US-based composite and steel 3D printer supplier Markforged, has launched a pure copper materials choice to be used with the Steel X 3D printer.
By enabling copper 3D printing on the Steel X system, already appropriate with quite a lot of steel supplies, Markforged goals to drive new manufacturing and provide chain efficiencies for purchasers. Based on the corporate, clients now have the potential of lowering lead occasions and half prices, in comparison with conventional manufacturing processes for manufacturing elements with the generally used steel.
“Copper powers our world. It’s in all places. It builds our automobiles, permits telephones, and retains electrical gear working,” feedback Greg Mark, Markforged CEO and Founder. “Copper has historically been an costly and difficult materials to machine and incompatible for 3D printing in a pure kind with different strategies.”
“Now, we’ve made it simpler and cheaper to supply. Markforged 3D printed Copper might be a game-changer for the automotive and electronics industries, and it’ll open the door to innovation throughout many extra.”

3D printing in copper
Copper as a cloth supplies an a variety of benefits to producers in search of to supply elements with the steel. The fabric is well-known for its excessive thermal and electrical conductivity, in addition to its malleability and ductility, making it appropriate for quite a lot of functions; it’s used extensively in circuitry, electrical wiring, and structure.
When processed with additive manufacturing, the same old advantages of the know-how carry over, i.e. extra geometric freedom, much less wastage, decrease price for short-run elements, however processing the fabric has proved difficult to many steel strategies. Current developments have been made nevertheless, for instance, Optomec lately up to date its LENS 3D printing know-how, creating course of parameters for the manufacturing of pure copper elements. The Digital Foundry additionally supplies a copper materials for FDM 3D printing know-how below its flagship line of supplies, referred to as Filamet.
Copper 3D printing has additionally seen functions in house. Researchers from NASA have developed and 3D printed a new copper-based alloy to be used in rocket propulsion elements. 3D printed copper has additionally been used to fabricate the combustion chamber for Launcher’s E-2 rocket engine – reportedly the largest liquid rocket engine combustion chamber 3D printed in a single half.

Markforged’s clients in automotive
Automotive is one trade that can profit from Markforged’s copper 3D printing capabilities, based on the corporate, because the steel is often used inside the sector. “Each automotive manufacturing facility on the planet makes use of copper for welding,” Greg Mark added. “With our 3D printed elements, automotive producers can print the elements they want on demand as an alternative of holding vital stock and can have the ability to design new sorts of welding shanks that had been by no means earlier than potential.”
Markforged states that its 3D printers are deployed at 9 high-valued auto producers around the globe. Partnering with one in all these clients, Markforged was capable of conduct in-depth weld testing utilizing copper, to find out the advantages of 3D printing with the steel. The outcomes confirmed that copper manufacturing on the Steel X lowered the automotive shopper’s half lead occasions by 12x and half prices by 6x, whereas nonetheless retaining the identical resistance as historically manufactured spot welding shanks.
“Advanced manufacturing elements are required to weld tight spots of the automotive physique. They price hundreds of to make and might have months-long lead occasions. However Markforged is altering all of that by enabling producers to supply elements in-house in order that they get them quicker and for considerably decrease prices,” concluded Greg Mark.
