The issue with 3D printed parts is they are NOT sealed surfaces (even the SLS, SLA, DLP variants).
The way to get around this is to coat the surface/ soak the part (in a sealable bag if part is small enough) with epoxy and sand smooth then I think from there it is the usual moulding process.
This is my understanding of it, but happily to be corrected.
Cheers,
David
