In only 50 seconds, the CIR Sand Casting System allows for the replication of a residual limb. This model can then be modified and used to create a final transtibial (below-the-knee) prosthetic socket. The technique eliminates the need for plaster bandages and Plaster-of-Paris, and requires only:

1.A large container
2.Silica sand
3.An air compressor capable of maintaining a vacuum
4.A metal pipe for connecting to vacuum pump
5.Thin plastic bags
6.Rubber bands
