<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>

These options should improve the quality of the print as they improve the layer adhesion, however none of these options will completely solve the problem.</p>\n\n<p>alternatively you can repair the current print. In order to do this you will need to use something cot such as a soldering iron with a variable temperature, to melt and rejoined the layers. similarly you can use a 3d pen to apply additional plastic across the sections of separation in order to repair it.</p>\n'}]
