My GoTo filament
This is my GoTo filament for Higher Impact, UV resistant, Outdoor projects. I do no have any 3D printed items that remain outdoors 24x7. But I do have items that are outside for hours at a time. HT-PLA Pro prints just like PLA, if you use the Polymaker settings provided in their filament profile.

I have purchased a few spools of HT-PLA Pro and honestly, I don't want to use anything else. This stuff prints beautifully with fully calibrated and its incredibly resilient. I've had it in a desiccant pod for my AMS HT while drying out some filament and it had no warping. The blue is a great color too. 10/10 would and will buy again.
