| Abstract: | In the paper the new energy source technology is researched that the gas lasers is replaced by the laser diodes(LD) in the laser rapid prototyping(RP) system, because some defects are existed in the existing RP system using gas lasers.The LD beam characteristics,the collimating and expanding technologies are studied.The power density and the scanning velocity of the LD focusing spot are calculated and analysed too.The new RP energy source using LD has some advantages,such as long life,high reliability,small... |
