4-D printing is additive manufacturing that prints objects capable of transformation and, in some cases, self-assembly.
CASE (computer-aided software engineering) is the use of a computer-assisted method to organize and control the development of software, especially on large, complex projects involving many software components and people.
Digital modeling and fabrication is a design and production process that marries 3-D modeling or computing-aided design (CAD) software with additive and subtractive manufacturing.
A digital twin is a virtual representation of a product that can be used in product design, simulation, monitoring, optimization and servicing. It requires three elements: the physical product in real space, its digital twin in virtual space and the information that links the two.
