The thing is, by and large, we're already almost "post scarcity". We have no problems requiring technical solutions; we already have the tech. There's no polio that requires Salk. We've solved most of our problems, we just don't like the solutions.
Better tech won't fix that because that's not a tech problem.
It was just normal PLA. The only special filament was some TPU, but that was <10g total.
This is helpful, I think it's one of 3 things based on your input:
Edit: I think the fix/verify for scenario 2/3 above might just be trying the new nozzle after drying the filament. IE: If the filament is confirmed dry and still causing issues, then I try the new nozzle (after calibrating) with the confirmed dry filament. If that works fine then it was nozzle that was screwy (although the cause could have still been wet filament and me screwing it up unclogging?)
