Rapid Prototyping Machine: The Basic Things To Pay Attention To
Automatic creation of real objects by means of layered building of the material with the help of rapid prototyping machines like stereo lithographic apparatus, three-dimensional printer or any other. Rapid prototyping technology is computer-aided, which means that it works only on the basis of intercommunication between prototyping machine and three-dimensional graphical program. The essence of rapid prototyping technology lies in the signal transferred by a computer to a rapid prototyping machine. Thus, the whole process is controlled automatically. Such idea was born in the mind of an American engineer in 1988 when it became obvious that manual prototyping was too old-fashioned and unprofitable to be used. This technology was immediately patented and is used until know. The process of model making was implemented by means of laser beam which finished the creation of the model. If in the past times carving and tooling were done manually, by means of specials tools cutting extra layers of materials from the model and shaping it, now the process requires no additional tooling. It means that the process of material growing is done the way, that finished model looks perfect. It is attained by means of computing. Let us look through the process of model-making more thoroughly. To create a rapid prototyping object you have to buy or to download from the corresponding web site a CAD file. It is an image of the object, which you need to copy. Special 3D graphical program creates a virtual image of the object. By adding an electronic web to the image you get segments called cross-sections. Those are small squares of an image that can be move in any direction if needed to get a perfect result. In the course of prototyping process, 3D program cuts off layers of the image. A prototyping machined ‘understands’ this process inversely and builds up cross-sections by means of material. The more layers are cut off the image the more layers are build by a machine. The size and thickness of material are calculated numerically, in order to get the needed result. After the entire image is cut down, the ideal copy of initial object and of the image is done. Manual assistance is needed to program the computer only. Comparing to the previous prototyping process done manually, electronic prototyping is a great step forward in rapid prototyping. Prototyping modeling was not so popular in the past times mostly due to the high price of this technology. It was unprofitable to test objects that were to be produced by means of this technology, because the cost price of such product was senseless, as it had to be considered in the course of actual production. It reduced the number of clients using the services of this technology, because they couldn’t pay for this. Nowadays, it is hard to imagine the pre-production testing without rapid prototyping and it is the greatest achievement of the rapid prototyping technology.
