Guide: Recently, the United States3D printingMachine manufacturer3D SystemsThe company has added two new alloys to its material portfolio specifically for the manufacture of high-strength, corrosion-resistant parts on a proprietary direct metal printing platform.3D Systems has certified a durable aluminum alloy material—Scalmalloy, which combines the advantages of traditional casting alloys (such as AlSi10Mg and Ti Gr23) and has an excellent strength-to-weight ratio. On the other hand, the company’s M789 alloy is a cobalt-free alloy with higher hardness and a wider processing window, especially when printing on DMP Flex, Factory 350 and ProX DMP 320 models.
These metals are designed together with APWORKS and BÖHLER Edelstahl, and are certified to be used exclusively for 3D Systems machines, and can now open new ones for their respective userscar,aviationaerospace,MouldManufacturing andenergyField of application.Kevin Baughey, head of 3D Systems’ transportation and racing department, explained: “M789 alloy is used as our metal3D printingPart of the solution can provide our automotive customers with higher accuracy. This allows them to use the technology for applications that require higher fidelity and thinner walls, such as conformal cooling mold inserts and tire tread molds. Our customers in the automotive industry are increasingly relying on additive manufacturing to advance and accelerate their innovation.”

Scalmalloy: ready for takeoff
Scalmalloy of 3D Systems is specifically designed for3D printingIt is designed for load-bearing parts with high weight efficiency, with a tensile strength of 520MPa and a yield strength of 480MPa. Therefore, in internal tests, this material proved to be much stronger than AlSi10Mg, and it is particularly good at producing high-strength, corrosion-resistant parts.When working with APWORKS, 3DSystems also developed a set of ideal parameters for processing this material on the Factory 350 Flex 350 system. The 3DXpert developed by them can be used.software. It is said that when these parameters are used, this alloy can produce robust racing structural components, semiconductor components, and aerospace components such as filters and waveguides.
Dr. Michael Shepard, Vice President of the Aerospace and Defense Department of 3D Systems, said: “Scalmalloy has a very attractive strength-to-weight ratio and is more suitable than many traditional high-strength aluminum alloys.3D printing. These performance attributes make it an ideal choice for aerospace applications, and we are excited to see how our customers will continue to drive their innovation.in ourinvestAdding the ability to add flake alloys to the portfolio to manufacture parts is an important step forward; especially for our aerospace customers. “

3DSystemsCompany certified M789
3D Systems has certified its new’Certified M789′ alloy (also known as BÖHLER M789 AMPO). This optimized material is used to make ultra-high-strength molds and tools. Not only does it contain no cobalt that is harmful to the environment. , And can be further toughened to reach the Rockwell hardness level of 52HRC.Like APWORKS’ Scalmalloy R&D, 3D Systems also collaborated with GF Machining Solutions to certify M789 to achieve highly repeatable part quality and performance results. In the process, the company has developed an extremely corrosion-resistant steel that is ideal for the production of long-term, repetitive tools and parts that require high-temperature stability.
Because of these qualities, the material can therefore be used to make conformal cooling mold inserts, and its durability makes it a potential drill and cutting tool application in the energy sector.Similar to Scalmalloy from 3D Systems, M789 also has important automotive prospects, and its reliability after continuous use means it may be3D printingIdeal for tire molds and transmission systems or axle components.

Scalmalloy’s automotive potential
When 3D Systems launched Scalmalloy, the metal was increasingly being used in automobiles3D printing, And now it has even been approved for Formula One.The Alfa Romeo team lost no time to take advantage of this advantage for its 2021 car3D printingThere are 304 parts, 36% of which are manufactured by Scalmalloy.Just last month, the UK’s Digital Manufacturing Center (DMC) also became Scalmalloy 3D printingThe approved supplier of the component. DMC works with APWORKS and it is said that the parts they producestandardVery high, the organization has been elevated to the top 1% of global Scalmalloy parts suppliers. Elsewhere in the automotive industry,3D printingIt is being used to produce everything from Bugatti brake calipers to Fiat Chrysler suspension parts. With Scalmalloy now certified on 3D Systems’ DMP machines, it is reasonable to believe that this ultra-durable metal will further accelerate this trend and find new applications in the near future.
