3D Printing in Biomedical Applications

Abstract

This study deals with the 3D Printing technology, a type of additive manufacturing in which the 3D object is imitated to be visual within the allocated period of time interval that resembles similar in considered aspects of real world object. The material used here includes powders of polymer mass that are solidified by directional laser heating. While talking about BIO-PRINTING, the material used is living tissues, calcium source, vascular tissue, placental fluid, embryonic stem cell etc., and the entire organ is regenerated from the tissue, which was printed in the enzymatic incubation medium. The organ is similar to the patient's organ; the patient's organ information is get read from many scanning devices. Coupling all the images will result in the three dimensional structure. The printing is done with the help of the 3D printer on the basis of obtained 3D image and the artificial organ (imitation of real organ) is being made. The making of organ is controlled by, speed of filling tissue, temperature at which the process is carried out, bonding agent to bond the tissues together, incubation medium, type of tissue, body immunity, stem cell growing phenomenon, filler head movement respective to all the axes, slicing path, etc.. The procedure is simple related to the rapid prototyping; the produced artificial organ (human bone, human kidneys, bladder, etc., can be replaced with the defected organ. Thus, the controlled action of all the parameters can lead to the organic replacement with the birth similar organs.
