Material
SLS PEEK
SLS PEEK is a high-performance thermoplastic that offers high tensile strength, good heat resistance, and broad chemical resistance in a lightweight part, if with low ductility.
Manufacturing processes
About
SLS PEEK is a high-performance thermoplastic in the PEEK family, with tensile strength of 80–100 MPa, a density of about 1.2-1.3 g/cm³, and heat deflection of up to about 165 °C under load.
As printed, SLS PEEK parts exhibit a light tan to beige matte finish with the fine micro-granular texture characteristic of high-temperature sintering. The material's inherent stability ensures excellent dimensional accuracy, low creep, and reliable performance under continuous loads. It resists most solvents, fuels, and oils but not concentrated sulfuric or nitric acid or halogens, and it has poor UV resistance.
SLS PEEK is well suited to brackets, housings, and bushings that face heat, solvents, or fuels.
