ABS is a low cost engineering plastic that is easy to machine and fabricate. ABS is an ideal mate rial for structural applications when impact resistance, strength, and stiffness are required. It is widely used for machining pre-production prototypes since it has excel lent dimensional stability and is easy to paint and glue. ABS is easily machined. Common machining techniques include turning, drilling, milling, sawing, die-cutting and shearing. ABS can be cut with standard shop tools and line bent with standard heat strips. ABS can be chemically affixed to itself and other like-plastics.
Polycarbonate (CNC) - PC - has excellent impact strength and good temperature resistance. Suitable for outdoor applications. Can be colored or transparent.
Nylon 6/6 is the most commonly used of the Nylon family of plastics. It enjoys relatively high chemical and heat resistance, and is stiff enough to retain its shape, but tough enough not to permanently deform under load. Two of the most notable use cases for Nylon are in medical devices and electronics insulation, notably screws and spacers for panel mounted circuit boards.
