Abstract: A method of making a physical object by additive manufacturing. In the method a hardenable primary material is provided, the object is built up by successively hardening layers of the hardenable primary material, and the object is cleaned from excess material by moving the object and thereby generating a mass inertial force in the excess material. The invention facilitates the making of objects by additive manufacturing.

Abstract: The invention relates to a process of producing a surface-modified non-metallic dental article, the process comprising the steps of providing a non-metallic dental article having an outer and an inner surface, applying a curable composition on the inner surface of the dental article (to form a layer of the curable composition on the inner surface), applying particles on the curable composition located on the inner surface of the dental article to achieve a surface roughness Ra of 1 to 30 μm, curing the applied curable composition, the chemical composition of the curable composition being different from the chemical composition of the dental article. The invention also relates to a surface-modified non-metallic dental article obtained or obtainable by such a process and a kit of parts comprising such a surface-modified non-metallic dental article and a dental cement.

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.

Abstract: A method of making a physical object by additive manufacturing. The method has the steps of providing a light hard-enable primary material (11), building up the object (100) by successively hardening portions of the light hardenable primary material (11) by irradiating the portions with light, coating at least a part of the object (100) with a light permeable coating or oxygen protective material; and irradiating the coated object (100) with light and thereby post-hardening any light hardenable material (11).
