What is How do I build a 2D image 3D model without expensive software?

You can create a 3D model from a 2D image without expensive software using free/low-cost photogrammetry, AI, or manual tools.

- **Photogrammetry**: Tools like Meshroom use multiple 2D photos to calculate depth and build models. - **AI**: Tools like Luma AI (free plan) or DreamFusion generate 3D from single images via machine learning. - **Manual**: Blender (free) lets you trace 2D shapes and extrude them into 3D objects.

For beginners, start with Luma AI—upload a clear 2D image for easy conversion. For more control, use Blender’s extrude feature to turn sketches into 3D.
