The use of thermoplastic elastomers with conductive fillers enables one to produce strain sensors in a variety of shapes and forms using thermoplastic processing routes. However, some methods of thermoplastic processing are costly and require long production times. Filament printing, an additive manufacturing route that still exhibits a high annual growth rate, is a cost- and time-efficient method of additive processing. In this study a commercial conductive thermoplastic polyurethane (TPU) based fused deposition modelling (FDM) filament and a styrenic block copolymer (TPS) compound were extruded through two different FDM-based nozzle sizes, using an FDM 3D printer. The TPU material could only be extruded through a 0.5 mm orifice; using a lower nozzle diameter resulted in a non-elastic brittle filament. For the TPS material it was possible to produce filaments with diameters of 0.3 mm and 0.5 mm. In all dynamic tests, the extruded commercial piezoresistive TPU filament either sh...

用熔融沉积建模3D打印机挤出的用于应变传感的热塑性弹性体复合长丝

热塑性弹性体与导电填料的结合使用,使人们能够使用热塑性加工路线生产各种形状和形式的应变传感器。但是,某些热塑性加工方法价格昂贵并且需要较长的生产时间。长丝印刷是增材制造的一种途径,至今仍以较高的年增长率增长,是一种经济高效的增材加工方法。在这项研究中,使用FDM 3D打印机通过两种不同的基于FDM的喷嘴尺寸挤出了基于商业导电热塑性聚氨酯(TPU)的熔融沉积建模(FDM)细丝和苯乙烯嵌段共聚物(TPS)化合物。TPU材料只能通过0.5毫米的孔口挤出。使用较小的喷嘴直径会导致产生非弹性的脆性长丝。对于TPS材料,可以生产直径为0.3毫米和0.5毫米的细丝。在所有动态测试中,挤出的商用压阻TPU灯丝都可以...
