Methods, systems and formulations of building a three-dimensional object with a glossy surface, the method may include: selectively depositing a first material in a plurality of layers to form a body region of the three-dimensional object, wherein said first material comprises a multifunctional acrylic monomer; selectively depositing a second material in a plurality of layers to form a support region, wherein said second material comprises a monofunctional hydrophilic acrylic monomer and does not comprise a multifunctional acrylic monomer; curing each of the deposited layers, wherein in at least one of the deposited layers the first material and the second material mix to form an intermediate region at their mutual interface; dissolving the support region in an aqueous solution; and drying the body region and the intermediate region, whereby the dried intermediate region provides a glossy surface on the body region of said three-dimensional object.
