This a thread to discuss ideas how we might go about printing an entire ship. Each idea shared that works, or doesn't work, will help the community as a whole advance the state of the art of ship making. I first looked at printing a complete ship in sections. But I didn't like all the support that would be needed and the longer prints are more likely to go wrong. After thinking about it a while, I concluded that the best way may be just to print all the parts separately and assemble it like a plastic model. This has the advantage of being able to pick the best fill % and print orientation for each part. It may even be faster, but there would be a lot more individual files. The individual parts route didn't really seem to take advantage of the printer capabilities, so I'm working on a slightly different plan. I'm planning to print the sub-deck and ribs together, the bottom solid area with integral water channel, and a separate deck with most of the superstructure included. Individually printed pieces would include motor mounts, pump, servo mount, and superstructure parts (like the stacks) that I would expect to need frequent replacing. I'm using a M-class British destroyer as my test case. It's 23" long by 2" wide. Not really a practical model, but if it only has propulsion and a pump, it would make a great 38 knot convoy ship in Treaty. Of course my goal is to arm it with an accumulator and spurt gun. It's good to set challenging goals. Because of the length, I need to partition it length wise into 4 pieces to fit on my printer. The first test print is the bow section. Below is a picture of the sub-deck and ribs. I also had the bottom piece with slots for the ribs, but I seem to have misplaced it. I had some serious lifting issues and stopped the print before it completed. Even so, it looked like it would work. The ribs are 4mm wide - that seemed to be better compromise than 3mm or 6mm - and are decently strong. I was able to break them off, but it took a little effort. If they were brushed with acetone they would be even stronger.
