Test 1 with Iglidur i150-PF filament

This is my first test of a series with the filament of Igus: Iglidur i150-PF. https://www.igus.eu/product/12404.
I used the following hardware:

1. steel sheet with one layer of glue. (a steel sheet without coating)
2. enclosed printer with ventilation control with an ambient temperature of 22C.
3. 0.6mm nozzle

The results are not yet satisfactory. Tips for the printer settings are welcome to reduce the problems listed. See also the photos.

1. Stringing and Oozing.
2. Warping upwards of the sharp gear tips.
3. String on the filament tip after unloading
4. First layer separation (partly)
5. Small holes in the draft shield (under extrusion?)

See the next test 2 here: https://www.prusaprinters.org/prints/48793-test-2-with-iglidur-i150-pf-filament

I received an e mail from Niklas Eutebach from IGUS with recommendations. See below his mail. I will test this in test number 3.

Hi Bas,

thanks for your message.
Based on the screenshots out of the slicer, my assessment is as follows:
• speeds and cooling looks fine
• with a 0,6 mm nozzle, in my experience the extrusion temperature can be lowered below the recommendations. I've printed at 225-230 °C. This will also aid with stringing. Also lower the initial layer temp (235-240 °C), this might help with too much adhesion.
• for cooling, the fan setting can be raised, also printing multiple parts at once helps a single part to cool down more and keep its shape.
• Depending on the filament's age and storing conditions, it might be necessary to dry the material to get the best result. Dry at about 65 °C for at least 4 hrs. in a hot air oven or vacuum dryer.
I hope this helps, if there are further problems please let me know.

Mit freundlichen Grüßen / Best Regards
