Pet-CF Printing Temperature and Nozzle size Question?

pigseye

Hi all,
Was wondering what is the ideal printing temperature you've been using for PET-CF for strongest layer adhesion?

Regarding Siraya Tech PET-CF, I've been successfully printing it through a hardened steel 0.4mm nozzle at 275 Deg C with excellent cosmetic print quality (Bambu P1S). But, I don't know if the layer adhesion is adequate for the SL-15 and SL-9.

Finally, is nozzle size for PET-CF primarily addressing clogging or are there other benefits such as improved layer adhesion when using a 0.6mm nozzle vs a 0.4mm nozzle.

Your insight is appreciated.

Thanks

Bumping my own question but wanted to clarify, I started at 295 degC for a printing temp and noticed the cosmetic quality was not as good when compared to other print temps. Finally just printed some benchies at 270, 275, and 280 degC at 50mm/s. I found that on my P1S 275 degC had the best print quality and the benchy hull just went to hell at 280 degC with waves and ripples. I didn't bother going higher in temp. This was using a 0.4mm nozzle.

Is this typical? or is my 280degC print an outlier that had some type of issue.

I see so many threads where people are saying the get good quality prints with PET-CF at temps much higher than 275degC.

Your insight is appreciated.

Edit - bunch of typos

Thanks
