Prototype Development of a Hybrid Gas and Ultrasonic Powder Delivery Syste,

利用激光熔覆的添加制造(AM)有可能取代许多传统制造工艺。工程零件是通过在表面反复添加和融合薄层材料来制造的。复杂的3D形状可以以较低的组件变形和最小的热输入来实现。然而，主要缺点包括昂贵的粉末的高消耗率和粉头的侵蚀。这是将AM更广泛地应用于更广泛的应用程序，特别是大型组件的关键障碍。先进激光技术(ALT)已经注意到了这些局限性，并将通过开发一种新型的混合气体和超声波粉末输送系统来解决这些问题。

Additive manufacturing (AM) using laser cladding has the potential to replace manyconventional manufacturing processes. Engineering parts are created by repeatedly addingand fusing thin layers of materials to a surface. Complex 3D shapes can be achieved with lowcomponent distortion and minimum heat input. However major drawbacks include a highwastage of the expensive powder and the erosion of the powder head. This is a key barrier tothe wider adoption of AM to a broader range of applications particularly for largecomponents. Advanced Laser Technology (ALT) have noted these limitations and willaddress them by developing a novel hybrid gas and ultrasonic powder delivery system.
