Can any machine do all the engraving ie taking a photo of person and 2d to 3d then engrave it in any item they want?
[I've never heard of a machine like that. Usually you have to get a separate scanner, or at least a camera. Then you have to process the image for the machine before it will engrave or produce the sub-surface dots.]
I don't see 3d heart shape like this
