摘要： 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.

摘要： An additive manufacturing machine includes a laser light source, a beam entry window, a recoater, a plurality of light sources attached to the recoater, a photosensor, and a controller. The laser light source emits laser light to selectively melt one or more portions of a working layer of a powder bed during additive manufacturing of a part. The beam entry window is positioned between the powder bed and the laser light source. The recoater moves across the powder bed to spread the working layer. The photo sensor senses intensity of light emitted by each of the plurality of light sources through the beam entry window. The controller correlates sensed intensity of the light emitted by each of the plurality of light sources through the beam entry window to corresponding positions on the beam entry window based on locations of each of the plurality of light sources.

摘要： Described herein are methods and systems for printing a three-dimensional object. In an example, a method for printing a three-dimensional object can comprise: (i) a metallic build material being applied; (ii) a binder fluid being applied on at least a portion of the metallic build material; (iii) the selectively applied binder fluid can be flash fused to bind the metallic build material and the selectively applied binder fluid by application of an energy flux having an energy density of from about 0.5 J/cm2 to about 20 J/cm2 for less than about 1 second. In the example, (i), (ii), and (iii) can be repeated at least one time to form the three-dimensional object. The binder fluid can comprise a liquid vehicle and polymer particles dispersed in the liquid vehicle.
