PP no longer printing

[Tiger91 1]

Hello,

 

I tried printing with a spool of PP recently on a UM3, current cura version, and had no luck.  It turned to silly string.  I tried changing the temperature, flow, speed, etc but no success.  The first layer adheres well, but it seems as though it just doesn't extrude enough after layer 1.  There is no clog however, and other materials work fine.

 

Any suggestions?  That stupid spool is $70 down the toilet otherwise.

 

Thanks,

 

Tiger

Does nobody print with PP?

I think maybe nobody responded because your description of the problem is quite vague.  You could provide additional info such as add pictures, describe the problem in more detail, mention what may have changed between when it was working and when it was no longer working, etc.

Verbatim polypropylene is less expensive and prints identically to the Ultimaker brand, I am actually curious if they are just rebranding it.  Matterhackers has PP spools for $50.  They also have Natural SmartMaterials SmartFil PP which I have tried and it is much different.  It is more brittle, a different texture, and does not stick to the glass bed.  I would not recommend that brand.
