<p>I have been working hard the last year on the model below. I am new to everything 3D that is modeling and especially 3D printing. I have however successfully concluded quite a good number of 3D prints which I created in blender with my Creality Ender 3 Pro so I have a bit of experience.</p>

<p>All this new experience for me started with the desire to do this project I have been working on for all this year. A complex 3D model of a knight's tomb which I would like to print.</p>

<p>As you can see Cura is clearly indicating that there is a need for supports in these red areas. The model will be printed in a 15&nbsp;cm size. I have also managed to resize the model from a 22 million face mesh full of holes to a 900k manifold model.</p>

<p>However, when I slice it I get this.</p>

<p>As you can see supports are only generated for the outer column part. None are generated for the arches which are totally absent when the model is sliced.</p>

<p>I have tried to alter the model's orientation but with no result. I will try to separate this mesh in parts but it would mean restarting all from scratch since I found no good software to slice it precisely.</p>

<p>I am quite sure that the main problem lies in the fact the Ender 3 pro is an FDM printer an that the vertical lines of the arches are too thin.   Since I tried to upload my model on 3D printing services to see if it could be printed in other materials and could be printed in finely detailed resin.  </p>

<p>I would like at least to know if I am right in my problem spotting or if there could be any solution to the present problem so that not to go wrong if I will redesign this part.</p>
