The present disclosure provides a photo-curable elastic ink composition for three-dimensional printing and the preparation method. The ink composition includes approximately 10%-75% of a soft monomer, approximately 10%-75% of a hard monomer, approximately 5%-20% of a cross-linking agent, approximately 5%-20% of a non-reactive soft resin, approximately 0.5%-10% of a photo-initiator, approximately 0%-0.5% of a colorant, and approximately 0.05%-8% of an auxiliary agent. The soft monomer is capable of generating a homopolymer with a glass transition temperature lower than about 25&#xb0; C. The hard monomer is capable of generating a homopolymer with a glass transition temperature of about 25&#xb0; C. or higher. The non-reactive soft resin is a resin without containing any radiation curable group in the molecular structure and having a glass transition temperature less than 0&#xb0; C.

A method for fabricating a colored 3D object is provided. The method includes: forming, based on layer-structure data of a target object, a layer-structure product by printing of a molding material; forming a layer-print product by printing color inks on the layer-structure product based on layer-color data; and repeatedly forming the layer-print product to provide a plurality of the layer-print products, and fabricating a colored 3D object from the plurality of the layer-print products, stacked one over another. The color inks are printed synchronously or following the formation of the layer-structure product. A system for fabricating a colored 3D object includes a processing terminal, a print head, and a drive controller. The method and system improve a dimensional accuracy and printing efficiency of the colored 3D object.
