来自八个欧洲国家的21个工业和研究伙伴将聚集在一起MULTI-FUN project- 一项为期三年的计划，旨在推进多物质金属添加剂制造。雷电竞充值
该项目由EU’s Horizon 2020innovation program and comprises two parts: the first will involve improving the performance and efficiency of 2020’s metal AM systems while the second will be focused on enabling the multi-material fabrication of complex 3D models without sacrificing large part size capabilities.
An ambitious project
工作,在其核心,将看到的完成four science and technology objectives related to multi-functional and multi-material 3D printing. This is not specific to any one AM technology, as the project aims to advance the sector as a whole. Some of the partners will be working on the PBF process while some may be working on WAAM. A few of the partners will even be working on developing novel materials specifically for multi-material printing.
By the end of it, the consortium hopes its work will enable the printing of a number of previously impossible objects including multi-material heat sinks with high thermal conductivity and complex metal parts with embedded electronics. The partners also hope to be able to integrate and print tailored optical fibers for structural health monitoring purposes.
The four objectives
The first objective entails the development of five new materials specifically for AM, three of which will use nanotechnology. These materials will feature a number of impressive thermal, electrical, and wear resistance properties to enable the creation of new multi-functional products.
第二个目标旨在开发一个具有硬件和软件的全新系统，以将几种AM技术集成到一个系统中。这样，可以使用不同的制造技术打印五种新材料。总的来说，合作伙伴希望最终获得至少十种新的多物质组合，并用不同的金属AM技术打印。
第三个目标将看到新开发的多物质印刷系统的七个物理演示者的印刷和评估。这些示威者将用于三种用例（结构零件，模具和测试设备），并将覆盖四个市场（汽车，航空，航空航天和制造）。
第四个也是最后一个目标是回头迭代材料，硬件和演示器设计，以评估和改善项目的环境和经济影响。结果，合作伙伴希望在适应新技术的过程中制定一套新标准，用于多物质金属3D打印和支持监管机构。
Multi-material 3D printing has been attempted before, but it’s still very much in its infancy. Earlier this year,Belgium-basedAerosintdeveloped a special双加recoaterand deployed it in a laser PBF3D printer made byAconity3D. The recoater utilizes two rotating patterning drums that each selectively deposit a separate powder onto the powder bed.
Elsewhere,Harvard University researchers developed a new method of multi-material 3D printingcalled MM3D. The novel technique utilizes a printhead with eight different material channels and only one nozzle. The material being deposited can be switched up to 50 times a second, enabling faster print times with crisp material interfaces in a single part.
