EOS has launched a brand new EOS M 290 1kW metallic powder mattress fusion (PBF) system, designed particularly with copper in thoughts. Initially developed by its customized machine constructing subsidiary, AMCM, the system is now obtainable as a sequence mannequin. The 3D printer measures 250x250x250 mm, has a 1kW laser, and may construct at a charge of 27.8 mm³/h. The corporate is initially providing two certified supplies: CuCp, 99.95% pure copper for purposes requiring electrical or warmth conductivity, corresponding to warmth sinks, antennas, and wave guides; and EOS Copper CuCrZr, optimized for mechanical properties and warmth remedy along with its conductive properties. This mix of chromium, copper, and zirconium is used for electrical connectors, warmth exchangers, rocket combustion chambers, induction coils, and drive elements.
With this new printer, EOS is catering to a booming market within the New Area and protection sectors for copper merchandise. The corporate identifies vitality, transport, and house as vital markets, with warmth sinks and drives, warmth administration, and inductors highlighted as key elements. Moreover, extra industrial elements are being manufactured in copper with additive manufacturing. In situations the place brazing is required, corresponding to in heating parts or induction coils, the excessive error charges in brazing could make 3D printing a viable various—as detailed in Additive Manufacturing Analysis’s “Copper Additive Manufacturing 2020–Market Database and Outlook” report on the subject. Optimized electrical drives can be produced via 3D printing of copper. This might be helpful for AM Ventures’ portfolio firm Additive Drives.
EOS is a bit late to the copper celebration, as Trumpf, for instance, already presents the TruPrint 500 for copper, which makes use of a inexperienced laser working on the 515 nm wavelength. Moreover, different copper supplies can be found on numerous platforms. Nevertheless, the transition from AMCM to EOS is a superb method. Irrespective of how unconventional the required machine, AMCM can create it. This technique supplies bleeding-edge customers in house and different sectors with a straightforward choice to get a customized printer suited to their particular materials or utility. AMCM, being extra client-focused and versatile than the bigger EOS, can meet and cater to shoppers’ wants extra swiftly.
That is, in and of itself, an excellent potential marketplace for 3D printing. The additive manufacturing business is transitioning from lab to fab, with extra entities participating in end-part manufacturing. Whereas a great prototyping machine would wish to accommodate many supplies and kinds of elements, in manufacturing, there’s usually a desire for an optimized machine software designed to work with a single materials. It’s widespread to print the identical form or the identical household of shapes repeatedly. A machine tailor-made for one household of elements might be optimized for its goal and the half household, making it considerably totally different from the extra prototyping-oriented machines which can be extra commonplace right this moment. Due to this fact, the method of providing customized machines via AMCM after which serializing those who meet the wants of rising prospects is great. Extra firms ought to provide the identical service. Some key purposes, corresponding to antennas or warmth sinks, are more likely to devour a disproportionate quantity of machines within the coming years, highlighting this method as a key differentiator for EOS.
“Our award-winning EOS M 290 is likely one of the most generally used metallic AM machines on this planet, and now the household is rising. Curiously, the EOS M 290 1kW was developed by EOS’ AMCM group as a part of its customized AM portfolio. The decision to additional commercialize this platform was exceptionally sturdy on account of market demand, so now we’re slip-streaming it into EOS’ broader portfolio,” stated Monica Smith, EOS metallic product line supervisor.
One firm EOS references is inductor producer GBZ Mannheim GmbH & Co.KG. Thomas Corell, Managing Director at GBZ Mannheim, acknowledged:
“Additive manufacturing and the brand new one-kilowatt know-how enable us to design and manufacture copper inductor purposes which can be extra succesful, sturdy and now produced in a single piece with no soldering factors. The core parts of inductor purposes are actually built-in in a single construct, and the outcomes are a lot increased optimization of the cooling channels, decrease energy consumption in the course of the product lifecycle, and we’re seeing nice reproducibility on the production-side of issues.”
In comparison with brazing or different manufacturing strategies, 3D printing can provide cost-effective manufacturing for elements corresponding to inductors, antennas, warmth exchangers, and drive elements. Much less soldering equates to much less guide labor, in addition to a decreased probability of constructing costly errors and producing much less scrap. Additional, design optimization might result in increased efficiency than standard strategies. The thrill about inductors is well-founded, as antenna, warmth exchangers, and drive elements might additionally develop into vital purposes. The M290 1 kW might turn into some of the necessary machines of all.
