fraying and stopping of the print


Recommended Posts

Posted · fraying and stopping of the print

Hi everyone, 

 

I have a problem with the printing of PP: at some point during the printing, the material inflow or something stops, resulting in frayed endings. This sometimes happens at the beginning of a print (see picture 1 and 2) or when the print is more at the end (picture 3). I have tried to solve this by changing the printing temperature, the printing speed, and the layer height, but it doesn't work. 

 

Does anyone know some more actions I can try? 

 

Thanks in advance!

    Hi @Stefanbos, welcome to our community! 
    Let's see if we can help ?

     

    Could you first see if your front fan is still working? It can be something as simple as a small string of filament preventing the blades from spinning. When it can not cool properly, heat can travel up through the filament and make it soft higher up in the extrusion train, where it continuously receives pressure from more material which is being fed in. So it expands, and at some point can't be pushed down any further. Good luck!
