I’ve printed similar objects with a different colored PLA, but I ran out of it and switched to this.
Is it possible that this could be influencing the outcome?
I have tried reducing the printing speed by 50%, but this did not seem to have a significant impact.
Isn’t this kind of a torture case for 3D printing? The higher you go, the more the part itself is an unreliable surface. Even in subtractive manufacturing, any weird sticky-outy bit with an extreme aspect ratio is prone to getting snipped off to become a separate piece.
Print two cylinders half this tall. Or print one piece flat along the board. Or buy a plastic dowel.
Check if your print is wobbling when it reaches that height. If it does, you may need to add support to fix that - a few organic support touch points halfway up should help
Could you give me advice on how to do that? Is it something that I would have to add manually in a 3D modeling program, or is there a way to do it in Cura?
I am not too familiar with Cura, but I don’t think they have the ‘support painting’ feature of prusaslicer and the likes that would allow this. In those, you can paint where you’d like your support to touch or use modifier meshes to selectively add regions that should be supported. It’s the easiest way I know, though I have heard that Meshmixer also used to be able to do that… but I’ve never tried.
Z binding, I think. Your Z axis is binding up either due to issues with that area of your screws or overheating of the motors (less likely). Lubrication can help unless there is an issue of the screws being warped.
Edit: what machine are you using?
Thank you for this information. I am using a Creality Ender 3 V2.
So, this seems counterintuitive, but slightly loosening the part that attaches to the x axis can help as well.
For clarity, you loosen the brass fitting on the x axis that attaches the rod to the x axis.
In machining/cnc land everything is a spring. I would suggest finding a way to print it with a more rigid setup. Maybe try putting some kind of support around the cylinder part way up.
It’s a cylinder I swear!
Print again same gcode. If the rings are at the same height its Z axis issue, otherwise model is just too tall
New thought: set the stl up, drop it through the floor of the build plate to only print the stupid area. That narrows it down to wobble or z binding. Z hop could help a bit with wobble.
Hate to tell you but 3d printing Is not the right manufacturing process for the job … You may have It work out but thers no reason to melt pellet plastic into a somehow precise 1.7 mm diameter wire spool so that you can make a noozle go round for hours… Just buy a pipe … No matter what it will be cheaper more precise and sturdier …
I’ve been able to print similar models before with a different PLA and no issue.
