    how well will the SS stand up to both fast and big gun caliber rounds? have there been tests yet or are there plans to test it? It sure looks pretty that is for certain :)

    It's going to be tested against Lion's twin stern guns this weekend. But the outer shell is thicker than 1/8" ABS. I had two cranes on Lil Scharnie at Nats 2012 made from a piece of 1/2" wide, 1/8" thick ABS, and they took a lot of hits, and those pieces were unsupported, and narrower towards the ends. They are still in use today, having taken more hits since then. With the Malaya SS being 4mm thick on the outer shell, and being backed up with a 60% infill pattern (not quite solid but a lot of support), I'm expecting it to do very well. I will have a separate thread with pics after testing. (It better stand up well, I've been working on the CAD file for USS Connecticut's hull for weeks)

    And if it breaks you just print another. :)

    I've shot printed ABS before with a fast gun cannon, it dented but otherwise held up. Solid fill, roughly 3/16" thick. It was just a piece of scrap that I got, never used it for battle or anything like that. Printed ABS may need to be sealed especially if it isn't 100% fill just so it doesnt pick up water and add weight as it isnt always water tight and water can be drawn into the interior/space between the printed "strands".

    As part of post-processing, it's getting treated with an acetone vapor bath, which will melt and seal the surface, and make it nice and shiny. Also penetrates the pores and gaps nicely and helps to seal them. Solid fill would be rediculously time consuming in the print phase, even with a Rostock's printing speed. BTW, parts have started arriving for the build, and my wife is buying me the stepper motors for it for my birthday in a few weeks :) Good wife knows to ask the nerd for part numbers and the website to buy them from :) I am blessed.
