Interesting Facts about 3D Printing and How it Works The 3D printing industry has become very popular all over the world, and it growth is expected to increase in revenue and transforms other industries and is expected to produce various changes in our lives, work and leisure time in the coming years. 3D printing is defined as the various processes used by the people to create or produce a three-dimensional object, and that can be done under a computer control. Additive manufacturing or AM, is another term used by the people that refers to 3D printing, and the products of the said industry can be in any geometry, shape or forms, and such products can be created by the use of a digital model data from a 3D model, or from an electronic data source, such as an additive manufacturing file or AMF file. Initially, the term 3D printing refers to the process that deposits a binder material onto a powder bed with the use of an inkjet printer heads which is formed layer by layer, but nowadays, such term is being used in famous vernacular to circumscribe a much wider variety of techniques of the additive manufacturing. The 3D printing industry are using seven processes or categories to produce their products and services, such as the sheet lamination; material extrusion, which includes FFF or fused filament fabrication and FDM or fused deposition modeling; powder bed fusion, which includes SLS or selective laser sintering; material jetting; binder jetting; directed energy deposition; and the vat photopolymerization, which includes SLA or stereolithography, CLIP or continuous liquid interface production, and DLP or digital light processing. A 3D printable models can be produced or created with the use of different kinds of tools or equipment, like plain digital camera, photogrammetry software, CAD package or computer-aided design package, and the 3D scanner. 3D scanning is described as the process that involves the act of collecting digital data on the shape, appearance or form of a real-life object or items to produce a digital model based on it. Some of the popular examples of the products and applications of the 3D printing industry include for healthcare, such as 3D printing with human tissue and 3D printed prosthetics; rapid prototyping; for entertainment, such as the props for movies; architectural models and maquettes; replicating ancient artifacts in archaeology; reconstructing fossils in paleontology; reconstructing severely damaged evidences from any investigation on a crime scene; and reconstructing body parts and bones in forensic pathology. There are a lot of companies, nowadays, that offers 3D printing services, and the people who wants to hire their help can find them through the word of mouth of their previous clients, through the recommendations of friends and colleagues, or through the use of the internet.
