Disclosed is a dip-coating method as a method of coating an outer surface of a target mold including steps of: preparing and putting a supporting liquid in a container; applying a coating material to the target mold; dipping the target mold in the supporting liquid; shaking the target mold surrounded by the coating material in the supporting liquid; curing the coating material surrounding the target mold in the supporting liquid; and taking out the coated target mold from the supporting liquid.

A method for forming a prosthesis comprising a bone-like portion and a cartilage-like portion can comprise additively manufacturing a first positive mold in accordance with a portion of a first three-dimensional model of a portion of a bone. A first negative mold can be formed from the first positive mold. The bone-like portion can be created within the first negative mold. A second positive mold of the bone and a cartilage can be additively manufactured from a second three-dimensional model. A portion of the second three-dimensional model can correspond to a portion of the first three-dimensional model. A second negative mold can be formed from the second positive mold. The bone-like portion can be positioned in the second negative mold so that the second negative mold and the bone-like portion can define a cartilage space that can be filled with a material to form the cartilage-like portion of the prosthesis.

The present invention relates to a suspension comprising 50-95% by weight of the total suspension (w/w) of at least one metallic material and/or ceramic material and/or polymeric material and/or solid carbon containing material; and at least 5% by weight of the total suspension of one or more fatty acids or derivatives thereof. In addition, the invention relates to uses of such suspension in 3D printing processes.

The invention relates to a process of designing and manufacturing a tailored 3D printed or standard prosthetic socket for a residual limb with a 3D printed distal end, and a computer device for carrying out the process. The process includes obtaining a digital surface of the residual limb and information about the patient, possibly altering the digital surface of the residual limb, creating a shell of the prosthetic socket comprising the altered digital surface of the residual limb, virtually spatially arranging the prosthetic socket including virtual spatial translational or rotational movements of selected prosthetic parts and the prosthetic socket for optimal load transfer from a residual limb to the prosthesis, wherein the structural design of the prosthetic socket is based on the virtual axial adjustment of the prosthesis.

A method of making a thermoplastic gel prosthetic liner for use with a prosthetic assembly that acts as the interface between the residual limb of an amputee and the socket assembly. The prosthetic liner comprises an open proximal end, a closed distal end, and sidewalls comprising an inner layer of molded thermoplastic gel. The thermoplastic gel is molded over a mandrel that has been sandblasted using #36 grit and, optionally, #320 grit at 100 psi so as to form microcraters and reduce the coefficient of static friction.

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.

Computer implemented methods of producing a bone graft are provided. These methods include obtaining a 3-D image of an intended bone graft site; generating a 3-D digital model of the bone graft based on the 3-D image of the intended bone graft site, the 3-D digital model of the bone graft being configured to fit within a 3-D digital model of the intended bone graft site; storing the 3-D digital model on a database coupled to a processor, the processor having instructions for retrieving the stored 3-D digital model of the bone graft and for combining a carrier material with, in or on a bone material based on the stored 3-D digital model and for instructing a 3-D printer to produce the bone graft. A layered 3-D printed bone graft prepared by the computer implemented method is also provided.

A method of fabricating a casting, the method including applying a substrate to a sacrificial mold, the sacrificial mold including a shaped non-planar receiving surface to receive the substrate and provide a casting of the substrate having a shaped structure corresponding to the receiving surface; and subjecting the sacrificial mold and casting to freeze drying conditions and sublimating the sacrificial mold from the casting to form a cast article including the shaped non-planar structure.

An additive manufacturing system and method for making components having filaments formed by elastomeric materials. A liner includes the filaments formed by an elastomeric material and is adapted for a prosthetic device system. The filaments form an elastomeric lattice structure and solid layers or features and define a ventilated structure permitting a transfer of air and moisture from an interior volume of the liner to an exterior or ambient liner. The liner may incorporate an adhesive and a textile layer secured to the elastomeric lattice structure and further define recesses and other features for improving a liner.

A build-plate with integrally-formed spinal implant constructs and a method used in forming spinal implant constructs on the build-plate and machining the spinal implant constructs formed on the build-plate to manufacture spinal implants is provided. The spinal implant constructs can be formed via additive manufacturing processes by adding material to an upper surface of the build-plate, and then the spinal implant constructs can be subjected to subtractive manufacturing processes to form the spinal implants.
