Although there are several methods for producing a three-dimensional ceramic scaffold, most of these methods cannot completely mimic the bone structure. In this study, a bioglass scaffold was fabricated through selective laser sintering (SLS) with the addition of the iron element that could ascend the laser absorption rate with the improvement of the formability and mechanical strength of scaffolds. As a result, the laser absorption proficiency improved with an increase in the amount of iron added; a competent bioglass scaffold could be successfully manufactured with a 5% iron element addition at the energy density of 2.5 cal/cm2 (3-W power and 120 mm/s scan speed). In a comparison of scaffolds sintered with various parameters of the heat treatment, scaffolds that had favourable mechanical strength and cell survival rate could be acquired after sintering at 1100 °C. According to the result of the present study, a competent biocompatible bioglass scaffold could be obtained using the SLS process with the addition of the iron element and suitable post-processing parameters. ? 2020 Elsevier Ltd and Techna Group S.r.l. |
