No, due to the nature of FDM. I can print on 100 micron layer height at excellent repeatability but there will always be slight unevenness and striation.
The best thing to do is acetone-mist it, sand it or even use a spray paint primer that will help fill in the tiny gaps.
Polyjet technology gives a very smooth finish on top oriented print surfaces where there’s no need for support and a slightly grainy or striated finish on bottom oriented surfaces that is easy to sand smooth. A spray paint will even everything out after with the color of your choice. Check out my hub for photos and don’t hesitate to send me an enquiry for more relevant examples if you’re interested. Good luck!
