摘　　要：针对选择性激光烧结快速成形制造的需求,探讨并深入研究了振镜式激光扫描系统的组成,成形过程中线性扫描、图形畸变的校正、扫描系统机械滞后性的补偿、激光功率与扫描速度的匹配及成形精度等关键技术问题。Selective laser sintering (SLS) is one of developing technologies of rapid prototypingmanufacturing. Base on the way of SLS, the paper discusses the influence of the laserparameters about accuracy. At the same time, the paper pays attention to the way of real-izing linear scanning and the correction of distortion image. Additionally, the paper is fo-cused on the influence of mechanical lag characteristic and the relation of scanning speedand the power density of the laser.
