Interesting Facts about 3D Printing and How it Works
One of the latest industry, nowadays, is the 3D printing industry and it has become very popular worldwide that it is expected to grow or increase in revenue in the future, for it produced various changes in the lives, play and work of the people and transforms some other industries. 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. Another term that refers to 3D printing is additive manufacturing or simply as, AM, and the products created in such processes can be in any form, geometry or shape, and that is through the use of a digital model data from an additive manufacturing file, from a 3D model, or from any electronic data source. 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 seven processes or categories of 3D printing or additive manufacturing are the powder bed fusion, which includes SLS or selective laser sintering; material jetting; binder jetting; directed energy deposition; vat photopolymerization, which includes SLA or stereolithography, CLIP or continuous liquid interface production, and DLP or digital light processing; sheet lamination; and the material extrusion, which includes FFF or fused filament fabrication and FDM or fused deposition modeling.
The various tools or equipment used by the industry in producing or creating 3D printable models include the CAD package or computer-aided design package, the 3D scanner, plain digital camera, and photogrammetry software. The process which involves the act of collecting digital data on the form, shape or appearance of a real object or items to create a digital model based on it, is called as 3D scanning. Several examples of the application and products produced by the 3D printing industry are the reconstruction of body parts and bones in forensic pathology; 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; and the reconstruction of severely damaged evidences from any investigation on a crime scene. 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.
