ROXANA MICLAUS, ANGELA REPANOVICI, NADINNE ROMAN BIOMATERIALS: POLYLACTIC ACID AND 3D PRINTING PROCESSES FOR ORTHOSIS AND PROSTHESIS Since the development of 3D printing, over the past decades, the domain of application has evolved significantly! Concerning the orthosis and prosthesis manufacturing, the 3D printing offers many possibilities for developing new medical devices for people with disabilities. Our paper wish to synthetize the main 3D printing methods and the biomaterial properties which can be used in orthosis and prosthesis manufacturing, like polylactic acid or acrylonitrile butadiene styrene. Fused Deposition Modeling and Stereo lithography are most used for medical devices manufacturing and usually using polylactic acid, considering the properties of this polymer and de organic componence.
