1. A process of designing and manufacturing a prosthetic socket comprising steps of:
a) obtaining physical data about a patient with a residual limb,
b) obtaining or creating a digital representation of a modified area of the residual limb,
c) axially adjusting the prosthesis for a structural design of the 3D printed prosthetic socket,
d) creating the structural design of the 3D printed prosthetic socket based on the obtained physical data about the patient and based on the digital representation of the modified area of the residual limb, and based on the axial adjustment of the prosthesis,
e) sending the data about the structural design of the prosthetic socket to the 3D printer,
f) making the prosthetic socket using 3D printing,
wherein the step of axially adjusting the prosthesis for the structural design of the 3D printed prosthetic socket includes virtual spatial translational or rotational movements of selected prosthetic parts and the prosthetic socket for optimal load transfer from the residual limb to the prosthesis, and the structural design of the 3D printed prosthetic socket is based on the virtual axial adjustment of the prosthesis.
 
10. A computer device for carrying out the process of claim 1, the computer device containing a software application comprising a method of designing and manufacturing a prosthetic socket comprising steps of:
a) obtaining physical data about a patient with a residual limb,
b) obtaining or creating a digital representation of a modified area of the residual limb,
c) axially adjusting the prosthesis for a structural design of the 3D printed prosthetic socket,
d) creating the structural design of the 3D printed prosthetic socket based on the obtained physical data about the patient and based on the digital representation of the modified area of the residual limb, and based on the axial adjustment of the prosthesis,
e) sending the data about the structural design of the prosthetic socket to the 3D printer,
f) making the prosthetic socket using 3D printing,
wherein the step of axially adjusting the prosthesis for the structural design of the 3D printed prosthetic socket includes virtual spatial translational or rotational movements of selected prosthetic parts and the prosthetic socket for optimal load transfer from the residual limb to the prosthesis, and the structural design of the 3D printed prosthetic socket is based on the virtual axial adjustment of the prosthesis,
the software application further comprising a database of prosthetic parts and an interactive configurator comprising a patient data collection module, wherein the interactive configurator further comprises a module for selecting the corresponding prosthetic parts, a module for displaying the mutual location of the selected prosthetic parts and the prosthetic socket, and a module for determining the virtual axial adjustment of the prosthesis.
