Method for making three dimensional structures using photolithography and an adhesively bondable material

A method for manufacturing an article comprising the steps of:

• a) providing a material which is solid at room temperature, wherein said material is soluble in an organic solvent, wherein the material comprises at least one selected from the group consisting of i) an epoxy resin with unsaturated carbon-carbon bonds and ii) an epoxy resin with a molecular weight over 400, wherein the material comprises monomers comprising at least two thiol groups, monomers comprising at least two carbon-carbon unsaturated bonds, and a first initiator capable of initiating a chemical reaction to form a cross-linked polymer network when the material is exposed to actinic radiation in a first activation step and wherein said material can undergo the chemical reaction to form a cross-linked polymer network when the material is exposed to actinic radiation in the first activation step,
• b) at least partially exposing said material to actinic radiation adapted to initiate the chemical reaction to form a cross-linked polymer network in the first activation step, wherein said exposure is made in a pattern, wherein the cross-linked polymer network is not soluble in the organic solvent,
• c) dissolving non-cross-linked portions of said material in an organic solvent so that the cross-linked polymer network remains,
• d) contacting the cross-linked polymer network with an object including chemical groups that act as a second initiator in a second activation step to initiate a further reaction to create further cross links and adhesive properties in the cross-linked polymer network and obtain an activated cross-linked polymer network which bonds to the object to form the article.
