摘　　要：激光选区烧结(SLS)是一种增材制造技术,它利用激光逐层烧结粉末并叠加的原理来成形复杂制件,具有材料广泛,无需支撑以及成形精度高等优点。然而,其成形过程中无外力驱动的特点,造成制件中不可避免地存在一定孔隙,使制件性能通常低于传统模塑件。因此,国内外学者提出利用各种纳米填料来增强SLS制件的性能,并取得了良好的效果,已成为本领域研究热点。文中重点介绍了各种用于SLS技术的高分子纳米复合材料,对其研究现状进行综述,并提出今后该领域的发展方向。Selective laser sintering （SLS）, a kind of additive manufacturing technology, uses laser beam to sinter and stack powders layer by layer to build complex 3D parts. It has several advantages including extensive materials, free of support, high precision, etc. However, because of its processing characteristics without external force, there are inevitably some pores inside the parts. This phenomenon makes the properties of the parts made by SLS inferior to those made by traditional processes. Therefore, international and domestic scholars have proposed to use a variety of nanometer materials to enhance the properties of SLS parts and made good progress, thus becoming an international research focus. This paper mainly discussed a variety of polymer based nanocomposites used in SLS, summarized the state of the art and outlooked the developing directions of this field in the future.
