快速成型是近十年发展起来的一种先进制造技术 ,采用此项技术可以显著缩短产品投放市场的周期 ,降低成本 ,提高产品质量 ,增强企业的竞争能力。以华中理工大学开发、生产的HRP系列分层物体制造 (LOM)快速成型系统和HRPS系列选择性激光烧结 (SLS)快速成型系统为例 ,介绍了快速成型的原理。指出快速成型技术在石油机械制造领域中的应用有新产品研制阶段的验证、新产品投放市场前的调研和宣传、快速制模、小批量与特殊复杂制件的直接生产 ,以及新材料的研究等 ,并给出了应用实例。快速成型技术目前还存在系统价格昂贵、加工精度较低和机械性能较差等问题 ,须着力解决 Rapid prototyping is a kind of advanced manufacturing technology developed in recent ten years. Using this technology can significantly shorten the product launch cycle, reduce costs, improve product quality and enhance the competitiveness of enterprises. Taking Huazhong University of Science and Technology developed HRP series LOM rapid prototyping system and HRPS series selective laser sintering (SLS) prototyping system as an example, introduced the rapid prototyping principle. It is pointed out that the application of rapid prototyping technology in the field of petroleum machinery manufacturing has been verified in the stage of development of new products, research and publicity before new products are put on the market, rapid prototyping, direct production of small batch and special complex parts, and new material research Etc., and gives the application example. At present, rapid prototyping technology still has some problems such as high system cost, low machining accuracy and poor mechanical properties, which must be solved
