System development of adaptive spraying paths for rapid prototyping

Traditional rapid prototyping (RP) uses one nozzle, with a single-diameter, to conduct spraying of a RP part. The process is usually time-consuming and inefficient. To improve the traditional method, this research aims to develop a new approach by planning an adaptive path and applying it to the spraying process of every slice. Each accurately sprayed slice then adds one upon another to form a RP part. The processing includes four steps, which will help to produce the adaptive path file, which can be input into the RP machine to make a prototype.
