Abstract: A method of manufacturing pre-formed, customized, ceramic, labial/lingual orthodontic clear aligner attachments (CCAA) by additive manufacturing (AM) may comprise measuring dentition data of a profile of teeth of a patient, based on the dentition data, creating a three dimensional computer-assisted design (3D CAD) model of the patient's teeth using reverse engineering, and saving the 3D CAD model, designing a 3D CAD structure model for one or more CCAA on various parts of each tooth, importing data related to the 3D CAD CCAA structure model into an AM machine, directly producing the CCAA in the ceramic slurry-based AM machine by layer manufacturing, enabling the provider to deliver patient-specific CCAA's by an indirect bonding method to the patient's teeth to improve the efficacy and retention of the clear aligners.

Abstract: The invention refers to a device for generative production of components, in particular by means of selective melting or sintering, comprising a light source for generating a light beam, a processing head that is either coupled to the light source by means of a beam guide, so that the light beam is guided to the processing head, or the light source is arranged directly on the processing head, so that a light beam can be directed from the processing head to a processing area, the processing head being mounted movably, so that the light beam can be directed to any desired location on the processing area. The invention is characterized in that several processing heads are provided for the respectively directing a light beam onto the processing area, and the processing heads are each arranged on a carriage that can be moved along a traverse. This allows powder to be melted or sintered simultaneous at several locations. Preferably, the processing heads are arranged on swivel arms. This allows a very simple and cost-effective design of the device.

Abstract: In one example in accordance with the present disclosure, an additive manufacturing system is described. The additive manufacturing system includes a build material distributor to deposit metal powder build material and an agent distribution system to selectively deposit a binding agent on the metal powder build material in a pattern of a layer of a three-dimensional (3D) object to be printed. The additive manufacturing system also includes an ultraviolet (UV) energy source. The UV energy source, in a layer-by-layer fashion 1) cures the binding agent to join together metal powder build material with binding agent disposed thereon and 2) evaporates a solvent of the binding agent.
