The application of 3D printing spans a wide range of industries. The term "3D printing," on the other hand, refers to a far larger range of methods. The rapid expansion of the industry illustrates the applicability of 3D printing. Engineers are pushing the boundaries of 3D printing concrete by precisely automating the pouring process using computers and robotics, while scientists are working on more intelligent ways to 3D print complex polymers. The major 3D printer manufacturers emerge, new technologies improve, and 3D modeling tools debut, propelling additive manufacturing to new heights.
The 3D printing process is also known as 'additive manufacturing' since it entails constructing products from the ground up rather than cutting or milling a shape in a mold. Its benefits include minimal waste and the ability to print elaborate shapes that would be impossible to produce otherwise, such as intricate lattice systems. Sporting goods companies, aviation and aerospace companies, and medical device companies are all ready to capitalize. It is widely used and valued in enterprises such as prototyping and manufacturing, medical, construction, art education, and arts and galleries.

Excerpt from the Book
A. Where and When the Technology was developed
Although 3D printing was conceived in the 1970s, the first trials were conducted in 1981. Dr. Hideo Kodama of the Nagoya Municipal Industrial Research Institute published details of a 'rapid prototyping' technique in May 1981. This research was the first to describe the layer-by-layer approach fundamental to 3D printing and SLA (or Stereolithography): a UV light polymerized a photosensitive resin. Stereolithography (SLA) is an industrial 3D printing that can produce concept models, cosmetic prototypes, and sophisticated parts with complex geometry in as little as one day. SLA allows for extensive materials, exceptionally high feature resolutions, and high-quality surface finishes (Protolabs). His research involved printing photopolymers using a technique that predated Stereolithography, and he also discussed cross-sectional slices of the layers that formed the 3D object. On the other hand, he did not submit his patent application on time and thus was never granted the patent. This is made worse by (unconfirmed) claims that Dr. Kodama is a trained patent lawyer.
