Abstract

The aim of this study is to obtain the artifial first metatarsal bone model that is similar material

properties with the real bone. It is difficult to find the real bone for biomechanical test and the

bone model is also expensive. This study aimed to develop an easy-to-manufacture, easy-tocustomize

and inexpensive method. 3D printer tecnology was used to produce the artificial bone

model. The bone mechanical properties were calculated via MIMICS software using computer

tomography images . 3D bone model was produced in different infill density and infill pattern

to determine the real bone mechanical properties using 3D printer. The infill density of the bone

model was adjusted as 20%, 40% and 60%. Five different infill pattern types as grid, cubic,

triangle, trihexagon and gyroid were used. The produced models were subjected to torsional

test and the elasticity modulus of all models were obtained. The results of the elasticty modulus

of all produced (artificial) and modelled (calculated) bone were compared and the optimum

bone model was obtained. The optimum infill density and infill pattern was determined as %40

and trihexagon, respectively.
