Material Notes:
Polyphenylsulfone (PPSF) is an incredibly durable high-end thermoplastic that can be used in your toughest applications. Parts built in PPSF can handle heat near 400?F (204?C), it resists petroleum products, acids, and bases, and its strength is superior to other rapid prototyping thermoplastics. PPSF parts are built with a layered manufacturing process utilizing Fused Deposition Modeling (FDM) technology. This technology can build parts with high-performance engineering materials ideal for functional prototypes and end-use parts.

Applications: Based on its high-performance properties of heat and chemical resistance, PPSF is ideal for engine components, covers and enclosures subject to heat, industrial machinery components or any application where your part needs to be functionally tested in an environment of heat or chemicals. Parts build in PPSF are also used as masters for RTV molds and vacuum forming.

In a rapid manufacturing application, Polyphenylsulfone can be used to create actual production parts in lieu of injection molding for short-run production. Rapid (or layered) manufacturing provides multiple benefits:

• High design iterations ? while in production the design engineer has the freedom to modify geometry?s on the fly which cannot be done once you have committed to tooling
• Bridge manufacturing ? with rapid manufactured parts, production can begin while permanent tooling is on order
• Jigs and Fixtures to be used on manufacturing/production lines
• For those manufacturers who practice lean manufacturing techniques or who maintain just-in-time inventories, RM can conserve cash flow
• Alpha and beta product releases ? manufacturers can produce accurate, durable products even in the earliest stages of production
