Aiming at the expensive price of ZCAST powder produced from Z-corp

we have developed a mixed powder of plaster with 400 meshes and Al2O3 powder with 200 meshes whose mass ratio is four via six. The gear mould was printed successfully based on the self-developed mixed powder through rapid prototyping machine. The aluminum alloy gear was produced successfully with the baked and solidified mould by following the processing procedure of ZCAST technology

decreasing 50% cost of rapid prototyping materials.
