There are seven additive manufacturing production techniques. Each vary due to materials, layering, and machine technology needed. Each vary due to materials, layering, and machine technology needed. EWI specializes in all seven, and can help your team identify, design and implement the process that''s right for your application.
Terminology: "Additive manufacturing" is a broader term encompassing several techniques and processes for building objects layer by layer from digital designs. "3D printing" is a subset of additive manufacturing, typically associated with desktop or hobbyist-level printers using fused deposition modeling (FDM®) or similar technologies.
Additive manufacturing reduces energy use by 25% and can cut waste and materials costs by up to 90% 1, compared to traditional manufacturing methods. Additionally, this method also has the ability to improve energy productivity, allow for greater design flexibility and reduce production time—all while creating high-impact job
Although media likes to use the term "3D Printing" as a synonym for all Additive Manufacturing processes, there are actually lots of individual processes which vary in their method of layer manufacturing. The
To additive manufacturing newcomers, material extrusion AM processes are likely to be the most recognisable, interchangeably referred to as FDM (Fused Deposition Modelling) or FFF (Fused Filament Fabrication). ''Extrusion'' is defined as ''the process of forming something by forcing or pushing it out, especially through a small
3-D printing is an additive manufacturing (AM) technique for fabricating a wide range of structures and complex geometries from three-dimensional (3D) model data. The process consists of printing successive layers of materials that are formed on top of each other. This technology has been developed by Charles Hull in 1986 in a process
Fig. 1 represents the how additive manufacturing methods are contributing in mass customization level in industries. Since the inception of additive manufacturing technique, the materials and its adaptability in printing always poses a challenge. The material concrete, which was once only used in construction, has
Additive manufacturing encompasses a set of low-cost and highly versatile tools used to prototype and fabricate three-dimensional (3D) objects with ease. In most of the additive manufacturing techniques, materials are deposited layer by layer until a 3D object is reproduced. Several additive manufacturing techniques have been
In recent years, both academically and industrially, additive manufacturing (AM) has experienced rapid expansion because of its capability of producing customized products of intricate shapes. 3D printing has evolved as a promising technology for the creation of engineering parts or applications, as it is an additive technique, unlike
The electron beam DED AM techniques, Sciaky''s EBAM (electron beam additive manufacturing) and NASA''s EBF 3 (electron-beam freeform fabrication), employ an electron beam as an energy source to melt the metal wire feedstock to deposit lines [[111], [112], [113]]. WAAM (wire arc additive manufacturing) is an electric arc direct

Using computer aided design (CAD) or 3D object scanners, additive manufacturing allows for the creation of objects with precise geometric shapes. These are built layer by layer, as with a 3D printing process, which is in contrast to traditional manufacturing that often requires machining or other techniques to remove surplus material.
2. Powder Bed Fusion. Powder bed fusion (PBF) refers to a range of additive manufacturing technologies that fuse powders using a high-powered focused energy source. The energy source can be a laser (SLM or DMLS) or electron beam (EBM). Both metal and plastic powders can be used with PBF.
Additive manufacturing (AM) has revolutionized part design and fabrication across numerous industries. As new techniques emerge, so do new terms – although the underlying processes are often similar. To shed light on this rapidly-evolving field, we''ve put together a comprehensive guide to the seven key AM technologies as
