After the hull was ready to print, we continued with the base of the deckhouse. On the one hand, this base represents the point which rests on the hull and transfers the weight of the deckhouse into the hull and, on the other hand, carries the structure of the deckhouse itself.
The deckhouse will have a total length of 1.73m. In addition, it will be significantly lighter than the hull itself. In addition, the decks, which include the balcony cabins, are thinner and the deck from deck 11 is significantly wider again. This means that deck 12 and the decks above it protrude beyond the decks.
In the case of ships, the center of gravity must be as low as possible. Basically, the lower the center of gravity, the easier it is for the ship to right itself or roll (tilt) less and be more stable in the water. The fuselage itself is very stable and quite heavy. The printed hull itself now has a total weight of 6.4kg and will displace an underwater volume of 17-20 liters. This results in a later total weight of the ship of 17-20 kg. Most of the weight is placed in the hull in the form of ballast. The batteries can make a good contribution to the weight, provided they are heavy lead-acid batteries. I will write later in a separate post on the subject of driving electronics and which batteries I use.
All in all, heavy objects at the top of the ship ensure that the center of gravity moves up. This will also happen conditionally, since both of the ship's pools are at the top of deck 12. These pools will also be given special weight, as I plan to fill them with epoxy resin. The pouring out and more about the two pools will take place later and then again in an extra post.
The deck 5 areas form a kind of foundation which is designed to fit into the pre-printed areas of the hull.
So that the base parts of the foundation fit better later and everything fits together well, I also planned the front of the deckhouse including the bridge as part of the base. The front of the deckhouse will also be a little bit more stable and will form the beginning of the bracket for the balcony cabins.
First I planned the deckhouse front in such a way that the bridge becomes a fixed part of the deckhouse. However, the bridge was already very complicated in the planning and really challenged me. In addition, the front part of the deckhouse has a few steps due to the raised bow, which ensures that the deckhouse will not have a straight base. This makes printing a bit of a challenge for me and later for the printer as well.
The next post will continue with the deckhouse front. There was a lot to think about here. In addition, the question arose as to how I could best solve the bridge and how it was solved in the end.
I hope I was able to entertain you a little with the post. If you are interested in a discussion, then comment on this or other posts. I'm happy to hear your opinions.
