Abstract
EN This research explores the possibilities of realizing pelvic bone structures by 3D printing methods, focusing on all stages of developing of a new product, starting with the designing process of the structure, continuing with finite element analysis, and ending with manufacturing and testing steps that are necessary to be done in the end for validating of the research. Key elements that have been considered in the realized research include an exploration of pelvic anatomy, existing prostheses, and relevant research, with a primary focus on mimicking spongy tissues. The design phase introduces circular and square porous structures which have been integrated into test samples, alongside the creation of a pelvic bone model that has been realized by 3D printing methods. The manufacturing process of samples and realized prototype was realized by Fused Deposition Modeling using biodegradable Polylactic Acid (PLA) material, the experimental part being followed by mechanical testing that has been performed using the realized samples to determine the compressive, tensile and flexural strength characteristics. Finite Element Analysis which has been realized has revealed the superior mechanical characteristics of the circular porous structure, characteristics reached through mechanical testing, being further on used to estimate the mechanical behavior of a pelvic bone in the end. The research presented in the paper ends with the 3D scanning processes of pelvic bone and an acetabular cup that were realized by 3D printing methods, aiming to assess the clearance between these elements, emphasizing the potential of using the 3D printing methods to produce such porous structures that mimic the pelvic bone structure in the end.
