And that consideration may be part of why no one is stocking "in depth", because this stuff absorbs moisture. O of the things I noted when I opened up a roll of white PLA was that the other stuff comes vacuum sealed in a heavy poly bag with a pill bottle sized bag of dessicant, this white had a big bag stuffed into the reel core with about 4 or 6x the silica gel the cheap stuff comes with. > If anyone has a good source of quality 3D printing filament at a good > price, particularly TPU, I'd love to hear your suggestion. I'm still trying to control adhesion, I am damaging the glass chiseling my prints loose. I do have 2 of these drive things running now, and I was going to try a 40C bed at 190C for the last flexgear, but that still blocked the flow, and it wasn't till I warmed up the extruder to 210 that the flow motor stopped complaining. Thanks for any hints on how to reliably control the adhesion with white PLA. Its sticking way too good.
