In general, most all of the photopolymers continue to cure/change properties over time if continuously exposed to UV and/or moisture (acrylates worse than the newer epoxy based materials). This can be evident in clear parts right off of the machines that yellow over time. The newer epoxy based materials are much more stable and have less moisture sensitivity than previous materials but still can become embrittled over time. Some worse than others.

Has anyone any information on whether the VisiJet materials are affected by ageing? I have been using the crystal material and have a suspicion that it becomes more brittle over time.
