HexAM® Additive Manufacturing Title Subtitle and Aftermarket Applications Hexcel’s HexAM® additive manufacturing process combines high-performance thermoplastic with selective laser sintering (SLS) technology to produce fully functional HexPEKK® end-use components. HexPEKK® parts offer significant weight, cost and time-to-market reductions compared to incumbent metal or composite technologies while providing repeatable and validated engineering material properties. Superior Material Superior Process ¥¥Assembly consolidation, multiple components sintered as a single piece ¥¥Complexity of part geometry does not affect cost ¥¥SLS (powder bed) process allows for large quantity of components in a single chamber approximately 660mm x 356mm x 534mm Benefits ¥¥HexAM® additive manufacturing combines a high-performance PEKK thermoplastic with an aerospace-grade carbon fiber fill ¥¥Fully qualified through America Makes, AFRL, NASA, Northrop Grumman and Boeing ¥¥Excellent flammability, outgassing, smoke/toxicity performance ¥¥Service temperature: ±300˚F – appropriate metallic/composite replacement ¥¥600˚F melt temperature ¥¥Similar in specific strength to cast aluminum ¥¥Compatible with all common aerospace fluids ¥¥Density half of cast aluminum – excellent weight savings tooling required – lowers cost and lead time ¥¥No touch labor required – quicker process than conventional machining ¥¥Engineering changes do not require rework/redesign of tooling ¥¥Optimization potential – improved weight

Production solutions for aftermarket components HexAM® additive manufacturing is ideal for anything from low-rate customization parts to quick replacements of casting and composite ducts.
