A Short Review on Bio-compatible/Bio-degradable| Photopolymers for Stereolithography Bio-3D Printing

Abstract

One of the important procedures in Bio-3D printing is to print/fabricate the scaffold for tissue engineering. A scaffold is a porous biomedical implant, which provides a short-term support to seeded cells in order to direct the formation of new tissues. The scaffold must be non-toxic, biodegradable, biomechanical properties, specific chemical composition and have a precisely defined pore size and geometry. For this reason, it is very important to fabricate scaffolds with high precision. In this review, 3D printing of biomedical scaffolds using photo polymerization process is briefly reviewed. As per requirements of tissue engineering, the choice of best 3d printing method and photopolymer were discussed. Apart from this bio-3D printing application, the bio-compatible photopolymer will be widely used in dental application, like the direct printing of aligner in orthodontics and temporary denture fabrication.
