My process for getting ai generated minis print ready on resin
Spent the last month dialing in a workflow for printing AI generated miniatures on my Saturn 3. Figured I'd share what works and what doesn't since I wasted a lot of resin figuring this out.
Generate the model in Meshy. I use image to 3D mostly because I can control the pose better by uploading concept art. Text prompts give me random poses that usually don't work for tabletop.
First thing in Blender is check for non-manifold edges. There's always some. Select all, mesh cleanup, make manifold. Then check wall thickness, anything under 1mm gets thickened or it'll break during printing or post cure.
Weapons are the worst offender. Swords, staffs, spears all come out way too thin. I usually just delete them and kitbash replacements from free STL weapon packs. Faster than trying to fix them.
Scale to 32mm in Chitubox, add supports manually. Auto supports miss overhangs on AI models constantly because the geometry is irregular. Manual supports take longer but save failed prints.
Print settings: 2.5s exposure, 0.03mm layer height for detail. Standard grey Elegoo resin.
Success rate after dialing this in is about 80%. The 20% failures are usually models with too many thin floating bits that I missed during cleanup.
Total time per mini from generation to printed: about 45 min of active work plus print time. Not counting the learning curve which was painful.
Worth it for custom campaign minis. Not worth it if you just want generic fantasy stuff, there's better STL packs for that.
