Can we get a pro to consolidate some info into this thread for us?
Step one: get a printer and the programs your going to need... What are they and what are the alternatives? Pros and cons of each.
steps after this i have no idea im a total noob and dont even know what to research to get to a functional point.. HALLLP
I would recommend going with an inexpensive small scale printer like the ender 3 pro, which is like 189$, to learn on. You'll need some form of modeling software to cut up models and a slicer software. For a modeling software I recommend blender because it's free and there are a lot of tutorials out there for it and it's relatively easy to cut up 3D models in it. Next you will need some sort of slicer. I've used Cura, which is also free, and I haven't had any issues with it. Most importantly you are going to need a computer that can handle the modeling and slicing software, be prepared to wait on large models no matter what computer you have though. If recommend starting with PLA filament because it's pretty inexpensive, you don't need an enclosed printer like you do with ABS, and its not as tempermental about temperature changes while printing like PETG (from what I've heard). I don't recommend getting a large printer like a CR10 S5 to start even though it can print full helmets and chest pieces at a time. I completely recommend working your way up and doing at least one suit on a small scale printer to learn FDMs problems and what prints look like as parts begin to wear out. If you want to look at what cutting apart a model looks like with blender I just made a video that shows a brief explanation of it. Feel free to ask me any questions I'm on the forum pretty much daily!
