WebbWe developed a 3D-printing process based on thermoset biocomposites termed Delayed Extrusion of Cold Masterbatch (DECMA). DECMA is a processing method, based on controlling the degree of curing, that takes some responsibility of the 3D printing from materials and as such can be used to 3D print otherwise unprintable materials. Webb10 nov. 2024 · Adding pressure, a catalyst, or a hardener can increase the curing rate. Once cured, a thermosetting plastic cannot be re-melted, so it is formed into its final shape by injection molding, extrusion molding, compression molding, or spin casting. Thermosetting Plastic Examples. Many plastics encountered in daily life are thermosetting plastics.
