Shape Deposition Manufacturing (SDM) is a developing Rapid Prototyping technology in which mechanisms are simultaneously fabricated and assembled. As shown in this figure, the basic SDM cycle consists of alternate deposition and shaping (in this case, machining) of layers of part material and sacrificial support material.
|This cycle of material deposition and removal results in three key features:
The resulting mechanisms can have almost arbitrary geometry, embedded actuators and sensor and locally-varying stiffness properties, making them more robust and simpler to control.
