The invention relates to a method for the manufacture of a breast prosthesis, comprising: providing and superimposing inner and outer plastic foils; welding together the plastic foils to form the circumferential welding seam, thereby leaving a gap to form a filling channel connecting the inner space to an outside; filling the inner space with a fluid curable mass, which is a precursor of the filler material, by injecting the fluid curable mass into the inner space through the filling channel; and curing the fluid curable mass inside the inner space to form the filler material; wherein the filling channel is provided with a check valve to prevent fluid curable mass from entering the filling channel after injection. The invention additionally proposes a breast prosthesis made by such method.

Thermoplastic 3D objects are printed directly onto permeable materials with a high strength bond. The 3D object can be attached to the permeable material at one side where the bottom layer of the 3D object can be attached to the permeable material or alternatively, at an internal layer where portions of the 3D object are on opposite sides of the permeable material. In order to improve the adhesion of the 3D object to the permeable material, the bonding layer of the liquid thermoplastic material that is printed directly onto the permeable material can be deposited at modified 3D printer settings that can include a hotter than normal material deposition temperature. Additional build layers of the liquid thermoplastic material are printed on the bonding layer to complete the 3D objects.

wherein the manufacturing method comprises the following steps: providing a skin (1), making a plurality of through drill holes (6) on the skin (1) located in correspondence with areas where the placement of stiffeners (3, 4) is expected, introducing threaded bolts (5) in the through drill holes (6) such that the head (11) of the threaded bolt (5) remains housed in the skin (1), locating a threaded nut (10) on the free end of the threaded bolts (5), manufacturing the stiffeners (3, 4) such that the threaded bolts (5) and the threaded nut (10) remain embedded in the stiffeners (3, 4).

In certain embodiments, a system for making an implant for an eye comprises a printer, a camera, and a computer. The printer prints material onto a target and has a printer head and printer controller. The printer head deposits the material onto the target, and the printer controller moves the printer head to deposit the material onto a specific location of the target. The camera generates an image to monitor the printing of the material. The computer stores a pattern for the implant, which is designed to provide refractive treatment for the eye; sends instructions to the printer controller to move the printer head to print the material onto the target according to the pattern; assesses the image from the camera according to the pattern; and adjusts the instructions in response to the image.
