Lately I've noticed a trend of papers being published about generating 3D models using artificial intelligence. I think it's really amazing!
I don't really have the programming skills to get the AI running on my computer, but I did pull the example models from Google's Dreamfusion project and clean them up for 3D printing purposes.
All of the models should have a flat surface to set on the build plate, except the frog. I couldn't quite get a clean plane cut on that one, so one of the legs will need a little support.
You can check out Google's Dreamfusion project here: https://dreamfusion3d.github.io/
There's an open source project that works similarly here: https://github.com/ashawkey/stable-dreamfusion
Nvidia is doing something similar here: https://blogs.nvidia.com/blog/2022/09/23/3d-generative-ai-research-virtual-worlds/
