摘　　要：快速成型机的小型化、低成本化是当今快速成型机技术的主要发展方向。现有激光快速成型系统使用的激光光源大都是气体激光器。针对现有激光快速成形系统使用气体激光器存在的缺点,研究使用半导体激光器或光纤激光器的新型能量源来代替气体激光器。提出了使用高功率半导体激光器线阵和高功率光纤激光器线阵两种方案,并比较了利用此两种方案作为激光快速成型系统能量源的优缺点。The main development tendencies of rapid prototyping technology are smaller dimensions and lower costs. At present, most laser rapid prototyping system uses gas laser as the laser source. Because laser rapid prototyping system using gas laser exists some flaws, therefore, to overcome the problems, semiconductor laser and fiber laser as the new energy source are studied to replace the gas laser in this paper. In this paper, the line array of high power semiconductor laser and the line army of high power fiber laser as two kind new methods are given. The two methods as the energy source of laser rapid prototyping system are compared.
