Abstract

A method for making three dimensional structures using photolithography and an adhesively bondable material is disclosed. A thiol-ene-epoxy (OSTE(−)) material undergoes a first reaction upon partial irradiation in a pattern to become a partially cross-linked polymer network. Non-cross-linked parts are dissolved in a solvent and removed. An initiator is added to activate the cross-linked polymer network so that it becomes adhesive and can then be covalently bound to another object to form an article. The method can be utilized to manufacture an article with a complicated three dimensional shape in an easy way.
