摘要/Abstract

摘要：

提出利用正弦波振动改善熔丝成型挤出材料丝间的结合颈的新熔丝成型方法，即采用压电陶瓷对熔丝成型热熔喷头施加纵向（沿着熔体流动方向）正弦振动场以增大结合颈尺寸，实现制品成型质量的提升。完成熔丝成型设备的振动改装，基于改装后的设备制备实验样件，并在电子显微镜下对样件结合颈的尺寸进行了测量；建立了结合颈尺寸的理论计算模型，并与实测结果进行了比较。结果表明，辅以振动的新熔丝成型可有效增大结合颈，且结合颈随着振动频率或幅值的增大而进一步增大，横、纵向结合颈最大增幅分别为21.4%和22.3%；结合颈尺寸的理论计算与测量结果比较误差为2%~12%，正确、可靠，能够准确地预测结合颈。

Abstract:

The bonding neck between the extruded material filament is a key factor affecting the forming quality of fused filament fabrication products. Therefore， the novel method of using sinusoidal vibration to improve it is proposed， that is， using piezoelectric ceramic to apply longitudinal （along the melt flow direction） sinusoidal vibration to the extrusion liquefier to increase the bonding neck， and thereby to improve the built products′ forming quality. The vibration modification on the fused filament fabrication equipment was completed， based on which the testing samples were prepared. Each sample′s bonding neck was measured with electron microscope. The corresponding theoretical model was established， and the predictions were compared with the measurements. The test results show that using vibration can effectively increase the bonding neck， which further increases with the increasing vibration frequency or amplitude. The growth of the horizontal and longitudinal bonding neck is up to 21.4% and 22.3%， respectively. The difference between the predicted and measured results is 2%~12%， indicating that the proposed model is correct and reliable， and it can predict the bonding neck accurately.
