Hexcel has launched an electrically-conductive high-performance thermoplastic for 3D printing using selective laser sintering (SLS). Applications in  EMC shielding, static dissipation and radar absorption are foreseen. Called HexPEKK EM, it is a polyetherketoneketone (PEKK) and carbon fibre composite for flight-ready parts in commercial aerospace, defence and military sectors. Surface resistivity is ~8×104Ω/sq and volume resistivity ~4×103Ωcm. ...
