Abstract

Since first introduced in the late 1960s, three-dimensional (3D) printing has gained great attention from academia and industry because of its potential hyper flexibility and precision nature in designing and manufacturing of any complex structural products. As a result of much effort, a number of 3D printing technologies have been developed so far, which can be categorized by seven major families depending upon the printing schemes and layering materials. In this article, the recent advances in the seven 3D printing families were critically reviewed from the views of pros and cons in the methodology nature, material availability, printed product size and quality, product properties performance, cost, and applicability. The global 3D printing market was also discussed, including 3D printer and layering material markets. In addition, perspectives were given for further advancing 3D printers in the repeatability and reproducibility, developing new layering materials with processability and property performances, building up and utilization of data bases on the process−morphology development−property relations, and reducing investment and production costs, which are necessary to expand global 3D printing market to all research and industrial fields.
