6K additive reduces material cost, recycles metal powder and secures domestic AM metal supply for Incodema3D

6K additive reduces material cost, recycles metal powder, and secures domestic supply of AM metal for Incodema3D.

6K Additive, a division of 6K, a leader in the sustainable production of engineered materials for additive manufacturing and lithium-ion batteries produced from its UniMelt® plasma technology, announces a strategic AM powder supply agreement and a partnership of recycling with Incodema3D, based in Freeville, NY.

Following increased demand and larger order volumes, primarily from aerospace and defense customers, Incodema3D sought to secure a national supply of AM metal powder that met strict quality standards and a solution to recycle their powders and used parts.

6K Additive, through its UniMelt plasma microwave powder production system, is able to provide high volumes of domestically manufactured powder and a way to sustainably recycle scrap metals from Incodema3D through its program powder buyback.

Kevin EngelDirector of Additive Manufacturing and Metrology Operations at Incodema3D explains:

We are now talking to customers about projects for 2023 that will require ten tons of metal powder per month.

“When you use this volume of powder, recycling becomes imperative and sustainability is key to our business. By recycling our waste powder with the 6K additive, we have already been able to reduce our contribution costs for materials by 15%.”

“Add to that the quality standards that Incodema3D and our customers demand, which sets the bar high for any supplier. The 6K Additive has exceeded expectations on this front.

6K Additive’s mission is to provide a solution for global decarbonization in the production of performance additive manufacturing materials that are critical to production in markets such as aerospace, medical and industrial applications.

The company recently released the results of an LCA study conducted by Foresight Management comparing the environmental impact of 6K UniMelt microwave plasma technology to current atomization technologies for producing metal powders.

The results showed a 91% reduction in energy consumption and a 91.5% reduction in carbon emissions when using the 6K UniMelt process. Independent studies can be downloaded here.

Incodema3D has undertaken its own pre-qualification of 6K Additive’s Nickel 625 (Ni625) alloy, a high strength and corrosion resistant alloy popular with many of its customers’ applications.

Internal qualification samples measured tensile strength, microstructure, density and chemical composition and compared the results to existing suppliers and their strategic customer requirements.

6K Additive’s Ni625 exceeded all measurements used in the evaluation, including tensile strength (greater than 125 ksi), yield strength (greater than 85 ksi) and elongation at break (greater than at 30%).

“We tested five samples and each gave density results of 99.9%, which far exceeded the minimum requirement. Anything over 99.5% density in additive manufacturing is a good chunk,” Engel continued.

Securing a scalable national materials supplier was also important to Incodema3D. As the higher cycles of the 6K additive are used and the waste from domestic sources, they are not at risk of supply chain disruptions. For defense customers, a shorter domestic supply chain is also preferable from a security and traceability perspective.

In addition to Ni625, 6K Additive produces a full suite of AM powders including Ni718, low oxygen Ti64 (500-700ppm), 316/17-4 stainless steel, 18150 copper and GRCOP, refractory powders including tungsten, tantalum and rhenium.
