Abstract of the presentation

Laser additive manufacturing (LAM) is a popular method for metal materials fabrication. Laser engineered net shaping (LENS), one of the laser additive manufacturing techniques, has recently gained increasing attentions due to its advanced capabilities for metallic parts fabrication, development, and repair. There are many advantages of LENS over conventional manufacturing techniques: No tooling or moulds required; Low cost in manufacturing of low volume components; Remanufacturing of hard-to-machine or high-value components in a cost-effective manner; Parts with highly flexible features can be produced. The presentation will focus on two topics: LENS of in-situ TiB reinforced Ti matrix materials (research for material development) and ultrasonic vibration assisted LENS of metal materials (research for process advancing). 

激光增材制造目前是一种非常流行的金属材料3D打印技术。其中激光近成型技术由于其在金属材料领域材料的制造,开发,和修补先进能力获得了很大的关注。传统的制造技术相比,这项技术有以下的优点:无需工具以及模具,低成本加工小批量组件,难加工和高成本组件的修复。这个报告将围绕两个主题进行:原位硼化钛增强钛金属复合材料开发,以及利用超声技术改善金属组件加工工艺。
