Abstract
The invention relates to a method for manufacturing a mould body (40) serving as an original or master or, alternatively, a matrix, said mould body having at least one surface area (41a) in the form of a microstructure, designed so that it can be transferred as a complementary surface area to a matrix or an object. The mould body (40) is constructed from one or more prefabricated discrete elements (41). A base plate belonging to the mould body (40) is applied and secured in at least one of these discrete elements (41). This element shall be provided with said surface area (41a) in the form of a microstructure. A matrix or object formed by the mould body (40) is provided with a complementary microstructured surface area from said discrete elements.The invention also relates to a mould body produced in this way.
