Additive smoothing of sharp concave edges on designed 3D printable polygonal mesh models

A method for fabricating a personalized medical device, comprising:

• receiving a template design of a medical device;
• acquiring an image including a patient anatomical geometry;
• combining the received template design of the medical device with the acquired image including the patient anatomical geometry to create a custom medical device design;
• identifying, within the custom medical device design, a region of interest encompassing a sharp concave edge using one or more seed points received from a user;
• performing surface smoothing of the custom medical device design within the region of interest to bolster a thickness of the custom medical device design within the region of interest;
• and
• three-dimensional (3D) printing the surface-smoothed custom medical device design.

A computer system comprising:

• a processor;
• and
• a non-transitory, tangible, program storage medium, readable by the computer system, embodying a program of instructions executable by the processor to perform method steps for designing a personalized medical device, the method comprising:
• receiving a template design of a medical device;
• acquiring an image including a patient anatomical geometry;
• combining the received template design of the medical device with the acquired image including the patient anatomical geometry to create a custom medical device design;
• identifying, within the custom medical device design, a region of interest encompassing a sharp concave edge using one or more seed points received from a user;
• performing surface smoothing of the custom medical device design within the region of interest to bolster a thickness of the custom medical device design within the region of interest;
