Experimental Design and Parameter Optimization for Laser Three-Dimensional (3-D) Printing
X-Y. Chen, Q. Gao, X-L. Wang and X-D. LI

Laser three-dimensional (3-D) printing is a novel manufacturing process which builds the truly 3-D structures by solidifying the liquid resins in a layer by layer fashion. In this work the ESSIL 296 resin was applied in manufacturing objectives in centimetre dimension with an in-house manufactured rapid prototyping machine. Some groups of experiments were implemented and orthogonal experiment was used to analyse the experimental results. Optimized laser power, laser scanning speed and resin operating temperature have been obtained.
