Recently I purchased a LCD resin printer with the idea of printing parts for some of the prototypes I am working on.
The resin I am using is marketed as "low-shrink" however after the parts being fully cured they shrink with more than 1%. The shrinkage is inconsistent and unpredictable because as it largely depends on the geometry. It is practically impossible to make any usable parts.

Do you know of any well tested resin suitable for dimensionally accurate applications?
