<p>I recently got started in 3D printing but here's an issue I can't seem to find a solution for (I don't know what exactly to look for).</p>

<p>Here's what I did:</p>

<ul>
<li>I used InkScape to convert an emoji in to a svg and imported it in to Blender</li>
<li>Used the Solidify modifier to make the curve a solid and converted it in to a mesh</li>
<li>Extruded the mesh a bit, fixed a few non-manifold vertices and erroneous faces and saved the whole shebang as STL</li>
<li>Imported the STL in to my printers software:

<li>After slicing it looks like this:

</ul>

<p>Is the software making a mistake during the slicing? Or is my mesh screwed up?</p>

<p>I have a FlashForge Finder and using the software that came with it: FlashPrint.</p>

<p>Edit: I uploaded everything to <a href="https://www.thingiverse.com/thing:2616300" rel="nofollow noreferrer">Thingiverse</a> for those who are interested.</p>

It\'s a problem in the slicer software.</p>\n\n<p>Because your 3D printer prints with a (for example) 0.4mm nozzle, it lays down lines of plastic that are around (for example) 0.5mm wide. The slicer has to create a pattern, consisting of 0.5mm wide lines, that fills in your object. The gaps shown in your object are likely smaller than this, and thus can\'t be filled.</p>\n\n<p>I am not familiar with the flashforge software, but different slicers have different ways of dealing with this. Some offer a "gap fill" option that uses tricks to be able to fill in these very tiny gaps by rapidly moving the extruder back and forth over the gap. However, even then, it is sometimes unavoidable that tiny gaps remain. Some gaps are just too small to fill with the comparatively large nozzle.</p>\n'}, {'answer_id': 4840, 'author': 'darth pixel', 'author_id': 1211, 'author_profile': 'https://3dprinting.stackexchange.com/users/1211', 'pm_score': 4, 'selected': True, 'text': '<p>here is just a addenum to Tom van der Zanden\'s answer</p>\n\n<p>this is (an example of) what you may design - nice object with virtual outline, and virtual fill\nso this is what you see (and what you potentially expect)</p>\n\n<p><a href="https://i.stack.imgur.com/61gRm.png" rel="noreferrer"><img src="https://i.stack.imgur.com/61gRm.png" alt="enter image description here"></a></p>\n\n<p>but here is what you get (and probably not really expect)</p>\n\n<p><a href="https://i.stack.imgur.com/5HdqS.png" rel="noreferrer"><img src="https://i.stack.imgur.com/5HdqS.png" alt="enter image description here"></a></p>\n\n<p>red parts are the areas which are not covered by fill because nozzle cannot reach there</p>\n\n<p>solution is </p>\n\n<ul>\n<li>to redesign your object in smart way or</li>\n<li>to use smaller nozzle or</li>\n<li>to use smarter app (like <a href="http://slic3r.org/" rel="noreferrer">Slic3r</a>)</li>\n</ul>\n\n<p>and of course you can use all 3 options together to get best results ;)</p>\n\n<p><strong>EDIT</strong>\nhere is simple explanation why smarter app could do the thing\n<a href="https://i.stack.imgur.com/VBrLW.png" rel="noreferrer"><img src="https://i.stack.imgur.com/VBrLW.png" alt="enter image description here"></a></p>\n\n<p>and here goes the difference</p>\n\n<p><a href="https://i.stack.imgur.com/3nNEN.png" rel="noreferrer"><img src="https://i.stack.imgur.com/3nNEN.png" alt="enter image description here"></a></p>\n\n<p>green parts are new covered areas</p>\n\n<p>not much but somthing extra</p>\n'}]
