I think this is fooling ourselves. The cheap 3d Printer filament is fine.
Its weird because a mega corporation would consider the quality and if it meets the qualities, they would buy the cheapest price(with few other considerations, maybe china-US relations might deter).
In this case, the objective right answer is to buy the cheapest when it comes to 3D printer filament, as long as it meets the quality. It does.
I wonder if its some emotional decision to buy a more expensive product that performs equally.
