I'm not into 3D printing, so I'm unsure of what viable means in that context, but for photogrammetry in general, I've had success generating 3D models of little figurines/statues with just a bunch (~15-20) of photos from my cell phone using Meshroom[1] followed by light touch up in Blender[2] to separate the environment from the model. Both are open source.
