Print settings

FDM printing is recommended for the hull and large structural parts using PLA or PETG at 0.15–0.2 mm layer height with 20–30% infill; resin (MSLA) is strongly advised for small detail pieces such as radar dome, weapons, lights, and fender rings to capture fine surface detail. Print the hull halves flat on the build plate to avoid warping; cabin and superstructure parts may need supports on overhanging edges. Sand and prime between parts before painting dark navy blue to match the reference livery.
