摘　　要：目的为了顺应全球范围的高效、节能、低碳、环保的可持续发展要求,满足消费者对于高端、可定制个性化包装产品的需求,研究开发一种高价值可持续型木质基材料-红木/聚醚砜复合材料作为包装材料。方法采用激光烧结3D打印技术作为具有复杂结构的可定制个性化包装产品制造的先进成型技术,结合力学性能测试和微观结构表征技术研究制件性能,以及加工参数对性能的影响。结果红木/聚醚砜混合材料粉末组分分布均匀,具有良好的铺粉流动性,激光烧结制件具有天然红木的外观和芳香,木纤维与聚醚砜界面间以机械互锁形式粘接,制件具有较好的力学性能及成型精度。制件的拉伸强度及弯曲强度在激光功率为9 W时达到最大,分别为4.88,7.87 MPa。结论红木/聚醚砜复合材料用于激光烧结技术,具有很好的可加工性能,实现了珍贵材料加工剩余物的高附加值利用。采用3D打印技术可以实现高端定制复杂结构包装产品的设计制作。The work aims to research and develop a high valued sustainable rosewood/PES composite as packaging material, for the purpose of adapting to the global sustainable developing trends of high efficiency, energy saving, low carbon emission and environmental compatibility, and complying with the requirement of high-end individual custom carton. Laser sintering of 3 D printing technology was selected as the advanced prototyping technology to produce individual custom packaging product with complex structure. Combined with mechanical testing and microstructure characterization, the sintered part＇s properties and the effect of processing parameters on the properties were studied. Rosewood/PES composite powder compositions had an even distribution, and good flowability during spreading. The sintered part possessed natural rosewood appearance and aroma. The interface between wood fiber and PES was formed through mechanical interlock. The sintered part had good mechanical strength and forming accuracy. The tensile strength and bending strength of sintered parts reached the peak of 4.88 and 7.87 MPa at a laser power of 9 W, respectively. Rosewood/PES composite has been shown to be extremely processable when applied in laser sintering and it realizes the high added-value utilization of the remainder of precious material processing. 3D printing can enable the design and prototyping of high-end custom packaging product with complex structure.
