This last weekend I let the club shoot up my pretty Potemkin, which has a mostly printed superstructure. Overall I think it held up pretty well. It's interesting what how small a target can get hit. The bollards are about 3/16" in diameter and I had at least 3 shot up like this one. There may have been more like this, but the entire bollard is missing in three other places. The hatch only sticks up 1/16" above the deck, yet it was clearly hit. The face of the turret took light damage. My two steam launches took a lot of hits. The other one was blown off completely and lost its stack. This one took two direct hits and never moved. The gunwale is slightly splintered, but easily repaired. The BB that glanced off the bottom of the hull still put a sizable dent in the wood superstructure. I lost 4 of my 12 air intakes, but they are pretty small and not expected to survive a direct hit. The stacks are also very light - just one thickness of plastic, about 0.42mm or 0.016". So I actually expected them to disintegrate when hit. The entry hole is pretty big, but the stack held up fine. So I'll use a single perimeter, no fill, to print superstructure for small ships that need a lightweight superstructure, like destroyers. The exit hole. Bigger, but a little thin CA and paint and no one will know. I got the splinter shields shot off twice. No damage to the splinter shield, so I need stronger glue. This picture shows that the dents to the 3DP structure was about the same as the dents in the wood (poplar) structure. I'm pretty pleased with how the 3DP superstructure worked. I can have a more detailed superstructure than I would normally do and still not be concerned about it being damaged, since I can just print more. Plus it was a source of entertainment at the battle... after each sortie we would gather around to see what had been shot off.
