For all the people who have asked about filaments, here's my list, spread across 8 different posts. This list includes over a hundred filaments, with pictures, measurements, and impressions. All are 1.75mm. Please don't read too much into my opinions, there's a lot of variation in filament and printers, and my opinions apply only to the spools I have on hand. I try to be objective with these opinions, but my preferences and biases affect my opinion, so keep that in mind when browsing this list. Also be aware of the date, some of these filaments may no longer be available, or may be different from what is currently available. I sometimes describe how I use and print some filaments just to provide another data point, it's likely that your optimal setup will be different from mine.
