Is concerned, the development level of the Rapid prototyping technology in China is mainly applied to the development of new products (including the upgrading of products) of the design verification and simulation of the sample preparation, namely from the concept of product design or retrofit design, modelling design, structure design, basic function assessment, simulation trial samples during this development process.
The application of rapid prototyping is mainly reflected in the following aspects:
(1) design verification and functional verification in the process of new product development.Rapid prototyping technology can quickly convert the CAD model of product design into the physical physical model, which can easily verify the designer’s design ideas and the rationality of the product structure, assembly, beauty, found in the design of the problem can be modified in time.
(2) manufacturability, assemblability test and supply inquiry, market publicity, the test and design of the manufacturability and assemblability of complex systems with limited space, such as automobiles, satellites and missiles by Rapid prototyping technology, will greatly reduce the design and manufacturing difficulty of such systems.For complex parts that are difficult to determine, Rapid prototyping technology can be used for trial production to determine the best reasonable process.Moreover, Rapid prototyping technology is an effective means of communicating products from design to commoditisation.Rapid prototyping (rp) technology has become a technical approach to concurrent engineering and agile manufacturing, such as providing customers with product samples and marketing.
(3) direct production of single, small batch and special complex parts.For polymer parts, high strength engineering plastics can be directly rapid prototyping, to meet the use of requirements;For complex metal parts, they can be obtained by rapid casting or direct metal forming.The application has special significance for the aerospace and defense industries.
(4) rapid mold manufacturing.Through various conversion technologies, the RP prototype is converted into various rapid molds, such as low-melting alloy mold, silica gel mold, metal cold spray mold, ceramic mold, etc., for the production of small and medium-sized batch parts, to meet the rapid replacement of products, the development trend of smaller and smaller batch.The field of rapid prototyping application includes almost every industry in the manufacturing field, and it has been applied more and more widely in medical treatment, human body engineering, cultural relic protection and other industries.
The main applications of rapid prototyping technology are as follows:
◆ automobile and motorcycle: design, modification and assembly test of appearance and interior decoration, trial production of engine and cylinder head.
Home appliances: design the shape and structure of various home appliances, test assembly and function verification, market publicity, mold manufacturing.
Communication products: product shape and structure design, assembly test, function verification, mold manufacturing.
◆ aviation and aerospace: direct manufacture of special parts, trial manufacture of impeller, turbine and blade, trial manufacture and assembly test of engine.
