Combining the SL with conventional investment casting, the casting pattern is made of photocurable resin instead of wax by SL process.The resin pattern is coated with slurry to form a ceramic shell.

• 本文的研究采用快速成型机LPS-600A快速制造光固化树脂原型，以此树脂原型代替熔模铸造中的蜡模直接作为精密铸造中的铸型来直接铸造出金属零件，此工艺过程不需复杂工装及模具，可大大提高制造速度，并降低制造成本。
