New Black Resin (version 4) very soft?


we just got a batch of version 4 black resin and the prints turned out to be very soft, nearly as soft as the flexible resin.
With version 2 black resin printed hours before we didn`t had this problem.
Preform and printer softw<are/firmware are up to date.
Did anyone else experience similar problems?


Is it flexible after post curing?

Yes, even after post curing the material is softer than the V02 material.
The post curing makes the material a just bit harder.

Same issue here. V4 Black resin. Printed a lot of pieces, and it seems that only small ones stay soft, and when part is big enough there are good chances it will be hard (but not always).
