NOVELTY - Printing three-dimensional graphene airgel material involves using graphene and graphene oxide, which is dispersed in an aqueous solution, and then solution is gradually added into phenol-melamine-formaldehyde-furfural aand than mixed in system. The molar ratio of phenol-melamine-formaldehyde-furfural mixed system and potassium bisulfate, potassium bisulfate are 0.8:1:06:0.9:0.7 using ultrasonic vibration to form a uniform solution. USE - Method for printing three-dimensional graphene airgel material (claimed). ADVANTAGE - The method enables to print three-dimensional graphene airgel material is increasing forming performance and decrease deformation. DETAILED DESCRIPTION - Printing three-dimensional graphene airgel material involves using graphene and graphene oxide, which is dispersed in an aqueous solution, and then solution is gradually added into phenol-melamine-formaldehyde-furfural aand than mixed in system. The molar ratio of phenol-melamine-formaldehyde-furfural mixed system and potassium bisulfate, potassium bisulfate are 0.8:1:06:0.9:0.7 using ultrasonic vibration to form a uniform solution. The forming uniform solution, and then ultrasonic vibration mass ratio of collagen, collagen graphene is 1:5 to 1:30, and then heated at temperature of 50-60 degrees C for 70-90 minutes, to obtain a hydrogel. The use of autoCAD software to design shape of parts required for model structure and are intended for enclosed cavity. The complex lumen part model, be slicing process,where layer thickness is 0.02-0.20mm, to obtain a three-dimensional model data components. The three-dimensional model data slice part after introduction memory three-dimensional printing apparatus, and then obtained product is injected into hydrogel three-dimensional printing apparatus. The mixing of hydrogel material through these nozzles three-dimensional printing apparatus three-dimensional model layer by layer printing data, where each of thickness is not exceeding 0.20mm. The layers are separated, organic monomer slurry printing three-dimensional network is formed by chemical crosslinking polymer gel, which is quickly solidified layer by layer accumulating body. The obtained product is placed in a vacuum drying process to obtain final product.
