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 article, has steps of (i) providing a layer of sinter powder, (ii) providing a solidifiable binder to form a circumferential fixation zone (114) which encloses a portion of the powder layer. The method further has the step of repeating steps (i) and (ii) with each fixation zone (114) of one layer being in contact with a fixation zone (114) of an adjacent layer such that a plurality of the fixation zones (114) together form a coherent hollow sleeve (116) extending across the layers. The corresponding plurality of powder portions in combination form a contiguous batch (118) of powder captured in the sleeve. The method facilitates the manufacturing of sintered dental articles.

Abstract: A system (1) for washing a 3D-printed object (4). The system (1) has a washing device (2) and a workpiece (3) that includes the 3D-printed object (4). The washing device (2) has a container (7) that forms a process chamber (8) for receiving a liquid cleaning agent (9), and the container (7) has an inlet (10) into the process chamber (8). The workpiece (3) further has a support structure (6) that supports the 3D-printed object (4) and a base (5) supporting the support structure (6). The base (5), in a mating relationship with the inlet (10), forms a restraint preventing the workpiece (3) from passing through the inlet (10) in a situation in which the workpiece (3) is placed with the 3D-printed object (4) located within the process chamber (8).

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).
