Download - Sand Casting using 3D Printing
Metal Casting
Using 3D Printing Technology
The Idea
• I wanted to create a casting using 3D printing of sand cores but also….
• The shape had to be very difficult to produce by conventional core making processes
• This presentation shows the process used to create the sculpture
A complex shape, very difficult to make in metal by conventional (sand casting) means
Many undercuts in different directions
After the design is done… (3D ProEngineer)
..we add features for metal flow and to allow the gas to escape
Cores are designed to allow easy preparation
Base core
Middle core
Upper core with metal in-gate and gas outlets
Lower core with locating features
Middle Core with locating features
Upper core with locating features
Cores are printed by www.hoosierpattern.com
Cores are removed from machine
Loose sand removal
Upper core with locating features
Middle core with locating features
Core assembly
Lower and middle cores
Core assembly
Pour metal and clean the casting
Remove excess metal and polish
