Trust but verify: There are a lot of filament manufacturers out there, and I think every one has its own set of lovers and haters. I will not be naming any specific brands because I want this to devolve into a X vs. Y conversation. I think you should read the reviews and feel safe in going with brands with a good reputation. But, you should also experiment. I have had some bad experiences with filament from brands with stellar reputations. I have also had some great results from brands that had zero reviews on Amazon. There are so many variables that lead to a successful or failed print.
