In one example in accordance with the present disclosure, a system is described. The system includes a reader to read an identifier from a storage element associated with a part. An extractor of the system extracts, based on the identifier, lifecycle conditions specific to the part. A controller of the system alters manufacturing operations based on extracted lifecycle conditions for the part.

Lifecycle condition-based manufacturing alteration

In one example in accordance with the present disclosure, a system is described. The system includes a reader to 1) read an identifier from a three-dimensional (3D) System printed object that includes a storage element and 2) read a location of the 3D printed object within a build material bed. An extractor of the system extracts, based on the identifier, a post processing operation to execute on the 3D printed object. A controller of the system controls a post processing operation based on extracted post processing operation information and the location.

Automated handling based on part identifier and location

In an example, a method is described that includes building a first layer of a three-dimensional heterogeneous object in a first plurality of passes of an additive manufacturing system. An electronic component is inserted directly into the first layer. The electronic component is then fused to the first layer in a second plurality of passes of the additive manufacturing system.

Fusing electronic components into three-dimensional objects via additive manufacturing processes

In one example in accordance with the present disclosure, a system is described. The system includes a reader to read an identifier associated with a part. An extractor of the system extracts, based on the identifier, sensor output data for the part. A transmitter of the system transmits a re-order request for the part based on the sensor output data.

Part re-order based on part-specific sensor data

In one example, a device for printing a three-dimensional object is described. The device may include at least one material application unit to deposit at least one material for a voxel of the three-dimensional object, a vertical cavity surface emitting laser array comprising a plurality of vertical cavity surface emitting lasers, the plurality of vertical cavity surface emitting lasers including a first vertical cavity surface emitting laser to operate at a first wavelength and a second vertical cavity surface emitting laser to operate at a second wavelength, and a processor to control a deposition of the at least one material for the voxel via the at least one material application unit and to control an application of electromagnetic energy via at least one of the plurality of vertical cavity surface emitting lasers to the voxel to alter at least one property of the at least one material.

Printing devices

According to examples, an apparatus may include a printhead assembly containing a housing supporting a printhead. The printhead may have nozzles that are to fire droplets of a functional agent onto a layer of build material particles along respective flight paths to form sections of a 3D object from the build material particles, an array of light emission devices to direct respective light beams in the respective flight paths, and an array of photon detectors to detect respective light beams directed from a light source of the array of light emission devices, the light emission devices and the photon detectors being supported on the housing. The apparatus may also include a controller to determine whether any of the nozzles is operating improperly based upon whether the photon detectors detected the light beams and to output an instruction regarding an improperly operating nozzle in response to a determination that the nozzle is operating improperly.

Printhead assembly with light emission devices and photon detectors

One example of a device includes a sensor, a memristor code comparator, and a controller. The sensor is to provide a sensor signal. The memristor code comparator is to compare the sensor signal to a reference signal. The controller is to determine a status of the sensor signal based on the comparison.
