Embodiments herein disclose a method for fabricating high aspect ratio structures. The method includes depositing a predefined quantity of a viscoelastic fluid on a top surface of a bottom cell plate and compressing the viscoelastic fluid deposited on the top surface of the bottom cell plate using a bottom surface of a top cell plate. The viscoelastic fluid is a blend of a solvent and a polymer. At least one of the top cell plate and bottom cell plate comprises a plurality of lands, sealed source holes and/or unsealed source hole for penetration of a low-viscous fluid. Further, the method includes separating the top cell plate and the bottom cell plate to induce out of plane stretching of the high viscous fluid and obtaining a plurality of high aspect ratio structures between the top cell plate and the bottom cell plate due to the penetration of the low-viscous fluid.
