The guardsmen were printed from scans of the original 80s plastic kit the ogryns are scans of the 90s metal ones and the commissar is from cults3d.
All printed on an Ender 3 with a 0.2mm nozzle (apart from the bases, they used a 0.4mm nozzle, I’m not insane).
What scanner are you using to get that level of resolution?
I’m afraid I didn’t do the scanning. That actual scans I managed to get were better than you can see here, they still had the mould lines on! If they were printed in resin they would be nearly indistinguishable from the originals.
Sadly I think they got DCMAed.
