Zusammenfassung:	A selective laser sintering composition and a selective laser sintering 3D printing method employing the same are provided. The selective laser sintering composition includes a nanoscale inorganic powder and a thermoplastic vulcanizate powder. The temperature difference (ΔT) between the onset temperature for melting the thermoplastic vulcanizate powder and the onset temperature at which the thermoplastic crystallizes vulcanizate powder is greater than or equal to 10° C. The thermoplastic vulcanizate powder includes a thermoplastic and a crosslinked polymer. The temperature difference (ΔT) between the onset temperature for melting the thermoplastic and the onset temperature at which the thermoplastic crystallizes is greater than or equal to 10° C. , and the weight ratio of the thermoplastic to the crosslinked polymer is from 1:1 to 1:4.
