As I understood you postcured BlueCast Resin?
We always suggest to avoid postcuring, because both UV and heat inside oven will shrink delicate patterns like filigree.
Adhesion issues are not due to shrinking during print, but are due to the high content of polymers that help sublimation and burnout.
in order to avoid unpredictable shrinkage:
- do quick baths into alchool and dry with air asap
- avoid exposing models to heat/uv
- prepare cylinder asap
Worst to do is to leave models submerged for minutes into alchool, it will solve polymers inside resin matrix and take place of them, when it evaporates you get a pattern contraction…
Feel free to contact me for support about those issues, also in private.
