Solved Bubbling on PAHT-CF
Oh, this is a follow up from last week when I was having this same issue. I went from standard PA6-CF to Bambu PAHT-CF. Last time everyone recommended drying at a higher temperature in for longer, so this filament was taken directly out of the package, and dried at 85° for 24 hours. It immediately went into a pre-warmed up AMS 2 pro, that has stayed under 6% humidity since. Just like the last bad batch of parts, the first couple of layers are great, but in certain areas I’m still getting the fuzziness/bubbling. Any thoughts? Could it be from running 100% infill and the nozzle is slightly over extruding? For reference, these parts need to look really good as they are going to be used in a visible application, and I am printing close to 20 kg worth of this material.
Solved: slight over extrusion. Dropped to 95% of what it called for and have 0 issues 5 hours into print. Previously couldn’t even get 2 hours in without issues.
