  • Publication number: 20230302734
    Abstract: A three dimensional (3D) printing apparatus to print an implantable bone scaffold (IBS) in an aseptic environment is described. The 3D printing apparatus includes a sterile cartridge. The sterile cartridge contains a sterile printing material, a print nozzle, and a plunger. The 3D printing apparatus also includes a heater configured to indirectly heat the printing material. In addition, the 3D printing apparatus includes a cartridge receiver configured to retain the sterile cartridge. A sterile receiving plate is positioned below the print nozzle. A cover encompasses and maintains the sterile cartridge and the sterile receiving plate in an aseptic environment. A filter fan unit (FFU) overlays a section of the cover. Positive laminar filtered air flow created by the FFU maintains the aseptic environment inside a printing chamber. An ultraviolet light source irradiates the receiving plate. A movable diaphragm separates a printer mechanism, below the receiving plate, from the printing chamber.

  • Patent number: 11556682
    Abstract: A method for producing bone grafts using 3-D printing is employed using a 3-D image of a graft location to produce a 3-D model of the graft. This is printed using a 3-D printer and a printing medium that produces a porous, biocompatible, biodegradable material that is conducive to osteoinduction. For example, the printing medium may be PCL, PLLA, PGLA, or another approved biocompatible polymer. In addition such a method may be useful for cosmetic surgeries, reconstructive surgeries, and various techniques required by such procedures. Once the graft is placed, natural bone gradually replaces the graft.

  • Publication number: 20150054195
    Abstract: A method for producing bone grafts using 3-D printing is employed using a 3-D image of a graft location to produce a 3-D model of the graft. This is printed using a 3-D printer and an ink that produces a porous, biocompatible, biodegradable material that is conducive to osteoinduction. This is porous poly methyl methacrylate (PMMA) made osteoinductive by demineralized bone (DMB). The ink is provided as a precursor powder and liquid. The powder contains DMB, sucrose crystals and a polymerization initiator. The liquid contains methyl methacrylate (MMA). Optional compounds include antibiotics, radio-pacifiers, and compounds to increase biodegradability. Once mixed, the MMA polymerizes to PMMA. The ingredients are proportioned so that the ink is delivered through a 10 gauge print nozzle for about 10 minutes per batch. Once the graft is placed, natural bone gradually replaces the graft.
