The market economy unceasing development, urges the industry product more and more to the multi varieties, high grade, the low cost direction to develop, in order to maintain and strengthens the product in market petitive power, product development cycle, production cycle more and more short, thereupon to makes each kind of product the essential craft equipment mold request to be more and more harsh. On the one hand the enterprise for the pursue scale benefit, causes the mold to turn towards high speed, is precise, the long life direction develops。 On the other hand enterprise in order to satisfy the multi varieties, the product renewal quickly, wins the market the need, requests the mold to turn towards the manufacture cycle to be short, the cost low fast economy direction develops. The puter, the laser, electronic, the new material, the new technical development, causes the fast economical pattern making technology even more powerful, the application scope expands unceasingly, the type increases unceasingly, the creation economic efficiency and the social efficiency are more and more remarkable. 2 fast economical pattern makings technologies type The fast economical pattern making technology and the traditional machinefinishing pares, has the pattern making cycle short, the cost is low, the precision and the life can satisfy in the production the operation requirements, is synthesizes an economic efficiency quite remarkable kind to make the mold the technology, summarizes below, has several types to leave. 附 錄 fast prototypes manufactures technology The fast prototype manufacture technology is called RPM, is one kind of new manufacture technology which the 8039。s later period develops. US, Japan, England, Israel, Germany, China have all promoted own mercialization product, and has formed the new industry gradually. RPM is the puter, the laser, the optical scanning, the advanced new material, the puteraided design (CAD), the puter assistance processing (CAM), the numerical control (CNC) synthesizes the application the high technology and new technology. In takes shape in the concept take the plane separate, piles up as the instruction, in the control take the puter and the numerical control as the foundation, take biggest flexibility as general goals. It has abandoned the traditional machinefinishing method, to the manufacturing industry transformation is a significant breakthrough, uses the RPM technology to be possible directly or indirectly the fast pattern making, this technology already by profession widespread application and so on automobile, aviation, electrical appliances, ships, medical service, mold. Under summarized already mercialization several kind of models fast to take shape at present the craft. lasers threedimensional photoetching technology (SLA) The SLA technology hands over the puter CAD modelling system to obtain the product the threedimensional model, through the microputer control laser, according to the determination path, is carrying on to the liquid state photosensitive resin by the level scanning, causes layer upon layer to solidify by the scanned sector, is united as one body, forms the final three dimensional entity, after again passes through the related finally hardening to polish and so on place the quantity, forms the workpiece or the mold. The laser threedimensional photoetching technology main characteristic is may take shape wilfully the plex shape, takes shape the precision high, simulation strong, material use factor high, performance reliable, the performance price quite is high. Suits the product outlook to appraise, the function experiment, fast makes the electrode and each kind of fast economical mold. But this technology uses equipment and photosensitive resin price expensive, causes its cost to be high. pack of levels outlines manufacture technology (LOM) The LOM technology is through the puter threedimensional model, the use laser selectively to its lamination slice, will obtain each section outline layer upon layer will cake, finally will fold the addition three dimensional entity product. Its craft characteristic is takes shape the speed quickly, takes shape the material small advantage, the cost lowly, because does not have changes, therefore does not have the thermal load, the contraction, the inflation, the warp and so on, therefore the shape is
