عنوان مقاله [English]
light-based three dimensional (3D) printing processes which are based on the use of light-sensitive monomers or oligomers, are the most versatile and interesting technique due to the unique potential to design structures with complex geometry, the ease of the process, the availability of the required compounds as well as the feasibility of tailoring materials to achieve the required properties. In this approach, photoinitiators are considered the key elements in the success of this process, and several types of research have been performed to introduce initiators with enhanced efficiencies. This article reviews the types of photoinitiators used in 3D printing technology highlighting the researches carried out to transfer the adsorption region of the compounds from the ultraviolet to the visible region. In addition, water-soluble photoinitiators are of great interest for use in the bio-printing of hydrogel systems, which are reviewed in this review article. The success in developing the 3D printing process and fabrication of constructs with suitable mechanical properties as well as resolution requires familiarity with the key elements involved in the process, and therefore, one of the most important factors is reviewed here.
