    yes it does - that's why you use pla or pet-g instead :-)

    It is difficult, but if you reduce your sharp corners as well as increase the amount of heat into your filiament it can be fixed.

    I find that sharp or sharper corners are normally where the cracks propagate from. There is a good reason for this called stress raisers if you want to research it. If you dial up your heat or dial down your speed and reduce sharp corners it will help a lot.

    The original thread was asking the question:
    “Has anyone ever used DAP kwik seal plus to fill in the gaps and cracks after an assembly of 3D parts. After gluing the 3D printed parts, there were some gaps and cracks. I used the kwik seal to fill in the cracks and gaps, then I used fine sandpaper to flush the kwik seal with the plastic parts. For the purpose of this project, the kwik seal worked great! It has filled in the gaps and cracks, and I like it...
    I like your response and I will explore the idea of dialing up the heat or down the speed to reduce sharp corners...But sometimes you need a sharp corner...oh well, it’s like a Möbius strip...oh well, in the end it gets figured out. Thank you

    I’ve never used pet-g. How do you like it? What have you used it for? Is it more expensive than pla or abs?
