I wants to do a 3d models Richie an Eddie out of bottom but Richie's dead can I do it from a picture

There are AI models which can generate 3D models but the fidelity of the models aren't good enough for 3D printing. They make it look good on a computer screen with a texture and smooth shading, but 3D printers don't print the texture and real life objects don't have smooth shading like models in a computer do.
