How to print single wall hollow cylinders


Recommended Posts

Posted · How to print single wall hollow cylinders

Hello

 

I'm trying to print these two cylinders. I realized that for some reason the nozzle always passes 2 times over each circle ( the red ones on the screenshot below).

the cylinders are hollow and have a 1mm thickness.

I am using a 1mm nozzle and I specified the wall width of 1mm.

Because of this 2nd pass, the PLA doesn't have time to cool down and it results in a failed print.

 

How do I force CURA to pass only 1 time per circle?

    There is a spiralize mode,  if you are willing to print the two separately? Otherwise I will leave this to the experts 😅

    • Make sure "Ironing" is turned off.
    • Increase the the "Line Width" to 1.05 or 1.1.
    • Print a second pair so the layer time is stretched out.
    • Increase Minimum Layer Time.  This will slow down the print head.
    • Make sure the cooling fan is running at 100%.  You are pushing a lot of material and it has some thermal inertia and doesn't cool as fast as it would with a smaller nozzle.

    You might want to play with "Lift Head".  I haven't used it but I believe that cases like this are what it's for.  Could be stringy though since it's a glorified Zhop.
