237. Rapid Prototyping Introduction
Rapid Prototyping: it combines the numerical control technology, CAD technology, laser technology, materials science and technology, automatic control technology and other advanced achievements of the discipline, the use of light, heat and other energy forms, materials, sintering, curing, bonding or melting eventually forming a part of the three-dimensional physical model. Laser sintering depth: a direct impact on the quality of sintering an important factor, the appropriate sintering sintering depth of good quality premises, shop powder sintering depth must be greater than the thickness, to ensure that laser energy can be dissolved through the current layer, Shi Xiang o produce two sintering, otherwise you will have layered lead to deterioration of the precision molding strength, not even formed, so the factors affecting the sintering depth study, through the rational selection of process parameters to control the sintering depth is of great significance. Sintering depth mainly by the laser energy parameters and powder characteristics of the material parameters. Which the laser energy parameters also includes laser power laser beam, scanning speed, laser wiring harness, length and width; powder material parameters include powder material on the laser absorption rate, powder melting heat capacity, particle size and distribution, particle morphology and Shop powder density. Forming precision: the precision of the workpiece is formed, rather than the machine precision rapid prototyping machine, is to ensure that an important prerequisite for the accuracy of molded parts, including the shape forming precision accuracy, dimensional accuracy and surface accuracy, the sintering parts in the shape and size and surface three indicators of each location and design meet the requirements of the degree. Direct / indirect rapid tooling; direct rapid tooling is made using SLS, FDM, LOM between the methods such as rapid prototyping technology to create a resin mold, ceramic mold and metal molds. Indirect rapid tooling for rapid prototyping refers to the mother or the over-mold parts, and through the mold of traditional manufacturing methods to produce each mold. Soft-mode technology; using a variety of rapid prototyping technology, including SLS, FDM, LOM directly to CAD model (virtual model) to a certain mechanical properties of metallic prototypes (physical prototypes), in many cases can be used as a soft mold for the production of small quantities of plastic parts. Bridge mode technology; is epoxy composite materials with organic or inorganic materials as the base to the prototype as the base of a burning indirectly pouring mold molding method. Cover mold ceramic powder: It is by mixing grains - squeezed - ball crushing obtained, the bulk of the organic resin mixed with ceramic powder by ball milling for irregular crushed shape, particle size from a few tenths of microns to tens of microns, large particles of organic resins and ceramics by a large number of particles of the aggregate basic (aggregate).
