The article focuses on additive manufacturing (AM) or also known as three-dimensional (3D) printing as an alternative for rapid prototyping. It says that AM is use in stereo lithography and selective laser sintering wherein the shape defined by computer-aided design (CAD) is achieved through deposition of various materials and use of lasers to fuse the layers. It mentions the increase trend of using bonded sand as build material.

RAPID prototyping, MANUFACTURING processes, PROTOTYPES, NEW product development, and METAL castings
The article offers information on rapid prototyping, a manufacturing concept which do not necessarily involve metal casting that develops physical prototypes of finished products before starting series production. It presents a scope of possibilities for metal casting operations in theory and practice. It notes that various technologies such as stereolithography and fused deposition modeling are processes wherein a prototype structure is built in a material that can hold the desired shape.
