Research and Discussion on Large-Scale Laser Powder Bed Fusion Metal Additive Manufacturing Equipment
-
摘要: 国产金属增材制造加工装备已在航空航天、军工、汽车、模具、高端医疗等先进研发制造领域获得广泛应用。伴随着大尺寸增材制造的需求逐渐增多,突破国产化大型金属增材制造装备及工艺技术的瓶颈,提高大体积、高品质金属零件增材制造成形加工的制造水平,在缓解金属增材制造成形范围、工艺质量和应用细分等方面将起到一定的促进作用。本研究结合目前大尺寸金属增材制造装备日趋广泛的市场需求,针对激光粉末床熔融金属增材制造装备的技术特点,探讨了大尺寸、多光束装备制造,以及使用成本与效率问题,并对具有“飞行打印”结构超大尺寸装备的技术思路进行了介绍。Abstract: The domestically-produced metal additive manufacturing processing equipment has been widely applied into the advanced research and development manufacturing field such as aerospace, military project, automotive, molds, and high-end medical care. As the demand for large-scale additive manufacturing gradually increases, overcoming the bottlenecks in the domestic production of large metal additive manufacturing equipment and process technology, and improving the manufacturing capabilities of the large-volume, high-quality metal parts in the additive manufacturing will play a significant role in alleviating challenges related to the forming range, process quality, and application segments of metal additive manufacturing. Combining the growing market demand for the large-scale metal additive manufacturing equipment and addressing the characteristics of laser powder bed fusion (LPBF) metal additive manufacturing equipment, we discuss the manufacturing of the large-scale and multi-beam equipment, as well as the cost and efficiency. Besides, we provide a brief introduction to the technical approach of super large-scale equipment with a "flying printing" structure.
