The research of deposition process is the first step in development process of multi materials selective laser sintering.The deposition process enables to settle multi materials powder in horizontal formation on one layer. In this research weuse low frequency (70 - 200Hz) to vibrate a hopper nozzle in which powder is settled. The research method consists oftwo steps, the first step is to determine flow-ability parameters and the second is to join flow ability parameter withother parameters such that the line width can be controlled. The results show that the line width depends on uniformityof particle size, particle size, frequency of vibration, deposition gap, particle shape and feed-rate of hopper-nozzle.
