The invention relates to a preparation method of 3D-printing super porous elastic graphene aerogel. The method includes the following steps that (a), graphene oxide, ascorbic acid and deionized waterare mixed to form graphene hydrogel ink; (b), microporous graphene hydrogel ink is obtained through heating; (c), the microporous graphene hydrogel ink is transferred into a 3D printer; (d), 3D graphene oxide hydrogel is subjected to freeze-drying, then heating is conducted to make graphene oxide and ascorbic acid react, the obtained reaction product is soaked in deionized water overnight so as toremove soluble impurities, and then freeze-drying is conducted to obtain reduced graphene oxide aerogel; (e), the reduced graphene oxide aerogel is subjected to high-temperature calcination under theinert gas condition. In this way, the 3D-printing graphene aerogel low in density and excellent in elasticity, fatigue resistance and compression resistance can be obtained.
