Method for producing an article by layer-by-layer buildup with separately patterned resin and initiator wherein the resin has a storage modulus greater than loss modulus at 20 C

A method for producing an article in which a layer with a radically cross-linkable resin is selectively crosslinked at least partially. This takes place according to a selected cross section of the article to be formed by means of selective application of a radical initiator. The at least partially crosslinked material is added on layer by layer to a carrier or to previous layers bonded to the carrier. A system that is suitable for carrying out the method according to the invention has a substrate, a control unit, an application unit for applying the resin to the substrate, an application unit for applying an initiator to the resin, an energy exposure unit and a contacting unit.

ECO-FRIENDLY METHOD OF MANUFACTURING SHOE MATERIAL, SEMI-FINISHED, AND FOAMED SHOE MATERIAL MADE THEREBY
20230189924 · 2023-06-22 · ·

A method of manufacturing the foamed shoe material and semi-finished product including the following steps. Step S1: a foamable material is injected into a cavity of a blank mold to solidify, thereby generating a semi-finished product of the shoe material and a runner waste that are unfoamed. The runner waste could be shed for reusing directly as the foamable material without a granulating process. Step S2: the semi-finished product is cooled down and put into a cavity of the foaming mold, and the semi-finished product is evenly foamed in the cavity of the foaming mold to obtain a shoe material wherein the waste generated during the method of manufacturing the foamed shoe material could be effectively reused, and the yield rate of the shoe material thereby enhanced.
