Help, best setting for PolyFlex from Polymaker


Recommended Posts

Posted · Help, best setting for PolyFlex from Polymaker

I entered the material data on the package into Cura and estimated the other one not found:

Density: 1.22 g/cm³

Diameter: 2.85

Printing temp: 223 °C

Build plate: 60 °C

Retraction: 2.00 mm

Standby temp: 175 °C

Fan speed 20%


When printing small objects all is fine, but on larger ones (base size 107x50mm) the problems already occures on the secon layer.
The flow is almost nothing and there is virtually no filamnet extruded at all. PolFlex is highly flexible and when priming the filament is compressed and I suspect this comperssion is what makes the first layer successfull, when the pressure is gone, the feed is to slow to maintain the pressure.


While printing I adjusted:

Temperature to 233 °C

Material flow: 130 %

Print speed 150 %


Now it seems to flow again but I have no idea if these settings are good to go with or how to adjust the material profile to match my adjustments. I guess a lower material density would increas the flow?
