  • Varying density of a model for manufacturing a liner
    Patent number: 11957604
    Abstract: A system and method for method including receiving data representing coordinates of a shape of a body part, forming a model of a flexible inner liner based upon the received data, the flexible inner liner configured to be placed over the body part, receiving, as input, a thickness and an offset of the model of the flexible inner liner, assigning a default density to an internal structure of the model; and varying the default density of the model without changing an outer geometry of the model to create a modified model of the flexible inner liner.
    Type: Grant

  • Prosthetic limb socket with variable hardness
    Patent number: 10905568
    Abstract: A system and method for producing a customized prosthetic socket based on a digital representation of a residual limb that is used to form a digital model of a prosthetic socket. The digital model is customized to alter its internal structure to produce differing areas of flexibility and support while maintaining the overall geometry of the model and without having to use different materials. The digital model is converted for use with a three-dimensional printing or manufacturing device and then used to print the customized socket.
