Rapid Prototyping\u00c2\u00a0is a group of techniques used to quickly fabricate a\u00c2\u00a0scale model\u00c2\u00a0of a physical part or assembly using\u00c2\u00a0three-dimensional\u00c2\u00a0computer aided design\u00c2\u00a0(CAD) data.\u00c2\u00a0Construction of the part or assembly is usually done using\u00c2\u00a03D printing\u00c2\u00a0or “additive layer manufacturing” technology.<\/p>\n
Three-dimensional space\u00c2\u00a0(also:\u00c2\u00a03-space\u00c2\u00a0or, rarely,\u00c2\u00a0tri-dimensional space) is a geometric setting in which three values (called\u00c2\u00a0parameters) are required to determine the position of an element (i.e.,\u00c2\u00a0point). This is the informal meaning of the term\u00c2\u00a0dimension.<\/p>\n
In\u00c2\u00a0physics\u00c2\u00a0and\u00c2\u00a0mathematics, a\u00c2\u00a0sequence\u00c2\u00a0of\u00c2\u00a0n<\/span>\u00c2\u00a0numbers\u00c2\u00a0can be understood as a location in\u00c2\u00a0n<\/span>-dimensional space. When\u00c2\u00a0n\u00c2\u00a0= 3<\/span>, the set of all such locations is called\u00c2\u00a0<\/span>three-dimensional\u00c2\u00a0Euclidean space\u00c2\u00a0(or simply Euclidean space when the context is clear). It is commonly represented by the symbol\u00c2\u00a0\u00e2\u201e\u009d3<\/sup><\/span>.This serves as a three-parameter model of the physical\u00c2\u00a0universe\u00c2\u00a0(that is, the spatial part, without considering time), in which all known\u00c2\u00a0matter\u00c2\u00a0exists. While this space remains the most compelling and useful way to model the world as it is experienced,\u00c2\u00a0it is only one example of a large variety of spaces in three dimensions called\u00c2\u00a03-manifolds. In this classical example, when the three values refer to measurements in different directions (coordinates), any three directions can be chosen, provided that\u00c2\u00a0vectors\u00c2\u00a0in these directions do not all lie in the same\u00c2\u00a02-space\u00c2\u00a0(plane). Furthermore, in this case, these three values can be labeled by any combination of three chosen from the terms\u00c2\u00a0width,\u00c2\u00a0height,\u00c2\u00a0depth, and\u00c2\u00a0length.<\/p>\n A\u00c2\u00a0scale model\u00c2\u00a0is most generally a physical representation of an\u00c2\u00a0object\u00c2\u00a0that maintains accurate relationships between all important aspects of the\u00c2\u00a0model, although\u00c2\u00a0absolute values\u00c2\u00a0of the original properties need not be preserved. This enables it to demonstrate some behavior or property of the original object without examining the original object itself. The most familiar scale models represent the physical appearance of an object in miniature, but there are many other kinds.<\/p>\n Scale models are used in many fields including\u00c2\u00a0engineering,\u00c2\u00a0architecture,\u00c2\u00a0filmmaking,\u00c2\u00a0military command, salesmanship, and hobby\u00c2\u00a0model building. While each field may use a scale model for a different purpose, all scale models are based on the same principles and must meet the same general requirements to be functional. The detail requirements vary depending on the needs of the modeler.<\/p>\n To be a\u00c2\u00a0true\u00c2\u00a0scale model, all relevant aspects must be accurately modeled, such as material properties, so the model’s interaction with the outside world is reliably related to the original object’s interaction with the real world.<\/p>\n The first methods for rapid prototyping became available in the late 1980s and were used to produce\u00c2\u00a0models\u00c2\u00a0and\u00c2\u00a0prototype\u00c2\u00a0parts. Today, they are used for a wide range of applications, and are used to\u00c2\u00a0manufacture\u00c2\u00a0production-quality parts in relatively small numbers if desired without the typical unfavorable short-run economics.\u00c2\u00a0This economy has encouraged online service bureaus. Historical surveys of RP technology\u00c2\u00a0start with discussions of\u00c2\u00a0simulacra\u00c2\u00a0production techniques used by 19th-century sculptors. Some modern\u00c2\u00a0sculptors\u00c2\u00a0use the progeny technology to produce\u00c2\u00a0exhibitions\u00c2\u00a0and various objects.\u00c2\u00a0The ability to reproduce designs from a dataset has given rise to issues of rights, as it is now possible to interpolate volumetric data from one-dimensional images.<\/p>\n As with\u00c2\u00a0CNC\u00c2\u00a0subtractive methods, the computer-aided-design \u00e2\u20ac\u201c computer-aided manufacturing\u00c2\u00a0CAD\u00c2\u00a0-CAM\u00c2\u00a0workflow in the traditional rapid prototyping process starts with the creation of geometric data, either as a 3D solid using a CAD workstation, or 2D slices using a scanning device. For rapid prototyping this data must represent a valid geometric model; namely, one whose boundary surfaces enclose a finite volume, contain no holes exposing the interior, and do not fold back on themselves.\u00c2\u00a0In other words, the object must have an “inside”. The model is valid if for each point in 3D space the computer can determine uniquely whether that point lies inside, on, or outside the boundary surface of the model. CAD post-processors will approximate the application vendors’ internal CAD geometric forms (e.g., B-splines) with a simplified mathematical form, which in turn is expressed in a specified data format which is a common feature in\u00c2\u00a0additive manufacturing:\u00c2\u00a0STL\u00c2\u00a0file format, a\u00c2\u00a0de facto standard\u00c2\u00a0for transferring solid geometric models to SFF machines.<\/p>\n To obtain the necessary motion control trajectories to drive the actual SFF, rapid prototyping,\u00c2\u00a03D printing\u00c2\u00a0or\u00c2\u00a0additive manufacturing mechanism, the prepared geometric model is typically sliced into layers, and the slices are scanned into lines (producing a “2D drawing” used to generate trajectory as in\u00c2\u00a0CNC’s toolpath), mimicking in reverse the layer-to-layer physical building process.<\/p>\n 3D production systems\u00c2\u00a0allow\u00c2\u00a0electric cars\u00c2\u00a0to be built and tested in one year.\u00c2\u00a0Rapid prototyping is also commonly applied in software engineering to try out new business models and application architectures such as Aerospace, Automotive, Product development and Healthcare.<\/p>\n The above is a brief about Rapid Prototyping.
