In this paper, additive manufacturing was used in order to produce hose prototypes for peristaltic linear pneumatic actuators. In order to optimise the endurance of the actuator, we 3D printed different thermoplastic polyurethane elastomers with different shore hardness levels using ARBURG Plastic Freeforming technology. Furthermore, effects of the hose geometries on the lifetime of the actuator were investigated. Experimental evidence showed that the lifetime of the actuator was dependent on the combination of the hose design and on the material used to manufacture the hose. Moreover, experimental tests showed that the use of the Aurburg-Freeformer 3D printing technology led to a much higher hose endurance than the one reported by using the fused layer manufacturing technique.
在本文中，采用增材制造来生产用于蠕动式线性气动执行器的软管原型。为了优化执行器的耐久性，我们使用阿博格塑料自由成型技术3D打印了具有不同邵氏硬度水平的不同热塑性聚氨酯弹性体。此外，还研究了软管几何形状对执行器寿命的影响。实验证据表明，执行器的寿命取决于软管设计与制造软管所用材料的组合。此外，实验测试表明，使用阿博格自由成型3D打印技术所得到的软管耐久性比使用熔融层制造技术所报告的耐久性要高得多。
