Some three-dimensional printing techniques, such as selective laser sintering (SLS), may involve: (1) planning a printer tray for a 3D printer for printing one or more 3D objects; (2) using the 3D printer to print the 3D object(s); (3) cooling the printer tray; (4) extracting the printed 3D objects from the printer tray; and (5) post-processing one or more of the extracted 3D objects (e.g., by dyeing or tumbling). When a printer tray includes multiple printed 3D objects, the printed 3D objects may be sorted to determine which customer(s) ordered the 3D objects. The printed 3D object(s) may be provided to the customer(s) who ordered the 3D object(s).
Planning a printer tray for a 3D printer may involve identifying a set of 3D objects to print in the printer tray and creating a packing plan specifying where in the printer tray each of the 3D objects in the set is to be printed.
