Biostability and biodegradability are the two important parameters to be noticed to select a polymer … We know 27 types of collagen, wherein type I collagen is the most abundant. 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. Biodegradable polymers are generally used for this purpose. Nowadays, the 3D printing technology represents a big opportunity to help pharmaceutical and medical companies to create more specific drugs, enabling a rapid production of medical implants, and changing the way that doctors and surgeons plan procedures. It is shown up that biomedical polymers comprise not only bulk materials, but also coatings and pharmaceutical nano-carriers for drugs. Three-dimensional (3D) printing refers to a number of manufacturing technologies that generate a physical model from digital information. Molecular weight, cross-linking and polymer concentration affect mechanical properties of PEG scaffolds in tissue engineering. Polymers are now produced in great quantity and variety. as suture material also for long time . SMPs have received considerable attention in medical technology, but so far little interest as engineering applications are concerned. Submission of manuscripts is not limited to the following hot fields. One of the most prominent new uses of polymers in medical device development is in 3D printing. These polymers are biocompatible, biodegradable, non-toxic, low-immunogenic.

The M/G ratio, G-block length and molecular weight affect the physical and mechanical properties of alginate and resultant hydrogel. This cationic polymer can form electrostatic interactions with negatively charged cell surfaces and also display antimicrobial activity. Silk as a biomaterial. These polymers are known as soil conditioner and used for the following purposes in agriculture: Preventing soil erosion. There is subsequently an overview of the most frequently used polymer classes. The assembly of silk and the strength and resiliency of silk fibers are the result of large hydrophobic domains interspaced with smaller hydrophilic domains. Due to unfavorable degradation profiles combinations of polyurethanes with other biomaterials are made to improve degradation rate of polyurethane-based scaffolds. Polymers consist of large molecules made up of repeating structural units. Deacetylation is used due to  insolubility of chitin in common solvents and difficult processing. 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]. Polymers are incredibly diverse elements that represent such fields of engineering from avionics through biomedical applications, drug delivery system, biosensor devices, tissue engineering, cosmetics etc. A wide range of different polymers is available, and they have further the advantage to be tunable in physical, chemical and biological properties in a wide range to match the requirements of specific applications. From test equipment like vials and beakers to surgical instruments, catheters, and implants, plastics are used more and more for their high performance, lightweight, and lower costs. We know 27 types of collagen, wherein type I collagen is … 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). It has been suggested that this polymer display also anti-inflammatory and bacteriostatic action. The main body of the review then is structured according to the medical applications, where key requirements of the applications and the currently used polymer solutions are indicated. 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. The most common natural polymers are presented below. Polymers are becoming increasingly important in the field of drug delivery. Naturally, alginates occur as calcium, magnesium and sodium salts. Collagen fibers are the tissue structural framework and are responsible for suitable tensile strength. Therefore  fundamental constituents of polyurethanes are:  hard segment - diisocyanate, the soft segment - polyethers or polyesters and chain extenders. From surgical sutures to monitoring systems used in medical applications are made from polymers of various grades. We use polymers every day, for example in the form of plastics, coatings and paper, and in products such as nappies and shampoos. 3D printing can create many types of medical devices from metals, plastics, hydrogels, and even biological materials. • Polymer based LED. Silks are used as biomaterials because of their biocompatibility, controlled proteolytic biodegradability, impressive mechanical properties, morphologic flexibility and the ability to immobilize growth factor. 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. Figure 1. They are  much more reproducible and have better mechanical properties in comparison to natural polymers. Applications of synthetic polymers in clinical medicine. is cationic polysaccharide obtained from deacetylation of chitin built from (beta-1,4-linked N-acetylglucosamine units. The assembly of silk and the strength and resiliency of silk fibers are the result of large hydrophobic domains interspaced with smaller hydrophilic domains. Vepari, C., & Kaplan, D. L. (2007).
