PAHT CF 15

[sina-ghy 0]

Hi guys 

 

Does anyone knows that if it is possible to print with PAHT CF 15 filament on Ultimkaer 3. I have normal brass nozzles. I also tried to add the filament profile to Cura, but it doesn't accept it. If I define a custom material, can I print with that? Any thoughts? Thanks a lot.

You will quickly wear out your printcore, but worse is that also your feeder wheel will wear out, which will harm the performance for all materials.

For printing abrasive (filled) materials, you have to upgrade to an S3 or S5. These have hardened feeder wheels out of the box, and you’ll have to purchase a CC print core with a ruby nozzle.

The warning on the quick demise of brass print cores and feeders should be heeded. 

 

I bought a used UM3 that had  (i understood) about half a kilo of Nylon/CF through it.  Print core and #1 feeder heavily worn.  AA 0.4 was already at 0.6 and visibly shorter and flatter tipped than spec.  The feeder was already worn to the point of slipping and mishandling retractions.

 

There is a solution though.  Both of my UM3's now run Bondtech feeders (hardened and replaceable drive gears) and I use 3dSolex hardcores when printing abrasive stuff.  Not a cheap upgrade but way less than an entirely new printer.  I have been running this configuration for 18 months and no visible degradation.

 

Hope this helps!

Hi John 

 

Thanks for your message. That was really helpful and I'm happy that I didn't run this filament before changing the feeder and the core 🙂 . The pricing looks promising though compared with buying a new printer. Many thanks for you response. 

 

Cheers,

Hi John 

 

Can you please share an image of you current setup so I can have better idea?

Hi Sina.  I'm running some jobs with regular materials and print cores for the next while so won't have much chance to get photos.

 

The good news is that the changes I made (which I learned about here, there are a number of related threads)  are very much off the shelf.  Bondtech and 3D Solex have resellers in many places.  I went with the Bondtech DDG, which is a straight swap for the UM3 extruders.  10 minute job.  The hardcores can be ordered with an everlast nozzle already installed.

 

Where are you located?
