Abstract: The invention is a method of designing and manufacturing a 3D printed prosthetic socket or a standard prosthetic socket with a 3D printed distal end, comprising a step of obtaining physical data about a patient with a residual limb and a step of creating a structural design of the 3D printed prosthetic socket or standard prosthetic socket with the 3D printed distal end. The step of creating the structural design of the 3D printed prosthetic socket (3) or standard prosthetic socket with the 3D printed distal end comprises a step of determining the bulk density of the structure of the prosthetic socket between a shaped area for positioning a linking part of the liner and a distal planar area for mounting a linking adapter of the socket directly proportional to at least one of the data from a set including at least weight, patient's degree of activity, length of the residual limb, length of the prosthesis, size of the prosthetic foot, and angle between the axis of the limb and the axis of the prosthesis.

Abstract: 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.

Abstract: The invention is a 3D printed prosthetic socket for a residual limb consisting of a 3D printed shell. The 3D printed prosthetic socket comprises a distal end adapted for linking the interconnecting adapter of the socket and a proximal end with an opening adapted for inserting the limb. The 3D printed shell comprises a first housing of the socket comprising an inner wall, wherein between the first housing and the second housing, there is an air gap. The distal end adapted for linking an interconnecting adapter of the socket, the first housing and the second housing are made of single 3D printed part, wherein the first housing comprises an elastic region comprising set of shaped openings, and the first housing is connected with the second housing through a reinforcing structure composed of ribs.

Abstract: The invention is a 3D printed prosthetic socket for a residual limb consisting of a 3D printed shell. The 3D printed prosthetic socket comprises a distal end adapted for linking the interconnecting adapter of the socket and a proximal end with an opening adapted for inserting the limb. The 3D printed shell comprises a first housing of the socket comprising an inner wall and an outer wall, wherein the first housing of the socket comprises a rigid region having, in the direction perpendicular to the inner wall, the rigidity of the rigid region and an elastic region having, in the direction perpendicular to the inner wall the rigidity of the elastic region. The rigidity of the elastic region is smaller than the rigidity of the rigid region, wherein the elastic region comprises a set of shaped openings and is adapted for softening the contact of the residual lower limb with the prosthetic socket, wherein the 3D printed shell is made of a single 3D printed part.

Abstract: An object of the invention is a 3D printed ankle and foot orthosis comprising a 3D printed shell (1), wherein the shell (1) comprises a bottom part (2) and a top part (3), and an anterior piece (9) located between a medial part (4) and a lateral part (5), wherein the anterior piece (9) is adapted to encircle the anterior region (10) of the foot and ankle between the medial part (4) and the lateral part (5), wherein the anterior piece is formed of a single material, wherein the medial side (12) of the anterior piece and the lateral side (13) of the anterior piece each comprise at least one transverse cutout (14) from the margin of the medial side (12) of the anterior piece and the lateral side (13) of the anterior piece towards a central part (11) of the anterior piece, wherein the transverse cutouts (14) are adapted to increase the flexibility of the central part (11) of the anterior piece at the point between the transverse cutouts (14).
