Man-made synthetic polymers are almost as manifold as the natural ones, although the most progress in development only started about in the Second World War. Due to relatively long degradation profile PCL is suitable for use in tissues with longer regeneration process. It is a well known fact that polymers have gained an important place in day-to-day life for their specific properties which make them applicable in wide range of applications. Properties of resultant polyurethane depend on the ratios of these components. Thanks to ability of chitosan to interact with glycosaminoglycans (GAGs) scaffolds based on chitosan can have a direct impact on the modulation of cytokines and growth factors and thus local tissue regeneration. Besides using polymers, 3D printers are also capable of using other materials like ceramics, metals, glasses etc. Polymers, give the great opportunity to fulfill one of the main assumption of regenerative medicine and tissue engineering, which is formation of wholsome tissue in in vivo conditions. -sheet structures.

Collagen is ECM protein. Unlike conventional manufacturing, which starts with a solid block of material that is cut and shaped (i.e., subtractive), 3D printing only places material where it is needed (i.e., additive). SMPs have received considerable attention in medical technology, but so far little interest as engineering applications are concerned. We suppose that the quantity X of polymer (measured in mg) in a certain formulation is normally distributed. Examples of the most frequently studied synthetic biomedical polymers are presented below.

The very first reported synthetic polymer for medical use is poly (methyl methacrylate) (PMMA) by a British ophthalmologist, Sir Nicholas Harold, in 1949 for making intraocular lens [2]. The assembly of silk and the strength and resiliency of silk fibers are the result of large hydrophobic domains interspaced with smaller hydrophilic domains. Biodegradable polymers are a special class of polymer that breaks down after its intended purpose by bacterial decomposition process to result in natural byproducts such as gases (CO 2, N 2), water, biomass, and inorganic salts. It is formed by polymerization process with the action of thrombin and activated factor XIII, which convert fibrinogen into fibrin. Collagen fibers are the tissue structural framework and are responsible for suitable tensile strength. The biggest application for EAPs lies in their future use as actuators and sensors, which in turn opens up applications in the fields of electronics, medical, sensing and solar energy generation.
