In tissue engineering, scaffolds are used for cell culture. Biodegradable scaffolds gradually degrade and are replaced by new formed tissue. Automatic manufacturing, e.g. by Rapid Prototyping, enables to prepare scaffolds of precise structure, shape and size. In the work we have tested commercially available 3D printer and polylactic acid was used as a tested material. Structures with different geometry have been prepared and tested with osteosarcomas cells. Moreover, biomechanical properties of the scaffolds have been tested. Porosity lower than 90% did not affect cell proliferation, and scaffolds demonstrated better biomechanical properties. Our work showed possibilities and limitations during the scaffolds preparation using Rapid Prototyping.
