Data for: Viscous sintering kinetics of biopolymer filaments extruded for 3D printing (Dynamic Mechanical Analysis)

Results of Dynamic Mechanical Analysis -DMA- performed on extruded filament based on zein plasticized by 20w% glycerol (diameter_filament = 2 mm; lenght_filament=20mm). The mechanical active length between the two grips is 10 mm. The extrudate is characterized in tensile mode at 1Hz, with strain set at 0.1% and heating rate at 3°C/min. Values are presented for the storage modulus (E', [Pa]), the loss modulus (E'', [Pa]) and the damping factor (tan_delta=E''/E', [-]).以20w%甘油增塑的玉米醇溶蛋白挤出长丝的动态力学分析（Dynamic Mechanical Analysis，DMA）测试结果：该长丝直径为2 mm，长度为20 mm。 两个夹具间的有效力学作用长度为10 mm。本次测试采用拉伸模式对该挤出长丝进行表征，测试频率为1Hz，应变量设置为0.1%，升温速率为3℃/分钟。 本次测试给出了储能模量（storage modulus，E', [Pa]）、损耗模量（loss modulus，E'', [Pa]）以及损耗因子（tanδ=E''/E'，[-]）的相关测试数值。
