Additive manufacturing (3D printing): A review of materials, methods, applications and challenges

3D printing (additive manufacturing) is now widely applied in the electronics, automotive, aerospace, medical engineering and other fields¹. Due to high precision, high efficiency for single product and convenient operation, 3D printing gets more and more attention from the whole word. In recent years, this technology has been widely used in the tissue engineering. The term coined for the printing of tissues using these types of approaches is bioprinting, cell printing or even organ printing². Bioprinting uses a computer-controlled 3D printing device to accurately deposit cells and biomaterials into the models of organs³. It has less danger of organ transplant rejection than traditional treatment of grafting, which is limited by the number of donors. Nowadays several bioprinting progresses have been demonstrated, such as bionic ears⁴, multilayered skins⁵, artificial bones⁶, vascular tissues⁷ and cartilaginous structures⁸.
During printing, suitable viscosity is very important. Deformation and collapse will be easily happened when printing low viscosity materials. On the other hand, nozzles will be easily jammed when high viscosity materials are printed. There must be a lot projects to be researched during 3D Printing.
