I have many of the Chinese 3D printed ships, both ssmodel (gray resin) and Gaga Model (pinkish-orange resin). I much prefer Gaga because the hull halves fit so well together that you can barely see the seam, even without putty. The earlier ssmodel kits are a different story. They had blocks of resin (casting blocks) at the end of the hulls that would have to be removed but then you have to sand the ends flat to minimize the gaps to fill with putty. However, I could not resist one of their latest releases, the 1918 HMS Glorious. It has a much improved ends of the hull halves. The thick casting blocks are gone and replaced by casting sprues, which are far easier to cut and sand. I just don't know which to build first, the Gaga Model 1915 HMS Barham, HMS Iron Duke or ssmodel HMS Glorious, however, the Glorious has three hull parts instead of two with the other the kits. Other ssmodel kits have three, four or six hull pieces that sure to be a pain to sand and smooth.
