3D Printing is a process of making three dimensional objects from a single file. In other word 3D printing is mentioned as Additive Manufacturing (AM). It turns 3D models into objects by building those layers. It makes a part layer-by-layer including material extrusion, binder jetting, material jetting and directed energy deposition this design is made in a computer aided design (CAD) file using a modeling program. Large 3D printers also available for industrial, education and demonstrative users, the prospects of 3D printing are growing even children’s can use this easily. The self-reinforced fantasy of a system of eternal growth can be overcome with the development of economies of scope
Types Of 3d Printing Technologies
Sterolithography (SLA), Digital light processing (DLP) Fused deposition modeling (FDM), Selective laser sintering (SLS), Electronic beam melting (EBM), Laminated object manufacturing (LOM),
A 3d printers is much like an inkjet printer operated from a computer. Fused deposition modeling (FDM) method was used to build up a 3Dmodel one layer at a time. FDM commonly used for modeling, prototyping, and production applications. It acts as a scaffolding to support the object. The FDM printer starts out as CAD files. This file must be converted to STL Format which 3D printer can understand
Merits And Demerits Of 3dprinters Limited Materials
It is easy to convert any design to prototype. It helps to lower the raw material wastage. Easy to use and secondary structures can be seen clearly. 3D printing could develop economies of scope.3D printing is in friendly file format. 3D printing gives students a new perspective with topographic maps. This can be used to make cases like computers and laptops. 3D printer was used to build open source robots. It also used for making organ 3D structure. 3D printers are utilized in manufacturing to print spare parts of air craft.
Accuracy is not assured in limited size. Duplication in drugs, it is very expensive fewer manufacturing jobs dangerous objects such as knives and guns can be created with very little or over sight, process is slow.
