Utjecaj procesnih parametara na silu kidanja dijelova proizvedenih procesom selektivnog laserskog sinteriranja

Insufficient knowledge about essence of the Selective Laser Sintering - SLS process and influence of process parameters on properties of produced parts constraints widely usage of SLS process in production systems. One of the most significant process failures is impossibility of full-real load of the produced parts-prototypes. Influence on process parameters is analysed in this paper (laser power and scan velocity), as well as post processing influence on value of axial breaking force of the parts produced by SLS process using material DM50-V2, on machine EOSIMT M250, producer EOS Münich, Germany.Nedovoljno poznavanje suštine procesa selektivnog laserskog sinteriranja - SLS, te utjecaja procesnih parametara na osobine proizvodenih dijelova u značajnoj mjeri ograničava širu primjenu SLS procesa u proizvodnim sustavima. Jedan od zanačajnijih nedostataka ovoga procesa je nemogućnost vršenja potpunog - realnog opterećenja proizvedenih dijelova - prototipova. U radu je izvršena analiziran utjecaja procesnih parametara (snage lasera i brzine skeniranja), te procesa postprocesuiranja na vrijednost aksijalne sile kidanja dijelova proizvedenih SLS procesom od materijala DM50-V2, na stroju EOSIMT M250, proizvođača EOS Münich, Njemačka

MOLDS FOR CASTING VEHICLE PARTS

Abstract Casting metals and alloys makes most of the parts for vehicles. To shorten the time to market and get a satisfied quality new design approach have to be involved. New CAD based technologies are giving an opportunity to make molds faster and cheaper with a high quality than previously using classical methods. In this paper master mold design process including decision about materials is presented. All principals for rapid tooling molds are applied at the mold for iron casting part for trains
