Innofil InnoFlex 45 - Ultimaker 2+ problem

[Camfrla 0]

Hello,

I am trying to print InnoFlex 45 on UM2+ for few days. Unfornutally i don't have any satisfying results. I already tried general suggestion for printing flexible material. Is there any person who had succesfully printed with this flexible material? What settings did you used? I know that flexible material is not good for bowden tube, but maybe someone has more luck then me.

Thank you all for your responds

Have you tried putting a few drops of oil in the bowden tube or using a oiler on the filament?

you also need to print really slow like 10mm/s

Hi Camfria,

I'm not certain on the design of the Ultimaker 2 extruder drive, but many people find issues with flexible filaments in extruder drives that don't have a fully contrained path between the drive gear and the nozzle. If there are any gaps, the flexible filament can fold up in the space and doesn't reach the nozzle. See the guide here http://www.gyrobot.co.uk/blog/how-to-3d-print-with-flexible-filaments

In may cases, you can find a model to print a different casing for your extruder drive on one of the 3D print file sharing websites like thingiverse or pinshape.
