>watch YouTube videos on how other people make big props - Tested and Punished Props come to mind >cut the models in your 3D program, add any kind of registration between cut faces that you can
>use ABS if you can, it's far easier to sand
>print your models efficiently with as little support as possible
>use the strongest adhesive you have available to you to put pieces together - ABS slurry with ABS prints, JB Weld, etc
>use metal hardware where possible, even if it's just makeshift pins in adjoining faces
>fiberglass reinforcement is a good idea for anything you can fit it inside of
>fill seams with Bondo, spot putty, Green Stuff, or my favorite, super glue gel + Zip Kicker
>sand and file for at least 100 years
>filler/high-build primer is your best friend
>XTC3D/epoxy resin topcoat is a meme but used wisely it can save some time on broad areas, it can also add a degree of strength
>print, sand and paint detailed parts separately; attach them later
>layers and textures take your props (and costumes) to the next level
>don't rely on 3D printing for every part of your prop, using bought or found materials can save time and look more convincing

These are all the tricks I can think of that I use whenever I print something big.
