Abstract: The effects of process parameters on density of the part prepared by Selective Laser Sintering (SLS) were modelled, using an Artificial Neural Network (ANN) with a feed forward topology and a back propagation algorithm. The inputs of the ANN are the process parameters, including layer thickness, hatch spacing, laser power, scanning speed, temperature of working environment, interval time and scanning mode. The output of the ANN is the density. The experimental investigation results show that the ANN model may be used to analyse the relationship between the process parameters and the density of the SLS part quantitatively.
