Russian tanks typically have a pretty rough surface from that era so the finish doesn't have to be perfect. In fact, no tank surface is perfect even on modern tanks. It's a combo of sanding, filling, sanding, primer, sanding, primer, sanding....Guido Henn wrote: ↑Mon Jan 08, 2024 11:30 am Hello,
amazing.......but how do you get the surface of these 3d printed parts smooth to produce a proper paint job?
with kind regards,Guido
The parts that are printed in resin (bluish gray) have virtually no lines from printing so a quick light sand is all they need. I'm reprinting some parts in ASA (white) which holds details better than PETG so then they only need a light sanding before primer also. Having a printer that can print fast at a .08 layer height is also handy.
From now on structural parts will be done in PETG, small detail parts in resin, larger detail parts will be ASA, and rubber tires are simulated with TPU material. Tracks will be produced going forward from industrial grade resins that are very resilient.
