<p>I have a set of 2D pictures from a CT scan.</p>

<p>How can I convert them into a 3D model for 3D printing? An example looks like this:</p>

<p><a href="https://i.stack.imgur.com/EV9Q8.jpg" rel="nofollow noreferrer" title="CT-Scan of a mouse&#39;s bones"><img src="https://i.stack.imgur.com/EV9Q8.jpg" alt="CT-Scan of a mouse&#39;s bones" title="CT-Scan of a mouse&#39;s bones"></a></p>
