Hello everyone, I am not an absolute 3D printing and slicer expert, but an advanced amateur, I think (and hope). :-D.
I’m trying to print this very long screw for the second time. Unfortunately, the print starts to fizzle out completely at a print progress of about 60 percent. (see picture)
I am at a loss as to what could be causing this. Of course, the nozzle temperature has not suddenly changed and has remained constant at around 230 degrees throughout the entire print. I print with eSUN PETG filament.
Does anyone have any idea what could be causing this? What data should I provide so that troubleshooting can be simplified?
Those screws are so long, they’re probably starting to vibrate while printing, because its a bedslinger. I would try to print them very slowly or lying down.
That really sounds very sensible and understandable. Thank you for this thought. I have already thought about printing the screws horizontally for other reasons. However, I see the problem that I am absolutely dependent on the round screw head and cannot flatten it, for example.
One way of not changing the shape of the screw would certainly be to print it horizontally with supports. However, I don’t have a separate support filament and am therefore worried that the supports will lead to improper pressure on the thread. Is this concern unjustified?
I would separate them a bit and then with the idea to have a support column in the middle up to ~120mm and hit the underside of a thread on each screw with the manual support painting, I would paint a few mm of support on there. Actually I would probably paint one at around 50mm then another one at around 120mm.
So then a tree grows up the middle then supports in a few small places the thread making it so the nozzle wont move the screw around. Also I would slow outer wall and maybe inner wall down a good bit so the layer time is increased.
Of course you could do that with a modifier on only the top section if the time increase is bothering you.
