Hello , I am new here and I am looking for some direction and I will explain.
I want to make a negative mold of a photo from a computer and it will be about 3 inches in diameter. An example of what I want to use these molds for would be say clay forming. I want to be able to pres the clay into the mold to copy the picture in clay. I want to be able to do this by having a person send me a picture on the internet and then be able to download it to a laser or milling machine and then be able to cut the picture in aluminum to form the mold. These molds are all different as all the pictures will be different.

I am thinking of a table top cnc laser, I had asked a person if this could be done with a cnc milling machine and he suggested a laser.

Does anyone know how to accomplish this, I have to be careful as I dont want this to be cost prohibitive. I understand that the machine will be a cost.

Thank you
Schllac
