Patient-specific molds were generated by subtracting a patient’s 3D breast model from an enclosing volume (a). Internal structures, such as fibroglandular tissue and masses, were held in place with custom fixtures designed onto the mold (a). The mold, internal structures and fixtures were 3D printed using polylactic acid (PLA), a common and inexpensive 3D printing material (a). Silicone was poured into the 3D printed mold (b). Upon setting, fixtures holding internal structures were removed prior to releasing the mold. The cast was removed from the mold by gently separating the edges and tapping on the bottom of the mold (b)
