Small-size stellarator devices with high-temperature-superconducting (HTS) magnetic coils could improve magnetic confinement performance and enable rapid diagnostics of new confinement regimes. In this context, 3D printing with acrylonitrile butadiene styrene (ABS) polymer could be a low cost and rapid manufacturing method that allows the fabrication of relatively complex shapes. However, high precision and geometric complexity are required for stellarator components. Additionally, the combined utilization of HTS magnetic coils and ABS components may require the exposure of ABS components to cryogenic environments. Therefore, this research tested the mechanical performance of additively manufactured ABS at 77 K and correlated its mechanical properties to 3D printing settings. This will allow further mechanical stability analysis about the combined implementation of HTS magnetic coils and additively manufactured ABS components. In this article, Young’s Modulus, Yield Strength and Ultimate Strength at room temperature (RT) and 77 K of additively manufactured ABS are explored while varying layer thickness, raster pattern and infill percentage as 3D printing settings. Conclusions about the influence of each 3D printing setting on each mechanical property are presented.

3D打印设置对室温和77 K下ABS力学性能的影响
具有高温超导(HTS)电磁线圈的小型恒星器设备可以提高磁约束性能,并能够快速诊断新的约束机制。在这种情况下,用丙烯腈丁二烯苯乙烯(ABS)聚合物进行3D打印可能是一种低成本,快速的制造方法,可以制造相对复杂的形状。但是,恒星器组件需要高精度和几何复杂性。另外,HTS电磁线圈和ABS组件的组合利用可能需要将ABS组件暴露于低温环境中。因此,这项研究测试了增材制造的ABS在77 K时的机械性能,并将其机械性能与3D打印设置相关联。这将允许对HTS电磁线圈和增材制造的ABS组件的组合实施进行进一步的机械稳定性分析。本文探讨了室温(RT)的杨氏模量,屈服强度和极限强度以及增材制造的77 K ABS,同时改变了3D打印设置的层厚度,光栅图案和填充百分比。提出了有关每种3D打印设置对每种机械性能的影响的结论。
