<p>I'm getting zits or blobs in lithophanes while printing on my Ender 3 and 10S Pro. I tried a suggestion: change resolution in mesh fixes of Cura to 0.5 (from 0.05 default). That removed the zits.</p>
<p>But now there are white patches as shown in the image. I reduced the resolution to 0.2 but to no avail.</p>
<p>Anyone else encountered this problem?</p>

It is sufficient for making a 3D model, but not in the way you want. Basically, you cannot turn a 2D image into a 3D model automatically, so you will have to do it manually. The image you have can be used as a reference image, and you will have to use some artistic freedom when creating the backside. It is basically the digital version of creating a clay sculpture based on an image. Perfectly possible, but it does require quite a bit of skill and patience.</p>\n<p>If you want to learn how to do it, search for beginner tutorials on YouTube about ‘sculpting’ in Blender.</p>\n'}, {'answer_id': 17981, 'author': 'Dave', 'author_id': 30919, 'author_profile': 'https://3dprinting.stackexchange.com/users/30919', 'pm_score': 0, 'selected': False, 'text': "<p>If you only have a 2D photo then as others have already said its not really possible.  However if you have the action figure itself you could try a technique called Photogrammetry where you use your phone to take multiple images of the object and then use software to build up a model. Search youtube for guides on Photogrammetry or 3D scanning with your phone. I've never done it but certainly something I'd like to try!</p>\n"}]
