Abstract
A process of producing a surface-modified 3-dimensional article, the process comprising the steps of providing a radiation-curable composition, building-up a 3-dimensional article by radiation-curing the radiation-curable composition layer by layer, preferably by using a stereolithography or digital light processing unit, partially removing radiation-curable composition which sticks to the surface of the 3-dimensional article, treating only a portion of the surface of the 3-dimensional article to which the radiation-curable composition is stuck with particles, applying an additional curing step to the 3-dimensional article, preferably by applying heat and/or radiation. A 3-dimensional article which can be obtained by such a process and a kit of parts comprising such a 3-dimensional article.
