was used for the modification of bisphenol A epoxy acrylate. We studied the effect of the mass fraction of the modified nano-Al

(1 % (wt) ~5%(wt))on the properties of the resin. The results showed that the smallest volume shrinkage rate was 6. 48% when the connection of modified nano-Al

was 5 % ( wt) ; the highest gelling percent was 88. 3 % when the mass fraction of modified nano-Al

was 2 %. TGA test results showed that nano-Al

improves the thermal stability of the resin. Tensile results showed that with the increase of the mass fraction of the modified nano-Al

the tensile strength of the composite first increased and then decreased
and the tensile strength was the highest when the mass fraction of modified nano-Al

was 3%(the tensile strength was 34. 74MPa and increased by 108. 27%). The originality of this paper is that
first
we used modifier KH570 to modify the surface of nano-Al

making it easier to disperse in the resin matrix. Second
this modified photosensitive resin is suitable for 3D printing environment.
