A CRITICAL REVIEW OF PROCESS PARAMETERS IN LAMINATED OBJECT MANUFACTURING PROCESS

Abstract

Laminated Object Manufacturing (LOM) is one of the sheet lamination additive manufacturing processes used to manufacture 3D solid object with the help of sheet lamination process. A formerly developed and verified model of LOM was used to study and find out the effects of various process parameters on the temperature profile in the part during the build cycle in this process. The process parameters i.e. roller speed, roller temperature, cutting time of laser, air temperature of the chamber and the base plate temperature were varied independently and their response on the LOM process is noted. This study also presents an analysis of one of the major problems occurred in LOM process i.e. warping and an optimal combination of these process parameters to reduce this warping effect.
