Description

Laminated Object Manufacturing (LOM) Rapid Prototyping Technology (RPT) is an efficient and 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 within the heat roller of LOM RPT.
