System and method for making a breast prosthesis

A mould assembly for injection moulding a personalised hollow breast prosthesis, wherein the mould assembly comprises:

• a front mould being a female mould of a front side of a patients breast and comprising a first mould surface,
• a rear mould being a female mould of a patients mastectomized chest and comprising a second mould surface,
• a mould core comprising a mould core main body being a scaled positive mould of a combination of the patients breast and the patients mastectomized chest, wherein the mould core is smaller than the combination,
• a support configured to support the mould core main body in an assembled state of the mould assembly and to hold the mould core main body in a predetermined position relative to the front mould and rear mould,
• wherein an injection opening is defined by any of the front mould, the rear mould, and the mould core, and wherein in the assembled state the mould core is located between the front mould and the rear mould in order for a mould core surface to be located at a distance from the first mould surface and the second mould surface, wherein in the assembled state an inner volume is defined by the front mould, the rear mould and the mould core, wherein the inner volume extends around the mould core and is configured to be filled with an injection moulding material.
