Black Nylon Underextrusion Problem

Recommended Posts

Posted · Black Nylon Underextrusion Problem

Hello all

 

I want to print using Ultimaker 3 extended Nylon. I followed the recommended settings for printing and bed temperature (260 C and 60 C) but the printer does not print in contineous lines, it prints like small dots (underextrusion?) see attached picture. 

Can anyone help me out with this?

Could be a clogged nozzle. Try to make some hot/cold pulls or if you want to do a quick check, use another AA print core.

And most important with nylon, keep your spool dry! If you leave the spool outside of an airtight container for more than a few hours, the material absorbs too much moisture and you get serious extrusion problems. 

 

So your spool is probably already wet - but you can dry it again in an oven for several hours. Check the forum for temperatures.
