Generally this filament prints very nice, and it’s not cheap so when I run into an issue I like to try and understand what’s going on. Hoping someone can have a look at these photos to help me figure this out. These are angled supports and the inside on each is visually unappealing, but structurally seems fine.
I’m using a 0.6mm nozzle, bed temp of 110°, and a nozzle temp of 255°. The filament has been dried prior to use.
It’s clear from the photos that the first problem is related to too steep an overhang. Before experimenting with tweaks, I’d use a test model to save my filament by download one of the many overhang tests available as a test model.
Here’s a search term for that on Printables. These models print quickly and save filament, perfect for running quicker tests.
After running the first test with the current settings, I would then try it again with a known filament of another type. This will ensure there are no mechanical issues assuming that he other filament performs well, though based on the photo, I think that’s unlikely. Having a side-by-side comparison of two filament types can reveal a lot about your printer’s overall performance.
Once you have your reference setup, start varying the following parameters incrementally to see if they improve or worsen the outcome. Rerun the overhang test to determine where the issues occur, which seems to be around 60°.
As you likely know, it’s often a combination of settings that impacts the result.
Additionally, are you verifying the chamber temperature and ensuring no fans are running? That filament performs better in warmer conditions, such as 40°C or above.
Have you also tried changing the model orientation so the model lies flat to minimize concerns about overhang?
At the end of the day however, you may not be able to completely avoid this overhang issue without the use of supports.
