Abstract
A filament or printing material placed in a syringe for 3D printing comprising polymers, proteins, and/or functional particles and materials is provided. Methods of treating a bone defect in a subject in need thereof comprising using a handheld 3D printer to apply a filament or the printing material placed in a syringe to the bone defect of the subject are also provided. Methods of fixing or gluing natural or synthetic bone grafts using a handheld 3D printer to apply a filament or the printing material placed in a syringe over and around the defect or at the interface of a flap and the bone. Methods of printing a graft cage for retaining bone grafts and/or bone graft substitute in its desired location during healing for treatment of critical-sized segmental defects in long bones are provided.
