The present disclosure provides a method for producing a customised teat product for a subject, the method includes the initial step of performing a 3D scan of at least a nipple region of the subject's breast to create a 3D model of the nipple region. In the next step, a 3D product model for a teat product is created, incorporating a teat that corresponds in shape to at least the nipple region of the subject, based on the 3D model of the nipple region. In the final step, a physical teat product is generated based on the 3D product model using an additive or subtractive manufacturing apparatus.
