固态金属3D打印专家Fabrisonic已经使用了紧凑型Soniclayer 12003D printer to create better value satellite heat exchangers forNASA’s Jet Propulsion Lab（JPL）。
Instead of using its standard SonicLayer 7200 to produce the thermal regulators and their complex internal geometries, Fabrisonic opted to deploy its smaller, more efficient machine. The resulting components proved not only to be more cost-effective, but their seals have passed the JPL’s stringent testing, including a simulatedAtlas V rocket launch。
Fabrisonic’s ongoing NASA partnership
Fabrisonic成立于2011年,是一个金属3 d打印service provider that fulfills orders using its proprietary超声添加剂制造（UAM）过程。混合制造技术实质上涉及超声焊接的金属磁带到层中，一旦对象成形，使用CNC加工就可以更复杂。
Given that the technology operates at low temperatures, it’s sometimes utilized to3D print integrated electronics, and the company recently experimented withfabricating larger hybrid structures。但是，更常见的是，该过程已在航空航天应用中部署，而Fabrisonic已多次与NASA合作。
Working withLuna创新, for instance, the company managed to3D打印传感器直接在NASA燃油管上, while in a separate SBIR project, it’s currently developingUAM耐腐蚀的覆层。Now, as part of its most recent NASA collaboration, Fabrisonic has leveraged its UAM process to create yet another end-use spacefaring component.
创建调节热量设备
在其最新的NASA项目中，Fabrisonic通过犹他州立大学的(USU)College of Engineeringto develop two unique parts for a thermal satellite system. Although fully-hermetic components have以前已经实现使用Fabrisonic的Soniclayer 7200 3D打印机，该公司的工程师选择使用1200机器，而其成本效益更高的10 x 10 x 10英寸10英寸构建量改为使用。
在生产过程中，团队采用了组合的添加剂和减法方法，使用CNC加工来创建零件的复杂流体通道，并用支持材料填充它们。一旦到位，这些支撑物有效地阻止了任何多余的金属在印刷时被挤出到设备的空腔中。
After post-processing, in which the support material was washed out, the parts were machined into their final shape, leaving exchangers with smooth, accurate fluidic passages. To test that the devices were hermetically-sealed and leak-proof (something that’s essential to its end-use application), they were then subjected to rigorous JPL testing.
最终，这些零件征服了一系列测试，包括被淹没在水下，承受50 psi的压力和对船上经历的振动的模拟。通过初步评估，这些设备现在正在前往USU进行最终测试。，将使用氦泄漏检测器来模拟空间真空。
3D打印热交换器的上升
3D printing has been used to produce many different heat exchangers over the years, with applications ranging from automotive to clean energy generation.
In October 2017, French chemical firmAir Liquidewon an award from the欧洲化学工程联合会(EFCE) for its3D printed heat exchanger。By steam reforming natural gas, the additive manufactured reactor was reportedly able to increase the efficiency of its hydrogen production process.
Similarly,GE研究, the R&D wing of American conglomerateGE，已经使用3D打印来产生超低发射热交换器用于发电应用。高级添加剂设备是为期两年项目的一部分而创建的，旨在使电厂更加清洁，更高效。
Other 3D printing industry enterprises including法苏恩还尝试了优化热调节设备和中国公司3D打印了铜概念证明in 2019. By fabricating the complex spiral-shaped device as a single part, Farsoon was able to reduce its total cost by around 35%.
