Thermal Modeling of Heat Transfer within LOM Heat Roller used for Laminate Hot-pressing or Boding: 2D Axisymmetric Stationary Heat Conduction Model

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.

分层实体制造（Laminated Object Manufacturing，LOM）快速成型技术（Rapid Prototyping Technology，RPT）是一种高效且适用性优异的技术，拥有诸多应用场景。然而，其在木制品原型制造（wood product prototyping，WPP）领域的应用，尤其是针对微型薄木质工件——即各类木单板——时，分层实体制造热源产生的热效应会对最终三维木制品的质量构成挑战。因此，针对工件层合（零件构建阶段）过程中对工件产生热影响的工序与环节，即激光切割与层合粘接或热压，本报告是理解分层实体制造快速成型技术热压辊内部热传递过程的研究内容之一。
