Abstract:
The emergence of diseases caused by the advent of human aging has led to the development of materials in bone tissue engineering (BTE) that can aid in the development of clinical treatments. Among these materials is the development of synthetic bone grafts through additive manufacturing. In this study, the scaffolds were developed by fused deposition modeling (FDM) using polylactic acid (PLA) doped with hydroxyapatite (HA) extracted from the scales of the pirarucu (Arapaima gigas). Fourier transform infrared spectroscopy (FTIR) analysis reveals bands at 1096 cm-1; 1018-1011 cm-1, 602 - 555 cm-1 that are attributed to calcium phosphate and hydroxyapatite minerals. Thermal analysis reveals four periods of weight loss, related to moisture loss, elimination of organic compounds, carbonation and removal of hydroxyls from HA sites. The addition of HA resulted in a decrease of 20.38% in compressive strength and 25.67% in apparent compressive modulus. Obtaining compressive strength of 3.14 MPa and 2.5 MPa, respectively, for samples SFP and SF1H and, respectively, compressive modulus of 108.55 MPa and 80.68 MPa.
