摘　　要：介绍了激光快速成形技术的基本原理和方法，通过血泵模型机的设计和制备，研究了利用该项技术制造复杂的螺旋叶片零件的基本方法和技术，并对加工零件产生的误差进行了分析，认为激光快速成形中的分层技术和树脂材料会引起尺寸精度误差，同时，分层技术还会引起螺旋叶片表面的形貌误差。Laser Rapid Prototyping which is used in tooling the complex parts of blood pump is a good way in designing and developing the micro-axial blood pump model. We present the fundamental and methods of rapid prototyping and study in molding the complex screw blade by designing and manufacturing the blood pump model. By analysis of parts errors caused by tooling, the errors of the dimension precision is caused by the technique of layering and the material of resin of rapid prototyping and the technique of layering causes the appearance errors of screw blades.
