【Abstract】 For consumer electronics features of fast updating speed and personalization,top-down design methodology and 3-D printing technology were adopted to achieve high-quality plastic housing of consumer electronics products,high-speed design,high-precision model accuracy and efficient molding.The skeleton model design method,the master model design method and its application range were elaborated.The general flow of desktop 3-D printing was described,three commonly used process model parameters were established.A mini speaker was taken as a case.The results show that the top-down design of consumer electronics and 3-D printing can improve the efficiency of design and model forming,and shorten new product design and development cycles.The case provides a reference for top-down design and rapid prototyping of other mechanical products.更多还原
