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: A method of making a dental restoration has the steps of: determining a virtual space available for accommodation of a dental restoration for a tooth to be restored; retrieving a predefined virtual master dental restoration surface from a database; fitting the virtual master dental restoration surface in the space to provide a virtual outer dental restoration surface; creating a virtual inner dental restoration surface independent of a shape of the tooth to be restored; providing a virtual model of a dental restoration based on a combination of the virtual outer dental restoration surface and the virtual inner dental restoration surface; and fabricating the dental restoration based on the dental restoration model.
