Hi Josue,
The best thing is to go after the company supplying the resin. They have to give that you. (If not you need to find a new supplier - )
Also try on IDES.

Thanks you

I try IDES , but doesnt show the Shrinkage, any way I already receive the answer from resin supplier, they also dont haveit like the std "technical data sheet",, so they anwer by email only as follow




3mm of tickness
0.022 - 0.019 in/in = 2.2% - 1.9% (from 50 to 70 MPa)

But if your product has thicker thickness, I would like to recommend as below.
0.022 - 0.017 in/in = 2.2% - 1.7% (from 50 to 70 MPa)

Good, depending on your part size be conservative on the numbers.
