摘要： A system and method are disclosed for removal of unwanted material from additively manufactured parts by application of vibratory and/or acoustic energy. The system and method include a vibratory platform located in a chamber. Additively manufactured parts having unwanted material adhered thereto are placed on the vibratory platform. The platform is caused to vibrate thereby causing the unwanted material to detach from the parts. The system and method may also include the application of acoustic energy to cause unwanted material to detach from the parts. Advantageously, the unwanted material removed from the additively manufactured object can be recycled.

摘要： A system and method are disclosed for additively manufacturing an object to facilitate smoothing a surface of the object. An evaluation is made whether positioning the object with a specific orientation in a finishing apparatus is desirable and if so, the object is printed with an alignment feature. After printing the object, the object is positioned in the finishing apparatus using the alignment feature to provide the specific orientation in the finishing apparatus and the finishing apparatus is operated to smooth the surface of object. After smoothing the surface of the object, the alignment feature may be removed if necessary.

摘要： An apparatus and method for removing support material from and/or smoothing surfaces of an additively manufactured part is disclosed. The apparatus may include a chamber, a support surface within the chamber, one or more nozzles within the chamber, a tank positioned below the nozzles, and a vision system. The vision system includes one or more cameras and other imagery obtaining sensors located in the chamber. The cameras and sensors obtain imagery of the additively manufactured part as it is being sprayed to finish the part. The imagery is displayed on a display panel located outside the apparatus or stored for later playback.
