<p>I have designed a bread mark and printed it on the Prusa i3 MK3.</p>

<p><a href="https://i.stack.imgur.com/qs5PP.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/qs5PP.png" alt="Bread mark"></a></p>

<p>I wanted it to have as sharp edges as possible, so I used a triangle:</p>

<p><a href="https://i.stack.imgur.com/AMTCP.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/AMTCP.png" alt="Triangle"></a></p>

<p>However, it seems that the print cut off layers that are too thin (x-y-wise) and instead of a 1 cm high bread mark, I only have 0.5 cm.</p>

<p>What is the X-Y-resolution of the Prusa i3 MK3? In Slic3r, can I make sure that any wall is made as thick as needed for it to be printed?</p>

<p>I have the default 0.4 mm nozzle.</p>

So for a standard 0.4 mm nozzle, the model will be cut in a way that keeps at <em>least</em> 0.4 mm thick walls, or, if the slicer is extra careful, double that, as the model demands 2 walls next to each other. The result is, that the model with such sharp walls will be cut till the model does conform to the minimum wall thickness - in your case about half the height of the model. </p>\n\n<p>I strongly encourage to further read <a href="https://3dprinting.stackexchange.com/a/6830/8884">What special considerations must be taken when designing parts for 3D printing?</a></p>\n'}]
