<p>increasing the temperature by 5 to 10° as well as, increasing the layer thickness to "0.3" or "0.35" may assist ,additionally increasing the flow rate of the filament, by a small margin at most 10%.

<p>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 <strong>Prusa I3 MK2</strong> and a <strong>Fillamentum ABS</strong> white plastic. The model has been sliced in <strong>Siplify 3D</strong> with the following settings:</p>

<ul>
<li>layer height: 0.2 mm</li>
<li>perimeter shells: 3 layers (almost entirely
fills up the wall)</li>
<li>extruder temperature: 230 °C</li>
<li>printing speed: default - 50 mm/s, outline - 35 mm/s, infill - 35 mm/s</li>
</ul>

<p>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?</p>

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

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.)

How to prevent layer separation, when printing tall vase-like (tube) objects?

# How to prevent layer separation, when printing tall vase-like (tube) objects?

(Asked by: username_0 on 2017-08-15)

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?
