What are the different types of rapid prototyping?

Fast prototyping is a family of additive production processes used to build prototype models. These processes are known as additive methods, as the material is added to the model during the design rather than cut off from a solid block. Members of this family generally use selective laser salivation (SLS), stereolithography (SLA) and three -dimensional (3D) printing (3DP). More common rapid prototyping processes include the production of laminated objects (quarries), modeling deposition (FDM) and melting electron beam (EBM). All these processes are automated and performed by machines that are controlled by computers by reading data from the prototype models using a computer supported design (CAD).

prototyping is the practice of creating models of new products or revisions of existing products before final approval and production in full scale. This process allows designers and developers to assess their proposals, identify errors or omission and demonstrate the Concept for all participating STearly. Of course, prototyping is a critical part of each design process, often returning considerable saving time and budget. Fast prototyping is one of the most popular methods used to construct prototype models. The process is additive, which means that the machines used add material to the model because the building proceeds unlike subtractive processes that cut off the material from the empty block.

There are several different techniques of rapid prototyping in general use used by metals, thermoplasts and photopolymers to gradually create the prototype, layers on the layer, from zero. One of the most popular of them is selective laser salivation (SLS), which uses carbon dioxide laser to fusion of plastic, ceramics or glass powder into the finished model. Laser runs in a pattern that precisely mimics the CAD model stored in the Connroller machine, a change of powder on a solid body as it isgoes. Direct Metal Laser Sintering (DMLS) is a similar process that uses metal powders.

Another commonly used process of rapid prototyping, which works in a similar way, is stereolithography. This process uses the ultraviole (UV) laser, which moves the tank of photopolymer resin formulated for treatment or hardened when exposed to UV light. As the laser follows the shape stored in the CAD file, the resin solidifies and gradually creates a prototype model. One of the most important recent developments in rapid prototyping is the three -dimensional (3D) printing process, which includes an inkjet type printer that puts the powder resin and binder layers to create the desired shape. There are also several other processes used in rapid prototyping, which, although they have fine process differences, share the same progressive technique of building an additive model.
