Abstract: Examples of a 3D printing apparatus arranged to perform a print operation using build material, and methods of operating such a 3D printing apparatus, are described. In one case, a 3D printer is arranged to perform a print operation using build material whilst a build material temperature sensed by the printer is below a threshold temperature of the build material. The printer is arranged to obtain a threshold temperature indicator in advance of a respective print operation.

Abstract: An apparatus and method for performing a print operation on a 3D printer (110) are described herein. A 3D printing apparatus comprising a 3D printer (110) is arranged to perform a print operation using build material from a build unit (120) unless a value that identifies a first build material stored in the build unit in a first register, which is set according to an initial build powder fill operation of the build unit (120) by a powder management station, is different from a value in a second register, which is set according to the initial build powder fill operation, or modified in response to, or following, a subsequent opening of the build unit (120).

Abstract: Certain examples relate to encoding data into three-dimensional objects. In one case, a location of a set of terminals to be accessed on an outer surface of the object after fabrication is determined. A mapping between data to be encoded and an electrical property to be measured via a conductive coupling and an embedded electrical structure with the electrical property are determined. Control data is generated to instruct the fabrication of the object with the set of terminals and the embedded electrical structure.

Abstract: According to one aspect, there is provided a management system to control a 3D printing system that includes at least one 3D printer, at least one build unit in which 3D objects can be generated by the 3D printer, and at least one material processing unit in which processing operations can be performed on the build unit. The management system comprises a processor to obtain status data from at least some of the elements of the 3D printing system, to obtain data relating to a print job to be printed, to determine, from the obtained data, a schedule of operations to be performed by elements of the 3D printing system and to generate control data to allow enforcement of the determined schedule.

Abstract: A three-dimensional printer comprising means for build material, a printer carriage and a curtain. The means for depositing the build material deposits same on a printing zone and/or on one or more build material layers deposited on the printing zone. The printer carriage is to move along a first axis over the printing zone and comprises means for treating the build material. The curtain is attached to a first side of the printer carriage with a first side of the curtain and/or configured to move along with the printer carriage such that the curtain covers at least an area of the print zone, wherein the area varies dependent on the moving of the printer carriage over the print zone.
