  • Process and installation for the manufacture of parts by phototransformation of material
    Patent number: 5824259
    Abstract: A method and device for shortening the production run in a stereolithographic process in which a series of layers of liquid or virtually liquid material are cured by exposure to light to form an article. According to the method, at least one covering structure that closely fits the shape of the article is provided on at least one side of the article, whereby a region of reduced disturbance is created between the article and the covering structure during positioning of the layers of liquid or virtually liquid material. The length of time needed for the material to settle is thus substantially reduced.
