I have used the new “3D texture” feature in Solidworks 2019, which is basically bump mapping except it actually generate a 3D mesh so it is really visible on the part. You’ll have trouble getting the exact same surface as an SLS print, but you can get close.
The results visible in this thread are pretty rough, I’m sure you can get the printer to resolve a finer texture.
On the other hand I don’t know if you’ll be able to get the same texture as an SLS print with sand-blasting either. Maybe if you’re using custom medium that is able to create sharp geometries, but it may not be worth the time investment.
If you don’t mind, what’s your end-goal ?
