Is there a shrinkage between the resin size and the cooled investment casting size?

If these are going to be operational I am definitely in for some type Fs!

Hi folks. Here is a small test run of Type E & F couplers in
castable resin. I plan to investment cast them in ZA-12 over

prints run in ABS resin worked perfectly.

Fingers crossed!
