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.
