I’m not sure that a survey even CAN provide an objective result.
Different printers, different models printed, different climates, different settings subjectively evaluated by people who usually have no comparison to base their evaluation on.
@Marcus_Wolschon The survey is just the start of the process - the most recommended will then be tested (in a more precise fashion I am sure)
In absolute terms you are right. Yet, if we get enough responses, we get something like a Delphi Pool that can give us a good idea of where to start a more rigorous study. One filament manufacture I have talked with has done tests on many other suppliers and could help here
I recently bought some through Micro Center online because it was cheap and a new source. Turned out it didn’t print well for me. Was undersized and my gear would not grab it. I’m going to have to give it to someone or maybe use on my old printer or take my extruder apart and see if I can make it grab better. It measured at 1.73-1.74 and I usually use 1.76-1.78
