Today, if you break a bone such as your arm, your doctor will most likely have you wear a plaster cast. Doctors around the world use plaster casts because of their durability, however that are not without their faults. This cast is be heavy, uncomfortable, and not waterproof so simple tasks such as showering become difficult and tedious. I have an idea to use 3D printing to create a lighter, more comfortable cast with the same durability as the plaster. This new version will lead to an overall more comfortable and easier healing process.
