Abstract

A foamable resin composition comprising: (meth)acrylate oligomer, which accounts for 10-40 wt % of the foamable resin composition; (meth)acrylate monomer, which accounts for 35-80 wt % of the foamable resin composition; a photocuring initiator, which accounts for 1-5 wt % of the foamable resin composition; and a foaming agent, which accounts for 3-20 wt % of the foamable resin composition; wherein the foamable resin composition has a specific gravity of 0.10-1.05 g/cm3 after photocuring and thermal foam expansion for 15-20 minutes at 120° C. The aforementioned foamable resin composition can become a low specific gravity (0.10-1.05 g/cm3) material after photocuring and thermal foam expansion, then can expand the application in 3D printing, and manufacture of plastic products, such as shoe soles, coasters, floats, various types of protective gear and the like.
