Top of Print Melting


Recommended Posts

Posted · Top of Print Melting

I have recently experienced trouble with the very end of my prints. Once the print head is finishing up the very top of my prints, it seems to melt the material and print out a glob. Is there a way to allow the material to set first before it smudges it around and messes up the very end?

Thanks for the help in advance!

    This is a problem with small tips or pointy bit.

    There are a few ways you can try to eliminate this.

    Its all due to not enough cooling.

    The best way is to print a small tower beside you object so that it allows time for it to cool before putting the next layer down.

    If the item is small you can print 2 or more at once.

    There is cool head lift that you can try. In my experience its not as good and can leave blobs on the side of your print from oozing.

    There is a minimum layer time that you can play around with. It slows the print speed down when the layer is small, this help prevent hot plastic being put down on top of a layer that hasn't had enough cooling. The problem with this is because its moving slow, the hot nozzle is still touching the plastic which tends to melt it anyway.
