Test 1 with Iglidur i150-PF filament

prusaprinters

<p>This is my first test of a series with the filament of Igus: Iglidur i150-PF. <a href="https://www.igus.eu/product/12404">https://www.igus.eu/product/12404</a>.<br/> I used the following hardware:</p> <ol> <li>steel sheet with one layer of glue. (a steel sheet without coating)</li> <li>enclosed printer with ventilation control with an ambient temperature of 22C.</li> <li>0.6mm nozzle</li> </ol> <p>The results are not yet satisfactory. Tips for the printer settings are welcome to reduce the problems listed. See also the photos.</p> <ol> <li>Stringing and Oozing.</li> <li>Warping upwards of the sharp gear tips.</li> <li>String on the filament tip after unloading</li> <li>First layer separation (partly)</li> <li>Small holes in the draft shield (under extrusion?)</li> </ol> <p>See the next test 2 here: <a href="https://www.prusaprinters.org/prints/48793-test-2-with-iglidur-i150-pf-filament">https://www.prusaprinters.org/prints/48793-test-2-with-iglidur-i150-pf-filament</a></p> <p>I received an e mail from Niklas Eutebach from IGUS with recommendations. See below his mail. I will test this in test number 3.</p> <p>Hi Bas,</p> <p>thanks for your message.<br/> Based on the screenshots out of the slicer, my assessment is as follows:<br/> • speeds and cooling looks fine<br/> • 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.<br/> • 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.<br/> • 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.<br/> I hope this helps, if there are further problems please let me know.</p> <p>Mit freundlichen Grüßen / Best Regards</p> <p>Niklas Eutebach M.
