I recently completed, and posted on the modelswarships.com site, the 3D-printed 1/350 SSModel Italian battleship Andrea Doria. This kit's hull was very nicely done in just two sections, which fit together perfectly. I recently received their 1/350 battleship SMS Helgoland, whose hull is printed in three sections. The Andrea Doria was in orange resin, with many cross-bar structures inside the hull to make it stronger; the Helgoland is in dark grey resin and the hull sections are completely hollow, though seem to be quite strong. At least the Andrea Doria came with some assembly illustrations; the Helgoland box had absolutely none, and the deck planking looks very much overscale, while the hull sections have what look like circular life preservers around every porthole. The real ship had the portholes entirely recessed into the hull and only light "eyebrows" above them. This will require a lot of sanding and cleanup to bring it up to a decent standard of accuracy. This company has some surprising variability in the accuracy and ease of assembly of its kits, even if they do represent first-of-their-kind ship models in this scale.
