快速成型（RP）过程是产品开发周期中一个成熟的领域。RP技术越来越多地被用作快速制造（RM）系统，主要用于生产定制的最终用途部件。与此同时，RP工艺中使用的材料的性能有所改善，因此可以用于此目的。这些材料之一是为立体光刻开发的环氧树脂Accura SI40。本文研究了短期老化对该树脂某些力学性能的影响。此外，通过该研究，表明在短期老化周期（即，24天）中，树脂中的固化量及其机械性能的变化将随着老化的进行而达到平衡。此外，通过采用热分析技术，即差示扫描量热法（DSC），这些结果已被定量验证。(c)2006 Elsevier B.V.保留所有权利。
Rapid prototyping (RP) processes are a well-established area within the product development cycle. RP technologies are increasingly being used as rapid manufacturing (RM) systems mainly for producing customised end-use parts. At the same time, the properties of materials being used in RP processes have improved so they can be adopted for this purpose. One of these materials is the epoxy resin Accura SI40 developed for stereolithography. In this paper, the impact of short-term ageing on some of the mechanical properties of this resin have been investigated. Also, through this investigation, it was shown that in a short-term ageing cycle (namely, 24 days), the amount of curing in the resin and the variations in its mechanical properties would reach equilibrium as ageing proceeds. Furthermore, by adopting thermal analysis techniques namely differential scanning calorimetry (DSC), these results have been quantitatively validated. (c) 2006 Elsevier B.V. All rights reserved.
