中文摘要：

提出了一种新的基于超声波焊接技术的快速成型方法。它是采用薄片材料，如金属、塑料片材或带材等，进行逐层加工，先采用超声波焊接，层层之间的结合实现固体连接，每一层焊接完成后，根据CAD数据信息，驱动刀具进行平面加工，然后再堆积加工成形新层，直至完成零件与模具的制造，实现了一二一种新的精密高效低成本加工与成形技术。使用鱼骨图分析了影响成型件产品质量的各种因素。

英文摘要：

A new method of rapid prototyping and manufacturing based on ultrasonic welding was put forward, which uses filmy stuff, such as slice of metal and plastic to machine the part layer by layer. By using ultrasonic welding to joint every layer with solid, using milling cutter to machine the part within the plane body according to the CAD information after the first step, then heaping the layer that is already completed, and repeating the former step until all the finish of the part, this method realizes rapid prototyping and manufacturing with high efficiency and low cost. The factors which affect the quality of the part was analyzed with the fishbone.
