Conference—Join Us
The AMUG Conference brings a unique experience to additive manufacturing (AM). Designed to facilitate information exchange between AM users, the conference brings together individuals of all experience levels that wish to do more with the technology. What makes the AMUG Conference different is the openness of attendees and willingness to share. March 22 – 26, 2020.




OK Oil-and-Gas Supplier Taps Metal AM for Downhole Tools
Duncan Machine Products (DMP) has entered the world of metal additive manufacturing (AM) as the Duncan, OK, supplier to the oil-and-gas industry has purchased a Velo3D Inc. Sapphire printer and accompanying Flow preprint software and Assure quality-management software. Primarily involved in precision machining, DMP acquired the printer in response to increasing demand from customers for improved part performance and shorter lead times, and will take delivery in the second quarter of this year.

DMP has received orders to 3D print a minimum of 1500 parts for downhole tools used in onshore and offshore exploration. This order easily could increase by 10 times in the next 24 mo., according to Chris Billings, DMP co-owner.

“The conditions under which downhole tools must perform are hostile and include extreme-pressure and high-temperature situations, requiring a robust and dependable manufacturing solution,” Billings says, noting that the company will employ metal AM to replace investment casting as the manufacturing process for these tools. “We know that AM is essential for our future expansion. We chose Velo3D because its Sapphire printer can handle the most geometric complexity, and its support-less process doesn’t require customers to redesign their parts. This will enable us to bid on a larger portfolio of projects.”
