I tried to figure out where that figure was from, and spent about an hour or two watching CNC Kitchen videos on Youtube. What a ridiculously inefficient way of sharing test results!
I guess Youtube makes it easy to monetize your work, but as someone interested in results, this is rather frustrating.
So higher than normal flow, high temp, slow feed rate, and very little cooling showed remarkable strength along layer lines, up to 93% of horizontally printed specimens.
That blog post is even more frustrating than the video. No structure, you need to read a giant wall of text to figure out the result, at that point it's probably faster to just watch the video.
I hate that so much info about 3D printing requires watching hours of videos (even if the videos are just 15 minutes long, you'll end up watching a bunch of them because you don't know which ones contain the info you are looking for)
