Abstract

The focus of this research is the ability to manufacture, when using layer base production methods, the medical insert known as ITAP used for prosthetic attachment in a femur. It has been demonstrated using computational modelling that a 3-dimensional build of the ITAP has the lowest stress present...

description The focus of this research is the ability to manufacture, when using layer base production methods, the medical insert known as ITAP used for prosthetic attachment in a femur. It has been demonstrated using computational modelling that a 3-dimensional build of the ITAP has the lowest stress present when the honeycomb infill pattern’s percentage is set at 100%, with the ITAP being constructed on a horizontal printing bed with the shear forces acting adjacent to the honeycomb structure. The testing has followed the British standard ISO 527-2:2012, which shows a layer base printed tensile test sample, with a print setting of 100% infill and at a side print orientation; this was found to withstand a greater load before failure than any other printed test configuration.
