Additive manufacturing, also known as 3D printing or rapid prototyping, is a technology with an elaborate history. Since the first patent was filed in the 1980s, different companies have fought for the first-place position to become the brand name for 3D printing. As patents expired and became available to the masses, a new industry frontier
Abstract. 3D printing is an additive manufacturing (AM) technique that has quickly disrupted traditional design and manufacturing strategies. New structures can be manufactured that could not be fabricated using other methods. These new capabilities are considered by many to hallmark a historic shift representative of a new industrial
This article presents a brief history of additive manufacturing (AM). It begins by describing additive manufacturing prehistory, dating back to 1860, which is characterized by additive part creation without the use of a computer. The article then discusses the development of additive manufacturing processes occurring in the period from 1968 to
Additive manufacturing, also known as 3D printing, is a cutting-edge manufacturing process revolutionizing industries worldwide. It involves building objects layer by layer using digital models, unlike traditional subtractive methods. Additive manufacturing enables the creation of complex geometries that are challenging or
As human beings, we have a moral responsibility to act in a manner that takes the wellbeing of humans and Earth into consideration. When building, we must consider two things: the health of the workforce associated with construction and the state of the planet after building. Many engineers in the past have made groundbreaking
In this study, a multi-phase field method coupled with a CALPHAD database is developed to simulate the solidification microstructure evolution of a practical Ni-based alloy. Thermal analyses of a wire arc additive manufacturing model were performed by the process modeling of multi-pass depositions with a running cyclic arc.
Additive Manufacturing in the 1980s. The foundation for additive manufacturing was laid in 1980 when Dr Hideo Kodama, a researcher at the Nagoya Municipal Industrial Research Institute, filed the first AM patent. Kodama''s idea was to use a container of photopolymer material and expose it to light to create prototypes.
Additive manufacturing (AM), often referred to as rapid prototyping, freeform fabrication, or 3D printing, is defined as "the process of joining materials to make objects from 3D model data, usually layer upon layer, as opposed to subtractive manufacturing methodologies" like machining [1, 2].Various industries refer to the
Additive manufacturing of metallic alloys involves non-uniform temperature distributions and rapid thermal cycles that result in microstructures featured with anisotropy, which differ drastically from their cast or wrought counterparts.

This chapter traces the evolution of additive manufacturing (AM) from a rapid prototyping technique to a disruptive technology that impacts various industries. It reviews the latest research and expert opinions on the effects of AM on industrial, societal, and environmental aspects. It also explores 4D printing (4DP), a novel branch of AM that
Additive manufacturing (AM) using 3D printers is attracting attention as one tool to promote the digital transformation (DX) of the manufacturing industry. DX is not simply the introduction of digital tools, but refers to the transformation of business models through the use of digital technology. AM, also known as 3D printing, is defined by
The scientific community is and has constantly been working to innovate and improve the available technologies in our use. In that effort, three-dimensional (3D) printing was developed that can construct 3D
A Cellular Automata based approach was adopted to simulate grain evolution in metal melting based additive manufacturing processes. The influence of different scan patterns on grain morphologies was demonstrated. The simulated results matched a wide variety of microstructure data reported in the literature for SLM, DED,
December 1, 2011. Editor''s note: This commentary was sponsored as part of DE''s Visionary Voices section. Additive manufacturing (AM) is instrumental in bringing products to life. Its role now spans concept development to manufacturing. While many of today''s conversations turn to the amazing ability to manufacture end-use items with little
1. Introduction. Additive manufacturing is a disruptive technology that directly prints three-dimensional (3D) components layer by layer according to digital models [1], [2], [3], [4] pletely different from conventional fabrication methods, such as casting, forging, and machining, additive manufacturing is a near-net-shape fabrication process
Additive manufacturing (AM) technology has rapidly evolved with research advances related to AM processes, materials, and designs. The advantages of AM over conventional techniques include an augmented capability to produce parts with complex geometries, operational flexibility, and reduced production time. However, AM

Polymer additive manufacturing (PAM) may be used to produce delicate and complicated structures for the aerospace industry, structural models for the building industry, art replicas that are not real, and tissue and organs for use
Introduction. Additive manufacturing (AM), also known as 3D printing, is a promising technology for rapid production of net-shaped or near-net-shaped components from powders or wires melted by a
The Additive Manufacturing (AM) field is revolutionizing the industrial sector in different areas such as automotive, aeronautics, medicine, etc. Many patents about AM processes were granted at the end of the XXth century. However, until their release, the use of AM was very limited, mainly because of the high cost of the equipment.
Additive methodologies are overcoming the disadvantages of subtractive fabrication techniques, opening up doors to greater freedom in design, materials, and applications for a wide range of industries. A "cross- pollination" of conventional and futuristic approaches will lead to a better product. Meet the author.
