Abstract: The invention is directed to a process for producing a outsole or inner sole of a footwear comprising the following steps (a) providing a first form negative mould of the outsole or inner sole comprising of at least one formed plastic sheet as obtained by thermoforming using a first master mould corresponding with the shape of a first side of the outsole or inner sole, (b) adding a liquid curable composition to the first form negative mould, and (c) solidifying the curable composition wherein a solidified outsole or inner sole is obtained and wherein the first form negative mould is removed from the solidified outsole or inner sole.

Abstract: The invention is directed to a process for producing a cured 3D product comprising the following steps: (a) providing a form negative mould of the 3D product comprising of one or two formed plastic sheets as obtained by thermoforming corresponding with the shape of the 3D product; (b) adding a liquid curable composition to the mould such that the inner surface of the mould is covered by the curable composition; and (c) solidifying the curable composition wherein a solidified layer or body is formed having the shape of the 3D product; wherein the cured 3D product is a radiation cured 3D product; and wherein the step (c) a radiation curable composition is solidified by radiation through the plastic sheet of the mould to form a solidified layer having the shape of the 3D product.

Abstract: The invention is directed to a casting process to make a metal 3D product by performing the following steps, (a) providing a form negative mould of the 3D product comprising of a plastic sheet which sheet defines at its inner side a hollow space corresponding with at least the shape of one or more of the 3D products by thermoforming using a master mould, (b) applying a layer of refractory material on the exterior of the plastic sheet of the mould to obtain a ceramic mould having a hollow space, (c) pouring molten metal into the hollow space of the ceramic mould and allowing the metal to solidify, and. (d) removing the layer of refractory material to obtain the metal 3D product.
