Sažetak
Application of prototypes becomes more and more important in product development process. The reason lies in development of number of automatic processes of Rapid Prototyping (RP) which enables direct prototype production based on CAD model of product within few hours or days. One of the basic disadvantages of RP processes is still limited number of applicable material for prototype production. On the other hand, if there exists appropriate material for prototype production, physics of prototype production is different than of for e.g. injection moulding. This leads to key differences in properties of prototypes and future products produced by injection moulding. Another trend on the market could be noticed - demands for production of larger amount of the same prototypes. In that case, RP processes are not so attractive because of the costs of prototype materials and the speed of RP process in comparison with e.g. injection moulding. Such state causes application of RP processes as processes for production of elements or whole moulds - Rapid Tooling processes (RT). Different properties of materials for RT mould inserts than traditional mould materials could be main disadvantage of such processes. Therefore it is necessary to analyse diferences in moulding properties caused by application of RT mould inserts. In this study an RT mould inserts are produced with Indirect Metal Laser Sintering process. Material for RT inserts was Laser Tool A6, and for classical inserts 1.2312. Injection moulding was performed with both inserts and properties of moulding was compared. Mouldings produced in classical mould showed higher dimensional stability as well as higher impact strength.
