Topic: Parts lifting
So I'm admittedly a newbie here. I've got a few fun prints under my belt but have already noticed that larger parts, particularly those that I'd call "elongated" (long but thin in X/Y dimensions) that they start to lift at the edges as the layers build. Eventually the extruder hits a lifted edge and pops the entire part off the bed.
This is obviously contraction of the material as it cools.
I have an enclosed SD4. I've let it run all day so I know the internal temp is as warm as it's going to get. This is 100% repeatable.
I don't believe any kind of adhesive on the bed is a solution, as that is addressing the symptoms, not the cause, so:
- is reducing extruder temp to the bare minimum for extrusion the answer?
- I've seen print cooling ducts, is forced-air cooling so the layer can cool on-the-fly (as opposed to the whole part) the answer?
Feedback please..
Thanks!
