Abstract
A method is provided for producing a molded article from a non-thermoplastic material. The method includes: supplying the non-thermoplastic elastomer material to a processing unit; processing the non-thermoplastic elastomer material to generate a material flow of the non-thermoplastic elastomer material; conveying the non-thermoplastic elastomer material into an accumulator unit to generate a nominal pressure of the non-thermoplastic elastomer material in the accumulator unit; conveying the non-thermoplastic elastomer material to a molding unit to selectively output at least one layer of the molded article to be formed; and cross-linking the at least one layer of the molded article or of the entire molded article by means of a cross-linking unit. The non-thermoplastic elastomer material is highly viscous, and has a viscosity in the range of 100 to 1,000,000 Pa·s.
