Research and Application of 3D Printing Technology in the Field of Pharmaceutical Preparation

As a new three-dimensional molding technology, 3D printing technology was firstly applied in such fields as architecture, astronautics and aerospace, and industrial metallurgy, and has been gradually applied to the pharmaceutical industry. By introducing the working principles and features of each one of the five types of 3D printing technology, including selective laser sintering, stereo lithography apparatus, ink-jet printing, fused deposition modeling and semi-solid extrusion, and discussing through analysis the advantages, challenges and prospects in the field of pharmaceutical preparation, this review aims to provide a new direction for the application of 3D printing technology in the field of pharmaceutical preparation.
