Abstract A previously developed and verified thermal model for Laminated Object Manufacturing (LOM) was used to investigate the effects of various processing parameters on the temperature profile in a LOM part during the build cycle. The mathematical model, based on 3 -dimensional transient heat conduction in a rectangular geometry LOM part, allows calculation of the transient temperature distribution within the part during the application of a new layer as well as during other periods of the LOM build cycle. The parameters roller temperature, roller speed, chamber air temperature, base plate temperature, and laser cutting time were independently varied, and the LOM process response simulated. The results were analyzed in order to gain insight into potential strategies for intelligent process control. (Auth abstract) [References: 10]
