Abstract
In Additive Manufacturing (AM) parts are produced by adding material layer-by-layer. AM technologies play an increasingly important role in the biomedical industry, like in tissue engineering (TE). In TE new and functional living tissue is fabricated using living cells, which are usually associated with a scaffold or 3D structure to guide tissue development aiming at tissue regeneration. AM technologies offer excellent potential for fabricating TE scaffolds due to their ability to create structures with complex geometry and internal architecture with a high degree of automation, good accuracy and reproducibility, as opposed to conventional scaffold fabrication methods. The main goal of this research project is to investigate the Selective Laser Sintering (SLS), an AM technology, of poly(vinyl alcohol) (PVA) polymer material, through experimental tests, with the purpose of fabricating scaffolds for the application in in vitro studies. The influence of the number of scans on the surface microstructure and PVA material properties is being investigated. The number of scans varied from 1 to 6. It is possible to conclude that the number of scans has a strong influence on surface microstructure of the laser sintered samples and could also change PVA material properties after SLS.
