How to prevent layer separation, when printing tall vase-like (tube) objects?
I am experiencing a minor layer separation when printing a body for a tipping-bucket rain gauge, which is basically a hollow tube with thin walls (3 mm). I am using Prusa I3 MK2 and a Fillamentum ABS white plastic. The model has been sliced in Siplify 3D with the following settings:
- layer height: 0.2 mm
- perimeter shells: 3 layers (almost entirely
fills up the wall) - extruder temperature: 230 °C
- printing speed: default - 50 mm/s, outline - 35 mm/s, infill - 35 mm/s
Is it possible to prevent the irregular and layer separation by adjusting some of the settings, and not significantly increasing the printing time, which is already 13 hours?
PICTURES:
such a large print needs a heated chamber.
Yes, it needs to be printed from ABS due to its better UV resistance. @Toonils it seems to be the problem. Thank you, I will try to create the chamber.
If the level of detail you need is not too fine, perhaps using a larger nozzle - should make for faster printing and will reduce odds of clogs/partial clogs and should improve layer adhesion (more hot plastic sticks better than less hot plastic.)

Do you need to use ABS, or could you try PLA, which is easier to deal with and might meet your operational environment needs?
