    Abstract: The invention relates to a process of processing a radiation-curable composition with an additive-manufacturing technique comprising a radiation-curing step, the radiation-curable composition comprising mercapto-functional Component A comprising at least three mercapto moieties, crosslinker Component B with at least three vinyl or allyl moieties, photo-initiator(s) Component C for initiating a curing reaction between Component A and Component B, wherein the radiation-curable composition does not comprise urethane (meth)acrylate oligomers in an amount of more than 4 wt.% with respect to the whole composition. 3-dim articles which can be produced are typically transparent and have adequate mechanical properties. The radiation-curable composition is in particular useful for producing clear-tray aligners for dental and orthodontic purposes.

    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.
