Additive manufacturing is a source for readily available customized parts. Innovation within this field focuses on improving techniques of increasing accuracy, precision, and speed. In biotechnical industries, Nylon 12 is used for its biocompatibility. This study focuses on the effects 4 orientations, 8 fixed plane positions, and 5 print heights have on mechanical reliability of 3D printed Nylon 12. Data of 40 specimens per orientation were reviewed. The printed specimen were confirmed to be Nylon 12 using differential scanning calorimetry and fourier transform infrared spectroscopy. Tensile pull tests were performed on each specimen and compared amongst orientations and locations within the prints. Although mechanical properties of the parts are within 95% performance in conventional molded Nylon 12, other tests such as compression, torque, and biocompatibility must be conducted before considering this approach for bone implants.
