U.S. 3D printer manufacturer3D Systemshas added two new alloys to its material portfolio that are specifically designed to yield high-strength, corrosion-resistant parts when used with its proprietaryDirect Metal Printingplatform.
该公司凭借其“经过认证的ScalMalloy”，获得了耐用的铝制资格，该铝在传统铸造合金（如Alsi10mg和Ti Gr23）之间“弥合了差距”，并且具有出色的强度与权重比。另一方面，该公司的“认证M789”是一种无钴合金，具有高度硬度和宽的处理窗口，尤其是在印刷上DMP Flex，，，，工厂350andProX DMP 320。
与旁边设计APWORKSandBÖHLER Edelstahl并专门用于与3D系统机器一起使用的金属，现在可以向各自的用户开放新的汽车，航空航天，模具制造和能源部门应用。
“有M789作为我们的金属3 d打印溶解tion delivers greater accuracy to our automotive customers,” explains Kevin Baughey, Leader of 3D Systems’ Transportation & Motorsports Segment. “This enables them to use the technology for applications that require higher fidelity and thinner walls, like die inserts with conformal cooling and tire tread molds.”
“Our customers in the automotive industry are increasingly relying on additive manufacturing to advance and accelerate their innovation.”
Scalmalloy: primed for take-off
3D Systems的ScalMalloy专为3D打印重量的承重组件而设计，其拉伸强度为520MPA，屈服强度为480MPa。结果，在内部测试期间，该材料证明自己比Alsi10mg强得多，尤其擅长生产高强度的耐腐蚀部分。
与APWorks合作，3D Systems还开发了一个理想的参数集，用于处理其工厂350 Flex 350系统上的材料，可以使用其应用程序应用3DXpert software。According to the firm, when used with these parameters, the alloy enables the production of robust structural motorsport components, semiconductor parts and aerospace components like filters and waveguides.
3D Systems'S Systems's Aerostospace＆Defense tement的副总裁Michael Shepard博士说：“ Scalmalloy具有非常吸引人的强度与重量比，并且比许多传统的高强度铝合金更适合3D打印。”“这些性能属性使其非常适合航空航天应用，我们很高兴看到客户将如何继续通过其创新推动信封。”
“Adding the capability to additively manufacture parts from Scalmalloy to our portfolio is an important step forward; especially for our aerospace customers.”
3D Systems’ ‘Certified M789’
With its new ‘Certified M789’ alloy (also known asBöhlerM789Ampo), 3D Systems has qualified a material that’s optimized for creating ultra-high-strength molds and tooling. Not only is the metal free from environmentally-damaging cobalt, but it can be further toughened, allowing it to reach a Rockwell Hardness Rating of 52 HRC.
Much like its Scalmalloy R&D with APWORKS, 3D Systems has also worked withGF加工解决方案认证M789获得高度重复的零件质量和财产结果。在此过程中，该公司开发了一种极为耐腐蚀的钢，非常适合使用长期重复应用的工具以及在高温下需要稳定性的组件。
Due to these qualities, the material can therefore be used for creating mold inserts with conformal cooling, while its durability lends it potential drill and cutting tool applications in the energy sector. Similarly to 3D Systems’ Scalmalloy, M789 also holds significant automotive promise, and its reliability after continued use, means that it could be ideal for 3D printing tire molds and drivetrain or axle parts.
For those interested in finding out more about 3D Systems’ materials, both Scalmalloy and M789 are set to be exhibited atRAPID+TCT从9月13日至15日，2021年。在其展位（E7601），该公司提供“探索这些材料的优势”，并帮助客户实现通过其处理的最佳设置Application Innovation Group。
Scalmalloy’s automotive potential
3D Systems’ Scalmalloy launch comes at a time when the metal is increasingly finding automotive 3D printing applications, and it has now even beenapproved for use within Formula 1。不浪费时间来利用这一点，Alfa Romeo Racing团队有3D printed 304 partsfor its 2021 car, 36% of which have been manufactured from Scalmalloy.
就在上个月，英国的Digital Manufacturing Centre(DMC) also became anapproved supplier of Scalmalloy3D printed parts. Working alongside APWORKS as well, the DMC is said to be producing parts of such a high standard, that they’ve lifted the organization into the top 1% of Scalmalloy part suppliers worldwide.
在汽车行业的其他地方，3D打印被用于生产所有内容布加迪制动卡钳到Fiat Chrysler suspension parts。由于Scalmalloy现在有资格在3D Systems的DMP机器上，因此有理由认为超耐金属将进一步加速这一趋势，并在不久的将来找到新的应用。
