PAHT CF15: Tips and Tricks

In this article you will find some information that will help you to master the PAHT CF15






Note: This article contains advanced information regarding BCN3D PAHT CF15. The default settings for our BCN3D PAHT CF15 have been tailored for good quality and reliable results, and are fully tested by our laboratory. These tips complement those settings to ensure the best quality in printing with PAHT CF15.


PAHT CF15 (High-Temperature Polyamide reinforced with Carbon Fiber) is a composite filament that is stronger and stiffer than regular PA, it can withstand high operative temperatures, and it is very resistant to bending and shear forces. This makes this filament suitable to print end-use parts that work under high stress. 


This filament is quite easy to print and behaves quite well, however, there are some tips that will help you refine your results.  


Tip: Check out this material compatibility chart, it will help you choose the materials that fit best with PAHT CF15:

Supported Material Combinations.


Store it well

PAHT is hygroscopic, which means it absorbs moisture from the environment and does it quickly. When this happens, the PAHT polymeric chains break down as the material heats up, making it runnier. This can cause stringing and various printing quality issues related to the part's strength. 

If you want to prevent this from happening and know a bit more about this phenomenon, check out our guide on how to solve this common issue:

An abrasive one


PAHT CF15 has Carbon Fiber in it, and it is quite abrasive. It is recommended to print it with our Hotend X, otherwise, it will wear out the regular hotends making them unusable in no time.

Make it stick

PAHT doesn't need any special considerations regarding adhesion, you can simply print it with a clean build plate or with regular Magigoo with no warping, as long as the printing surface is well calibrated. 

Postprocessing PAHT CF15



If you need to post-process your print, like removing blobs or strings, you can use a scalpel to remove them, they'll come out easily. If you intend to sand down or polish your PAHT CF15 part for some reason, you should use safety glasses and an FFP3 facemask to prevent particles of this material from entering your eyes and lungs.
