![]() Based on the osteosarcoma cells proliferation experiment and mechanical testing of designed scaffold samples, it will be stated that it is likely not necessary to keep the recommended porosity of the scaffold for bone tissue replacement at about 90%, and it will also be clarified why this fact eliminates mechanical properties issue. We tested printing of scaffolds with different geometrical structures. ResultsĬommercially available 3D printer and Polylactic acid were used to create originally designed and possibly suitable scaffold structures for bone tissue engineering. Research presented in this article is in general focused on “scaffolding” on a field of bone tissue replacement. In this article we tested printing of clinically applicable scaffolds with use of commercially available devices and materials. However, this technique is still to solve various issues before it is easily used for scaffold fabrication. Most promising techniques seem to be Rapid prototyping due to its high level of precision and controlling. In recent years, research workplaces are focused on developing scaffold by bio-fabrication techniques to achieve fast, precise and cheap automatic manufacturing of these structures. During the cell growth gradual biodegradation of the scaffold occurs and the final product is a new tissue with the desired shape and properties. These are used for attachment and subsequent growth of appropriate cells. At present, Tissue engineering repairs damaged tissues and organs with artificial supporting structures called scaffolds. The primary objective of Tissue engineering is a regeneration or replacement of tissues or organs damaged by disease, injury, or congenital anomalies.
