These ship models are purely 3D printed. Mostly FDM. This is an execise in patience... needed to eliminate frickin layer lines. ;) I experimented with various types of techniques using putty, primer, catalyzed resin and photo resin... ended up using TAMIYA BASIC TYPE GREY ;) Everything is finished and weathered using Armored Komodo acrylics. I scaled everything to vintage Kenner SW figure specs.
