Next lesson's up: the planning and air-safety work we did before printing a single suit part. Same heads up, we're moving our videos into classrooms so they're easier to follow in order. If you've seen this one, scroll on by. This is the episode where we slowed down on purpose. We learned the printer first so we weren't guessing, picked the helmet as the starting point so a mistake wouldn't cost us the whole suit, and bought the Mark 6 files from Walsh 3D instead of modeling from scratch. Then the big one: air safety. The final suit uses ASA and TPU, which can put harmful particles in the air, and our monitor caught little spikes even with PLA and PETG. So I built a proper vented exhaust setup and tuned it with a simple paper towel test. The takeaway: if you print anything past PLA in your house, vent it properly. Plan first, print second. Do you track air quality in your print space? What are you using?
