摘要
随着快速成型技术的进步,其研究热点转变到快速直接制造金属功能零件方面,应用范围也拓展到航空航天、医疗、汽车、模具等领域。针对选区激光熔化(SLM)技术更适合精密小批量金属零件的快速制造等特点,结合华南理工大学在该技术方面的研究进展,研究讨论了成型材料、成型工艺与过程控制、应用及其影响因素等,并对SLM技术现状、存在问题和发展趋势进行了分析。
With the development of rapid prototyping(RP) technology,the research interests change to direct manufacturing of metal parts with functions.The application fields of RP are expanded to the areas of aerospace,medical,motor vehicle,mould,etc.According to the characteristics of selective laser melting(SLM) applicable for rapid manufacturing of fine-structured and small-lot metal parts,powder materials,process,control,applications and affect factors are studied and discussed by combining the research work of the author′s group.The status-in-art,problems and developing prospect of SLM technology are also discussed.
