  • Method and device for production of a three-dimensional article
    Patent number: 7767130
    Abstract: The invention relates to a method and device for production of a three-dimensional article from a material, by means of layered application. According to the invention, a dropwise application is carried out, whereby drops of reaction components are ejected by a nozzle arrangement (3) and applied to a base reaction component (2), arranged on a substrate (1). The material for the three-dimensional article is formed in layers, with reaction of the base reaction component (2) with reaction components on contact, whereby the material is formed on a reaction of the base reaction component with one of the reaction components to give a material with one material property and on another reaction of the base reaction component with another of the reaction components to give a material with another material property. On production of the three-dimensional article, an article section is produced in which a gradual transition between the one material property and the other material property is generated.
