Was hoping someone could help with this issue I’ve been having.
I print mostly in HIPS, but also on occasion in PLA, and this problem happens with both filament types (to a lesser extent on PLA). HIPS is the worst offender for me.
What happens is the part starts to distort as the edges pull away from the bed. This has been happening with my printer ever since I got it. For the most part I haven’t printed anything that’s taken a REALLY long time to print so it hasn’t bothered me much. What I do notice is that the retraction is more pronounced the thicker the part is. If for example I printed a triangular part, the thicker part would retract more than the thinner end.
Here are some pictures of the most recent failure…
As you can see the part sitting on the print bed, the corners have lifted and distorted. The bottom shot shows how warped the edge is as a result of the part pulling away from the bed.
In this case printing eSun HIPS black, the hot end temperature was set to 240 degrees and the heated bed at 110. If I keep it any less than 110 the part won’t stay on the bed at all. I am thinking that it’s heat related. The PEI film is brand new, and was cleaned before the print was done.
I am guessing that the solution would be to get the part to stick better to the bed and use less heat… but how would that be accomplished. Sure I can turn the heat down, but then what’s the point of the heat as it doesn’t do anything to keep the part stuck to the bed while printing.
This is me stumped!!!
Any help or comments would be very much appreciated.
