	Rapid prototyping - Wikipedia, the free encyclopedia
		Rapid prototyping, is the automatic construction of physical objects using solid freeform fabrication.
		The first techniques for rapid prototyping became available in the 1980s and were used to produce models and prototype parts.
		Rapid prototyping takes virtual designs (from computer aided design (CAD) or from animation modeling software), transforms them into cross sections, still virtual, and then creates each cross section in physical space, one after the next until the model is finished.

	Connect: Information Technology at NYU
		Rapid prototyping does not represent a break with the tradition of cyclical design by incremental improvement or successive approximation; rather, it speeds the design cycle and increases the use of prototypes to an extent that new ideas, new results, and new techniques become possible.
		Rapid prototyping in a sense marries these two technologies by allowing designers to create plans for real world objects in the virtual world of the computer, and then in a single step to create a physical object directly from those plans.
		Rapid prototyping, on the other hand, is an additive process: the desired object is built from bottom to top in very thin layers.

	Rapid Prototyping
		The prototype gives the designer a functional working model of their design so they can work with the design and identify some of its possible pros and cons before it is actually produced.
		Prototyping can be used to gain a better understanding of the kind of product required in the early stages of system development where several different sketch designs can be presented to users and to members of the development team for critique.
		Prototyping can help to establish the suitability of the interface at the task level once the requirements for a system have been determined and its functionality is defined.

	Rapid Prototyping: Printable Version
		Rapid prototyping is important to this process because designers go back and forth between the concrete and the abstract.
		Rapid prototyping may be done for just one component of a larger product; it is not necessary to prototype an entire product.
		Coded prototypes are more realistic, but there are substantial drawbacks, such as the time needed to affect changes, the tendency of testers to focus on trivial attributes, developer resistance to change, and the risk that a single bug will halt the testing process entirely.

	Rapid Control Prototyping
		Rapid Control Prototyping or RCP is a process which lets the engineer quickly test and iterate their control strategies on a real-time computer with real input/output devices.
		Rapid control prototyping differs from HIL in that the control strategy is simulated in real-time and the “plant,” or system under control, is real.
		Rapid control prototyping is now the typical method used by engineers to develop and test their control strategies.

	Prototyping - Wikipedia, the free encyclopedia
		Prototyping is the process of quickly putting together a working model (a prototype) in order to test various aspects of a design, illustrate ideas or features and gather early user feedback.
		Prototyping is often treated as an integral part of the system design process, where it is believed to reduce project risk and cost.
		Prototypes are mock-ups of the screens of an application which allow users to visualize the application that is not yet constructed.

	Rapid Prototyping Glossary
		Generally refers to tooling which is made directly by a rapid prototyping system, as opposed to using the RP part as a pattern in a secondary process.
		A secondary operation in which parts formed by a rapid prototyping method are brought to acceptable final finishes and tolerances typically by subtractive CNC technology.
		Rapid tooling may utilize direct or indirect methods: In direct methods, the part fabricated by the RP machine itself is used as the tool.

	UsabilityNet: Rapid prototyping methods
		In rapid prototyping interactive prototypes are developed which can be quickly replaced or changed in line with design feedback.
		If the prototype is to be evaluated with users then allow time to design relevant tasks, recruit the users, evaluate the prototype and report the results.
		Also, although rapid, the method can often be more time consuming than other approaches and that resources required are greater than paper and pens due to the need for software and hardware.

		Other additive rapid prototyping processes that the organisation has in-house also includes a Perfactory system from Envisiontec which forms the basis for their ‘Micro-Modelling' service.
		But as with all good rapid prototyping service providers, what really counts is the fact that they have the in-house staff with the knowledge to work with their customers, irrespective of pre-existing knowledge levels, to help in finding the most suitable methods to assist in developing products further and eventually bringing new products to market”.
