I've been using ColorFabb PLA/PHA for every day printing on my UMO for a while now. I like the reduced brittleness and increased toughness and it's all been high quality.
UM included a roll of Tough PLA with my S5, and so far it seems nice as well, but I'm not familiar enough with it yet to make a detailed comparison.
Has anybody found any significant advantages for one over the other?
I need to buy some more filament soon in different colors and I was planning to stick with PLA/PHA for my everyday printing needs because I'm familiar with it, it's a little cheaper, and it comes in many more colors, but I thought I'd check in here to see if anybody had any compelling reasons to switch.
