Cura cutting off top portion of a round shaft part?

Post by CismontGuy »

Hello Forum,

I have a small shaft I want to try printing on its side on a raft over printing vertically. When I load the STL and try to set
the parameters in Cura the top portion of the shaft is being left flat? Like it was cut off. I am using a fine layer height
and have played with the infill and layers but cannot get the top portion to print?

Please see picture attached. I can attach a file if that would help? Thanks, CismontGuy

What's the layer resolution?
Also, why not vertically?

Hello Forum, My line width was too large for the part. I changed it to a smaller value and the part is now complete. No idea yet whether it will print OK. Starting the print right now. To answer the question, I want the print lines to run vertically, not circumference wise for the model CismontGuy

Okay, I get that for strength (z axis is the weakest)

Another idea you could try is with supports, doing it at 45 degrees?

So I have repeatedly tried to print this small shaft in a horizontal position. I have tried printing it vertically but they are worst. Even with a tower the whole height. I made the shaft diameter larger with the hopes of it working better but I still cannot get any support UNDERNEATH the shaft, at what I would call the 6 o'clock position. So... these lines of filament have nothing to stick to and the whole part is compromised. Any suggestions?

What layer height are you using to print shaft. I would use 0.12mm it takes longer though will give you a stronger shaft.

Yes.Thanks for the suggestion. I am using 0.12 right now with a 0.30 nozzel . I think Cura and my SV03 printer are not real good a fine detail? I am going to try printing 1/2 of the shaft, length wise along the equator and see whether, by starting with a flat surface it will even print? I also redrew the part in SolidWorks with my own darn supports as part of the model! We will see if that works or not? CismontGuy

Attach the STL shaft I will print it to see if Prusa slicer does a better job.
