Vectric, whose software for CNC is widely used to create and machine 2D and 3D carvings just released an AI based tool call
Easy Create for creating 3D models that can be carved on a CNC. I think that you can save them as an STL so you could also 3D print them. You buy 200 credits for $20 and I think that cost comes out to about about 50 cents per ready to carve model. You describe what you want and it comes up with a model. You can similarly provide a photo and it will create a 3D model you can carve on the CNC. You can give it instructions such as removing background or making parts of it less detailed. I have not tried it yet but some of the examples I have seen are pretty impressive. it does a pretty good job of handling faces as long as there are not too many faces in the photo you give it to convert. If you have more than about 5 or 6 faces, everyone starts looking like aliens wearing human masks. The more faces, the worse it gets. I sure that they will improve that as time goes on.
