Support material temperature question


Recommended Posts

Posted · Support material temperature question

Hi all,

 

Our support material roll has been opened for a while and our prints don't use that much of it. What I have noticed recently, and I'm not sure if this can be fixed by changing the temperature or if it's just caused by the material to be too old, but it appears that when the support filament is being applied to my print, when the head moves to change position to go apply support somewhere else which is not a contiguous location of where it was printing, rather than cleanly breaking away, it seems to stretch the filament and it becomes really small, like the diameter of a hair. Then what happens is that quite often, this stretched piece of filament will overlap the PLA material where it last printed and then when the printer goes to switch the head back to PLA, when the PLA filament gets applied to the location where the support filament overlapped the PLA, the PLA will print over this fine piece of support. Then as the PLA gets printed over time, there will be many of thes support filament across many PLA layers and when the print is finished and I put the print in a ultrasonic bath to remove the support, everywhere where there was 'accidental' support filaments between PLA layers will cause a gap.... or in other words, the face will be covered with pits. Not sure if this is clear or not. I attached a picture of what I mean. All the white lines and the evident gaps were caused by this support filament overlapping PLA layers.

 

How can I fix this?

 

Printer is S5.

 

Thanks.
