Three-dimensional (3D) printing is introducing revolutionary changes to manufacturing processes. In the beginning, 3D printers were used only for small-scale trial production. However, more and more 3D printing service providers are now mass-producing their products. Nowadays, information companies, 3D photo studios, supermarket chains, and other shops are providing limited 3D printing services. Most of the existing studies on 3D printing for manufacturing have focused on technical concerns such as the use of various materials for printing, modeling and simulation, and how to inspect a 3D-printed product. However, there are managerial concerns that warrant attention, such as 3D-object database management, lean manufacturing, digital rights management, e-commerce applications, and globalization and deglobalization (Chen and Lin, 2017). This special issue is intended to provide technical details of managing 3D printing technologies for manufacturing. According to strict review criteria, thirteen articles from researchers around the world were accepted.
