大多数快速成型（RP）技术都采用分层制造（LM）工艺来高效地制造3D物理模型。然而，使用LM会降低RP零件的表面质量，这是一个关键的缺点。因此，与表面粗糙度相关的主题一直是RP中的关键问题。本文提出了一种新的方法来模拟熔融沉积建模（FDM）中的表面粗糙度。基于FDM零件的实际表面粗糙度分布，考虑影响表面质量的主要因素，建立了表面粗糙度随表面角度变化的理论模型。通过实现和与经验数据的比较，验证了所提表达式的正确性。并对主要影响因素的有效性进行了分析和讨论。(C) 2009 Elsevier B.V.版权所有
Most rapid prototyping (RP) technologies apply a layered manufacturing (LM) process to efficiently fabricate 3D physical models. However, a critical drawback that reduces the Surface quality of the RP parts occurs by utilizing LM. Hence, topics related to surface roughness have been a key issue in RP In this paper, a new approach to model surface roughness in fused deposition modeling (FDM) is proposed. Based on actual surface roughness distributions of FDM parts, a theoretical model to express surface roughness distribution according to changes in surface angle is presented by considering the main factors that crucially affect surface quality. The proposed expression is verified by implementation and comparison with empirical data. Also, the effectiveness of the main factors is analyzed and discussed. (C) 2009 Elsevier B.V.
