The invention discloses a 3D printing-based anti-seep breast
prosthesis forming method and a breast
prosthesis, solving the technical problem of rupture or seep of the existing breast
prosthesis. The method comprises the following steps: acquiring
mammary gland image data; creating a 3D breast prosthesis
stent model based on the acquired
mammary gland image data; carrying out 3D printing by using a
hydrolysis material based on the 3D breast prosthesis
stent model so as to obtain a breast prosthesis
stent, wherein the breast prosthesis stent comprises a breast prosthesis stent body, and a glue injecting hole is formed in the breast prosthesis stent body; immersing the breast prosthesis stent in a
silicone rubber
sizing material for carrying out vulcanizing and crosslinking treatment, and hydrolyzing the breast prosthesis stent to obtain a breast prosthesis
silicone rubber envelope; injecting breast prosthesis filler into the breast prosthesis
silicone rubber envelope through the glue injecting hole; and vulcanizing and sealing the glue injecting hole so as to obtain the anti-seep breast prosthesis. The breast prosthesis obtained by the forming method does not have gaps, conforms to
human engineering mechanics, and can be ensured to be free from seep.
