An anchor system for securing suture tissue to bone. The system includes an anchor (100,200,300) and an inserter (400,600). The anchor (100,200,300) is printed from a polymer by selective laser sintering in accordance with a CAD file having a geometric description of the anchor (100,200,300). A socket (130,230,330) at the proximal region of the anchor (100,200,300) has a cross-section that has a width in a first dimension D1. The system includes an inserter (400,600) having a protrusion being configured to matingly engage with the socket (130,230,330) . The protrusion defines a cross-section that decreases progressively in width in the dimension D1 along the protrusion length distally from a base of the protrusion toward the distal tip of the protrusion.
