Original Post: 8\/29\/2020<\/strong><\/h3>\n\n\n\n

I’d worked intermittently on this design since I got my Ender 3 Pro, so about a year. I’ve always liked the Brooklyn Class, America’s answer to Japan’s Mogami class light cruises. And USS Helena<\/a>, with her stellar and active carrier in the Pacific, capped with a heroic, if tragic end, is my favorite. But when I tried to print her, I had trouble with her fine details in 1\/450 scale using my Ender. The searchlight tower and bridge structures in particular, either couldn’t be printed or the results look unimpressive at best. I knew I’d be getting a resin based printer eventually so decided to shelve my USS Helena project till then. <\/p>\n\n\n\n

My first LD-002r prints were tiny detail parts, I started getting more ambitious (and successful) while making resin parts for my second USS Texas project. After being amazed by the results I had pulled off on Texas 2<\/a>, I decided it was time to revisit my USS Helena project and here she is, done for now. I used the LD-002r to print everything except the main hull and stands. for those large parts I still used my Ender 3 pro.<\/p>\n\n\n\n

Reprints & problems<\/h5>\n\n\n\n

It’s odd that I don’t have a picture of Helena’s main guns hot off the printer to show. After all, I printed 4 sets of them before I had 5 decent turrets to use. For some reason they gave me a really hard time. Actually, I unfortunately had a lot of re-prints on this project. The 5 inch guns (also missing above) were printed three times and the aft superstructure twice… Below are some members of the reject parts collection.<\/p>\n\n\n\n

The semi cured resin build up problem I’ve written about in other posts, was the main culprit with the 8 and 5 inch turrets (though some parts lost bits during printing). The aft superstructure fail was my bad, I totally failed to adequately support a leading edge on the bottom with disastrous results. I usually have a feeling that I’m under-supporting objects when they fail but I find over supporting yields muddied results – there’s a fine line. Like Ive mentioned before, I find using the LD-002r and Chitubox requires a little finesse to get the perfect print. For me, it’s no where near as straight forward as using my FDM based Ender 3 Pro and Cura. <\/p>\n\n\n\n

Chitubox experience is half the battle<\/h5>\n\n\n\n

Knowing what works and what doesn’t in Chitu Box is half the battle. When to use heavy supports, when to go light. When you need to manually place supports and where. How to angle your part to end up with the least resin build up. How long to set your cure time based on resin used and printer. One feature I wish Chitubox had is an equivalent to Cura’s Layer View. There is no way to see what your printer will actually print in Chitubox. Cura’s Layer view has saved me from trying to print beyond my Ender’s abilities sooo many times. Chitubox has no such safety net. You just need to know from experience what your SLA\/DPL\/LCD printer can pull off.<\/p>\n\n\n\n

I am getting better…<\/p>\n\n\n\n
