Thermal Modeling of Heat Transfer within Copper Heated Roller of Laminated Object Manufacturing Apparatus: Accumulated Heat, 2D Axisymmetric Transient and Stationary Heat Conduction Models

Laminated Object Manufacturing (LOM) is an efficient rapid prototyping technology (RPT), a suitable technique with many applications. However, its application for wood product prototyping (WPP), especially in micro-thin wood objects, namely different types of wood veneers, the thermal heat effect emanating from LOM heat sources, challenge the quality of the final 3D wood products. Therefore, regarding the parts and processes, which thermally affect the workpiece during object lamination (part-building phase), namely laser cutting and laminate bonding or hot pressing, this present report is a part of the understanding of the heat transfer (heat accumulation, transient and stationary heat conduction) within the LOM heat roller used for thin laminates bonding or hot-pressing.
