Dear dear Trevor.
I have like these big ass printers and I like to slice them to itsybitsyteenyweeny bits instead.
SOOOO much more logical.
Seriously, I prefer one-part prints if possible, two parts if need be. It's so much easier in terms of afterwork and parts tend to get stronger too, although as you undoubtably have noticed ABS welds are "pretty strong".
I can even do a complete "shield part" of the shoulder on that machine as a one part, sized to original Carterbuilder specs. It JUST fits the build platform of this machine as the arch of the shoulder shield follows the cillindrical buildspace as if "made to do it". That part is done in 2 parts though, cause the amount of support needed for the piece that goes around the arm and which would kinda "hang in space" during print would be non sensical. I've noticed I could do complex tree-type supports with Netfabb2017 but I'm not too comfortable about those thin "smart supports" : they don't need too much to horribly fail yet I do have to take a very close look at how this "advanced support system" really works. I wouldn't feel too comfortable using them on a Prusa style machine due to the vibration induced be the moving bed, nor is a Delta the best idea unless it's really well callibrated (in terms of bowl/dome errors) but on a something like a Makerbot/Qidi/Flashforge/Ultimaker style of machine ? It could be very interesting.
But if you REEEAAAALLYYY want, I can print them in parts just like you'd do on a Wanhao I3 or an original Makerbot.
Just "say the word". Because as you might have guessed : those are YOUR tigh pieces.
By the way, atm, I've got 2 machines working for you. One's doing the armor, the other one is redoing the MA5D parts which I wasn't happy about. After swapping out the low cost hotend by an original E3D didn't do much in terms of quality, I redid the full mechanicals on the Hatchbox and the difference in output was just too much to ignore.
My biggest machine (still in callibration stage) can do 400x400x400 builds. Although I called the one above "massive build size", this is acutally the second _smallest_ machine I have ever build, and it will become my _smallest_ machine this year as I'll be rebuilding me current smallest one (220x281 buildspace) to an slighty higher version aiming for 220x500-ish, so it would be the ideal version for gun props and such. The idea is to have a full overhaul, keep the x-y axis parameters, extend the Z axis and swap out the Marlin/Ramps by a Smoothieware board.
And honestly ? I've NO idea atm if I can pull it off : a great deal can go wrong trying to do that.
