*Heads-up: I’m Jan, one of the people behind 3D AI Studio. This post is* ***not*** *a sales pitch. Everything shown below can be replicated with free, open-source software; I’ve listed those alternatives in the first comment so no one feels locked into our tool.* Sketched a one-wheel robot on my iPad over coffee -> dumped the PNG into Image Studio in 3DAIStudio (Alternative here is ChatGPT or Gemini, any model that can do image to image, see workflow below) [](https://preview.redd.it/ai-is-getting-insane-generating-3d-models-with-open-source-v0-xta4k93kqx2f1.png?width=2290&format=png&auto=webp&s=46fa614a304ee658b3c2235b6ce2b40072484bf0) [Sketch to Image in 3daistudio](https://preview.redd.it/ahf4q4dwhy2f1.png?width=2290&format=png&auto=webp&s=657e23cce1fec01e4f6b169bcd6795d808fd410a) Using the Prompt *"Transform the provided sketch into a finished image that matches the user’s description. Preserve the original composition, aspect-ratio, perspective and key line-work unless the user requests changes. Apply colours, textures, lighting and stylistic details according to the user prompt. The user says:, stylizzed 3d rendering of a robot on weels, pixar, disney style"* **Instead of doing this on the website you can use ChatGPT and just upload your sketch with the same prompt!** Clicked “Load into Image to 3D” with the default Prism 1.5 setting. *(Free alternative here is Open Source 3D AI Models like Trellis but this is just a bit easier)* [](https://preview.redd.it/ai-is-getting-insane-generating-3d-models-with-open-source-v0-1btcahrlqx2f1.png?width=2283&format=png&auto=webp&s=8329e1cb6a957a00cfeef3f27ce98b40cda85d56) \~ 40 seconds later I get a mesh, remeshed to 7k tris inside the same UI, exported STL, sliced in Bambu Studio, and the print finished in just under three hours.

(ChatGPT is the easiest option tho as most people will have it already). ChatGPT gives you roughly the same: [Using ChatGPT to generate an Image from Sketch](https://preview.redd.it/8vhy6i9iiy2f1.png?width=913&format=png&auto=webp&s=0d131a8c241afde688fe13531dfa8a301e08c421) Image-to-3D works with the open models Hunyuan3D-2 or TRELLIS; both run on a local GPU or on Google Colab’s free tier.
