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

使用激光熔覆的增材制造（AM）具有取代许多传统制造工艺的潜力。工程部件是通过在表面上反复添加和融合薄层材料来制造的。复杂的三维形状可以实现低构件畸变和最小的热量输入。然而，主要的缺点包括昂贵的粉末的高损耗和粉末头的侵蚀。这是AM广泛应用于更广泛应用的一个关键障碍，特别是对于大型组件。先进激光技术公司（ALT）已经注意到这些限制，并将通过开发一种新型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.
