【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。
[Abstract]:Laser selective sintering (SLS) is a kind of material augmentation technology, which uses the principle of laser sintering powder and superposition to form complex parts. It has the advantages of extensive materials, no support and high precision. Due to the fact that there is no external force driving in the forming process, there are some pores in the parts, and the properties of the parts are usually lower than those of the traditional molded parts. Therefore, many scholars at home and abroad have proposed to use various nano-fillers to enhance the properties of SLS parts. In this paper, various kinds of polymer nanocomposites used in SLS technology are introduced, their research status is summarized, and the development direction of this field in the future is put forward.
