Printed material moving about and lots of stringing


Recommended Posts

Posted (edited) · Printed material moving about and lots of stringing

Hello,

 

I've been experiencing printing failures with a lot of hairy stuff. It's probably what's called "stringing".

The printing went well up until some point, and then the shape started to show some problems and the severe stringing started. Once I confirmed that the nozzle was extruding the string into the midair while the half-printed material was off the spot and moving about. Not sure if this explains all the issues, but it appears that the bottom of the printed material was not stuck well enough.

 

I chose Build Plate Adhesion Type to be "Brim".

I cleaned the surface of the floor.

The material was PLA. Print core AA 0.4. Extra Fine 0.06 mm.

 

What else should I consider to prevent this?

 

Best,

Kouichi

Actually, this is related to the issue:

This is one example of the incident.

 

As shown in the pictures, when the print core reached a certain height (~27 mm), the "raft" went off the ground (the raft was not flat anymore) and the printed material started dancing on the floor with fluffy hair (stringing).
