Rapid Prototyping: General Aspects
The second half of the 20th century was the time when computer technologies appeared bringing the new era of high technologies with. Nowadays it is hard to imagine any sphere of life without computers. They have already become an inalienable part of our lives. Many things that seemed to be a fantasy in the second part of the previous century came true. Among them are space exploration and space flights, launching of satellites and flight to the Moon, ocean floor monitoring and deciphering of the ancient letters. Of course, those are just a few examples of computer application, but they are one of the most important for us, while they help to get to know the history and life of our ancestors. Computers are also applied in different industries, like machine engineering, production of technical appliances, etc. Any company and corporation cannot do without computers as all important financial data is stored in computers. Any failure in work of computer network in such big corporations is capable of breaking the work of an enterprise. Rapid prototyping, mostly popular as solid free form fabrication and layered technology, is not an exception and also depends on computers, its work would be simply impossible without these machines. The name of the technique, which is the part of rapid prototyping technology is computer aided design or CAD. This abbreviation is used more often to denote the process. The essence of this technique lies in the intercommunication between a prototyping machine and a computer that controls the whole process of rapid prototyping model production. The electronic prototype of the future model (it can be any real object) is created by designers with the help of a special three-dimensional graphical programs. Electronic model looks like a net of small segments, which can be parted by a special tool of the program. Segments can be moved the way designers need. This technique is called cross-sectioning and the segments, correspondingly, are called cross-sections. In the process of rapid prototyping a computer cuts off the layers, or cross-sections of a model and a prototyping machine fulfils the vice versa process – it builds up the layers of prototyping material until the whole object that was virtually created by a 3D program is done. No additional carving or shaping is needed while due to the peculiarities of a prototyping process the model has a perfect shape, the same as created by a computer.
Technical development and constant improvement of the prototyping process will sooner or later lead to the appearance of diminutive prototyping machines that can be used at home by anyone. The day is coming when any lacking part of any technical appliance or even nails can be produced in several minutes. Who know which innovations are waiting for us in the nearest future?
Over the recent decades rapid prototype services managed with solving lots of tech problems. And rapid prototype might help you to. Please make sure to read more about the rapid prototype technology and how it helps.
