6K Additive, a division of 6K, a pacesetter within the sustainable manufacturing of engineered supplies for additive manufacturing and lithium-ion batteries produced from its UniMelt plasma know-how, has entered right into a strategic AM powder provide settlement, and recycling partnership, with NY-based Incodema3D, a manufacturing provider in steel additive manufacturing.
Following elevated demand and bigger quantity orders, predominantly from aerospace and protection clients, Incodema3D sought to safe a home AM metals powder provide that met strict high quality requirements and supplied an answer for recycling their used powder and elements. 6K Additive, by way of its UniMelt plasma microwave powder manufacturing system, is ready to present excessive volumes of domestically manufactured powder and a path to sustainably recycle Incodema3D’s used metals by way of its Powder Purchase Again program.
“We’re speaking to purchasers now about tasks for 2023 that can require ten tons of steel powder monthly. Whenever you’re going by way of that quantity of powder, recycling turns into crucial, and sustainability is vital to our enterprise. By recycling our used powder with 6K Additive we’ve got been capable of drive down our contribution prices for materials by 15% already. Add to it the standard requirements each Incodema3D and our clients demand units a excessive bar for anyone provider. 6K Additive overachieved on this entrance,” defined Kevin Engel, director of additive manufacturing and metrology operations at Incodema3D.
6K Additive’s mission is to supply an answer for international decarbonization in producing efficiency additive manufacturing supplies which can be vital to manufacturing in markets akin to aerospace, medical, and industrial functions. The corporate lately launched outcomes from an LCA examine carried out by Foresight Administration evaluating the environmental affect of 6K’s UniMelt microwave plasma know-how to present atomization applied sciences to supply steel powders. The outcomes confirmed a 91% discount in vitality use and a 91.5% discount in carbon emissions when utilizing the 6K UniMelt course of.
Incodema3D undertook its personal pre-qualification of 6K Additive’s nickel alloy 625 (Ni625), a high-strength and corrosion-resistant alloy, in style with lots of its buyer’s functions. Inner qualification samples measured tensile energy, microstructure, density, and chemical composition and benchmarked the outcomes in opposition to current suppliers and their strategic buyer’s necessities.
6K Additive’s Ni625 surpassed each measure used within the evaluation, together with tensile energy (better than 125 ksi), yield energy (better than 85 ksi), and elongation at break (better than 30%). “We examined 5 samples and each returned density outcomes of 99.9%, which far exceeds the minimal requirement. Something over 99.5% density in additive manufacturing is an efficient half,” stated Kevin Engel.
Securing a scalable home supplies provider was additionally vital to Incodema3D. As 6K Additive upcycles used and waste materials from home sources, they don’t seem to be at as a lot of a threat of provide chain disruptions. For protection clients, a shorter home provide chain can be preferable from a safety and traceability standpoint.
Along with Ni625, 6K Additive produces a full suite of AM powders together with Ni718, low oxygen (500-700ppm) Ti64, chrome steel 316/17-4, copper 18150 and GRCOP, refractory powders together with tungsten, tantalum, and rhenium.
