A method is disclosed for generating a 3D printing file containing an object model of a part having a body and an integral electronic component. To generate the 3D printing file, a processor receives at least one geometry specification of the part to be printed and at least one component performance property of the electronic component to be printed integral to the part. An object model is determined by the processor in accordance with the at least one geometry specification of a part to be printed, the at least one component performance property of an electronic component to be printed, and at least one material property of an electronic component printing material of a 3D printer. The 3D printing file is generated by the processor and comprises the object model.

A method and system for a three dimensional printing system are described herein. In one example, the three dimensional printing system has a moveable carriage, an array of laser modules and a print controller. In this example, the moveable carriage has a print head arranged to selectively deposit a printing agent on to a layer of build material as the moveable carriage is moved relative to the layer of build material. The printing agent controls localized fusing of the build material on application of energy. The print controller is communicatively coupled to the array of laser modules and controls activation of individual laser modules of the array of laser modules so as to apply, selectively, energy to addressable sub-regions of the layer of build material on which printing agent has been deposited to control fusing together with the deposited printing agent.

Three dimensional printing system

Electrical resistor heating with an electrical resistor heating circuitry which includes an AC power source of at least one phase, a plurality of heating resistors provided in a spatial arrangement, and switches to connect the AC power source with the heating resistors generating ON and OFF power states. Power scheduling is provided to adjust the power fed from the AC power source to the heating resistors at a desired partial-power level by ON/OFF switching a number of switches, wherein the power scheduling causes at least some of the switches to switch between the ON and OFF states in a staggered manner so that energization of the partial-power level of different resistors takes place, at least partially, non-simultaneously.

Methods for curing ink printed on a print medium are disclosed. The methods comprise heating air to a temperature suitable for curing the ink, and blowing the air through a plurality of holes onto the print medium.

Printing apparatus and methods

A printer comprises a heating system to produce a hot-air flowimpinging on a print media, the heating system comprising a heat source, a fan, and an air chamber. The air chamber has an air-impinging plate with air-impinging holes adjacent to the print media. The heating system provides first and second partially overlapping hot-air circulation circuits. The first hot-air circulation circuit leads from the heater through the holes of the air-impinging plate to direct hot air through the air-impinging holes to the print media in the course of printing operation. The second hot-air circulation circuit leads back to the heater through a recirculation channel without passing through the air-impinging holes of the air-impinging plate to prevent air from being directed onto the print media, in the course of the heat-up operation. The heating system further comprises circuit-switching arranged to switch the air flow between the first and second hot-air circulation circuits.

Producing a hot-air flow in a printer to heat a print media

System for supplying ink printed on a print medium comprises a heater to heat air, an impingement plate with a plurality of holes, and a blower for blowing heated air through the holes of the impingement plate onto the print medium. The impingement flux length in the system which may be defined as the length of the impingement plate through which heated air is blown, is adjustable.

Systems for supplying heated air to printed ink

Ink drying apparatus and method for controlling ink drying apparatus are described herein. An example ink drying apparatus includes first and second heating elements positioned adjacent a drying area in a printer, and a controller to determine a temperature of the heating area and to selectively operate, based on the temperature determination, the first heating element in a burst mode and the second heating element in an on/off mode.

A system for pre-heating print media includes a carriage: a plurality of printheads disposed on the carriage; and a plurality of heating lamps disposed on the carriage such that each of the printheads is associated with at least one of the heating lamps. Each of the heating lamps heats a corresponding portion of a print medium prior to arrival of a printhead associated with that heating lamp at that portion of the print medium.
