SLA-EPOXY SL5170, parts become softer after a few weeks

We have a problem with parts we build with the SLA 350 with EPOXY SL 5170. The
parts become softer and softer after a few weeks or a month. They become like
elastic. 3D-systems sad that it is a problem of the epoxy, the builded parts
pick up water from the air and because of that they loose the strongness and
become softer.
Who has solutions or suggestions to solve this problem or to let the parts be
stronger for a longer time.
