Abstract: In an example, a method includes forming a layer of build material and selectively applying fusing agent on to the layer based on a predetermined pattern. Energy may be applied to the layer of build material, and at least one temperature of the layer may be measured. A temperature distribution over the layer of build material may be determined, the temperature distribution indicating, for each of a plurality of locations on the layer of build material, whether fusing agent is present at that location. At least one characteristic derived from the temperature distribution may be compared to a predetermined characteristic. When the compared characteristics differ, an operational characteristic of an additive manufacturing apparatus may be adjusted.

Abstract: In one example of the disclosure, a system for limitation of energy wavelengths applied during 3D printing includes an energy source to provide energy to a target zone during a 3D printing operation. The system includes a filter chamber through which the energy is to pass before arriving at the target zone. The system includes a filter chamber control component to selectively modify the contents of the filter chamber to limit the wavelengths of energy that can pass through the filter chamber based upon type of the target zone.

Abstract: An electromagnetic filtering system comprising an electromagnetic radiation source, a filter chamber to filter the radiation and a filter chamber control system to selectively modify the contents of the filter chamber in order to modify the wavelengths of the radiation that pass through the filter chamber. There is also provided a method of controlling an electromagnetic filtering system that comprises a controllable filter chamber capable of being controlled so as to selectively be filled with a filter material, the method comprising —determining filtering characteristics to be provided by the filtering system, —determining whether the filter chamber should be filled with the filter material, and —controlling the filter chamber to be filled as determined.

Abstract: Examples associated with printer configuration are disclosed. One example includes printing, using a printer, a first portion of a test patch in a first print direction. A second portion of the test patch is printed in a second print direction. The second portion is printed at a first offset from the first portion. A first portion of a second test patch is printed in the first print direction, and a second portion of the second test patch is printed in the second print direction at a second offset from the first portion of the second test patch. The printer is configured to print in the second print direction using one of the first offset and the second offset based on a selection between the first test patch and the second test patch.
