What is the model of a quick prototype?
A rapid prototype model is usually a plastic or metal part created from a computer drawing that allows the customer to check the development product. Starting at the end of the twentieth century, computer software was developed to allow designers to create three -dimensional (3D) drawings. The parallel development of a device that could create physical structures from these drawings led to the business of fast modeling.
The design of the part using 3D software begins with a conceptual drawing of the required part. The designer can take this drawing and create a software 3D model that allows the part to be seen from different angles or orientations. This software can also practically analyze part to show the customer how to install in the industrial plant. Software design often involves the ability to "test" part under different conditions of stress or impact on the estimation of component failure or design deficiencies.
The development of a fast prototype model has become a reality with the introduction of 3D printers. Several different technologiesIt developed at the end of the twentieth century, but all were associated with computer -supported design programs (CAD) that created software models. All 3D printers use the technique of creating consecutive plastic or metal layers to create a physical sample of part.
One type of printer used a fine powder inside the printer cabinet. Computer software has changed the drawing on thousands of extremely fine layers, such as cutting the image extremely thin. The printer sprayed the chemical binder for the lowest layer -shaped powder. The powder was then mixed to this layer and the flat tray reduced a small amount. Another layer of binder and powder was added, and so on until 3D was made. Depending on the complexity of the part, the printer might need to run for days to complete one sample.
Other types of the fast prototype model The printer used extensible plastic. NozzleILA small dots of molten material on the printer tank in consecutive layers to form part. These parts were often usable directly from the machine, as the plastic layers formed a solid plastic prototype. It was an improvement compared to some powder printers that created parts that could be handled but may not be strong enough for testing or actual use.
The process called metal slinting could also create a model of a quick prototype. Metal, such as aluminum or copper with a relatively low melting point, could be used in a 3D printer in a similar way to melted plastic. The finished metal part often did not require any further processing and could be used directly from the machine for testing or further development.
Many products in the 21st century were completely designed in CAD software, which made the virtual image with a rapid prototype of the model without the need to create a physical sample. This Became common to large industrial machines, aircraft and a large carIdles like ships. Many parts were too large to create separate prototypes or delayed the development of the final product.
engineers have developed software testing that could simulate the real testing conditions, eliminating the need for prototype tests. The first commercial aircraft was designed in this way at the end of the 20th century. The commercial aircraft was built exclusively on the computer and moved from the design directly to the aircraft capable of flight without intermediate prototypes.
