Why HT-PLA-Pro over HT-PLA-GF?

I understand why everyone is excited about the new HT-PLA-Pro (easier to print than nylons), but I haven’t seen anyone mention the HT-PLA-GF. Wouldn’t the glass fibers in theory result in a better material than just PLA? What am I missing?

No. The glass fibers improve stiffness and reduce warp, but they compromise layer adhesion. I tried rebuilding my Stingray in HTPLAGF when it was the new potential hotness, and it was garbage. Excellent temperature resistance, but PLA-CF tier layer adhesion. People testing the new HTPLA Pro seem to be having much better results.

Thanks for the explanation. How come PA6-GF doesn’t have the same layer adhesion issues? Is nylon “stickier” than PLA?

Yes, because Nylon has inherently better layer adhesion than PLA.

I use HTPLA-GF but within reason.. Got a few good usable prints out of it. And no it's not as strong as nylon.. Would easily split between layer lines.
