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.

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.

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.

According to one example, there is provided a method of additive manufacturing that comprises obtaining data relating to a 3D object to be manufactured, forming a layer of build material on a build platform, applying a cooling agent in a pattern surrounding a portion of build material to be solidified, and applying energy only to the build material on which cooling agent is applied and to the surrounded portion of build material such that the surrounded portion of build material heats up sufficiently to coalesces, and such that build material on which cooling agent is applied is cooled by the cooling agent and is prevented from heating up sufficiently to coalesce.

A printing apparatus includes a carriage, a first detector module, and a second detector module. The carriage may selectively move a fluid applicator along a scanning path in a first scanning direction and a second scanning direction across a print zone to print on a media therein. The first detector module and second detector module may be coupled to the carriage. Further, the first detector module may include a first receiver and a first source to form a first detection region there between downstream of the carriage in the first scanning direction to detect an object therein. The second detector module may include a second receiver and a second source to form a second detection region there between downstream of the carriage in the second scanning direction to detect an object therein.
