In today's highly competitive worldwide market, product businesses are always looking for new ways to cut lead times and handle customized new product innovations that satisfy all consumer requirements, such as product quality, cost, and aesthetics. In general, product companies have adopted a variety of new technologies such as Computer Aided Design (CAD), Computer Aided Manufacturing (CAM), Computer Aided Engineering (CAE), Rapid Prototyping (RP), Digital Manufacturing (DM), Additive Manufacturing (AM), and others that offer business benefits by shortening the product development cycle. This technical note aims to describe the evolution of Information Communication Technology (ICT) in manufacturing, outlining their characteristics as well as digital manufacturing concepts. The technologies discussed in this paper include CAD, CAM, CAE, RP, DM, Product Lifecycle Management (PLM), Collaborative Engineering (CE), Reverse Engineering (RE), simulation, and ecommerce (Web Technology) systems. These technologies are discussed in relation to digital manufacturing ideas.

CAD, CAE, CAM, DM, ICT, PL, Reverse Engineering (RE), Simulation.
