Vertical Centrifugal Investment-Casting Machine

The need for improved investment castings at Marshall Space Flight Center's Rapid Prototyping Lab has led to the development of a simple machine for centrifugal investment casting of shells. This machine spins a radially symmetric shell about its own axis in a vertical orientation. This rotational process increases the strength of the investment casting by allowing the metal to move into even the most obscure crevices of the shell.
