<p>I'm still putting aside money for buying my first 3D printer and I'm designing all the things I have to print.  </p>

<p>As I have <strong>a lot of things</strong> to print I would like to print as much of them as possible in a single print.</p>

<p>I have some arcs of circle (between 90° and 320° and 10/30 cm of diameter) and I'm going to slice them so I'll be able to print many of them, vertically, in a single print. I read in the internet that I cannot print over 45°... but starting from where?</p>

<p>The image below shows how I would like to print my (orange) things</p>

<p>I suppose I can print my things without supports because from Y-start to Y-end they are &lt;= 45° (as the green line shows) is that right?</p>

<p>The red line, instead, shows a case where the angle, starting from a (Y: 50%) point, is higher than 45°.</p>

<p><strong>So the question is</strong>: Can I print my things in such way?</p>
