Abstract

The present fused deposition modeling (FDM) printing process has concentrated on combining metal or ceramic filled with polymer because it could provide a strong composite in layered manufacturing technology in comparison to a single polymer material. However, the ability of the composite material to flow into the extruder becomes an obstacle because of the changes in the polymer concentration and dispersion of filler particles in producing the printed part. Hence, the rheological behavior of Hydroxyapatites (HAp) / Polylactic Acid (PLA) composite with different contents of HAp was studied to assess its ability to flow through the extruder during the 3D printing process. Measurements such as pycnometer density, thermal analysis (DSC) and FT-IR were performed on the composite feedstock containing a variation of 10% to 30% HAp powder. The feedstocks behavior then were characterized by rheological tests at three different temperatures (140 oC, 150 oC, and 160 oC). The composition of PLA/20HAp has produced optimum rheological behavior with effective flow behavior index (n) and activation energy (E) of 0.396 and 89.03 kJ/mol, respectively which is suitable for extruding out the HAp/PLA composite to become a 3D printing filament material.

用于 3D 打印丝的羟基磷灰石/聚乳酸复合材料流变行为初步研究

目前的熔融沉积建模（FDM）打印工艺主要是将金属或陶瓷填充到聚合物中，因为与单一聚合物材料相比，这种材料可以在分层制造技术中提供一种坚固的复合材料。然而，在生产打印部件时，由于聚合物浓度和填料颗粒分散性的变化，复合材料在挤出机中的流动能力成为一个障碍。因此，我们研究了不同HAp含量的羟基磷灰石（HAp）/聚乳酸（PLA）复合材料的流变行为，以评估其在三维打印过程中流经挤出机的能力。对含有 10%-30%HAp粉末的复合原料进行了密度计密度、热分析（DSC）和傅立叶变换红外光谱等测量。然后在三种不同温度（140 摄氏度、150 摄氏度和 160 摄氏度）下进行流变测试，对原料的行为进行表征。聚乳酸/20HAp 成分产生了最佳流变行为，其有效流动行为指数（n）和活化能（E）分别为 0.396 和 89.03 kJ/mol，适合将 HAp/PLA 复合材料挤出成为 3D 打印丝材料。
