Printing Polycarbonate with 0.25mm nozzle

Recommended Posts

Hi,

We have been trying to challenge the best resolution with Polycarbonate.

So far, using the 0.4mm nozzle and increasing the resolution through changing the layer height to 0.08 has been successful, however, it shouldn't be the best the machine can do.

It seems like Cura allows for the use of 0.25mm nozzle, however, our experience has been that the material gets stuck in the tip soon after just a few seconds of extrusion. We have cleaned the tip with acetone in order to unblock the tip, however, it gets blocked again right away.

Is there possible adjustments we can do in the setting (ie. temperature) that would rescue the situation and make it possible to print PC with 0.25mm nozzle?

Thank you in advance for any advice!

Ying

You're probably dealing with material being heated to the point of flowing for too long. The PC gets to the nozzle and sits there melted for a while waiting to get pushed through the tiny hole. This could be a good reason for changing to 1.75 mm filament, but of course hardware changes are necessary for that and it would not be a guaranteed fix. Would it be worth the time and dollars required to tinker for a possible improvement of print quality
