Elegoo Grey resin shrinkage

[Vasilis]

Hallo everybody
I use so far Elegoo grey resin and i see in my models that i have a significant shrinkage. Is there any way to prevent it?? The exposure time is 14s, 0.04 thickness, 9 bottom layers and 70s exposure for them

I have it on good authority (forgotten from where ) that there is approx 7 percent shrinkage on curing and this is inevitable! I have been calculating this into my design as I need accuracy for an N gauge railway. With variable success!
