Abstract: In some examples, data representing a three-dimensional object is received. The data may comprise an object property description associated with each of a plurality of locations within the object. At least one object generation parameter description associated with a region of the object may be determined from the data. The object generation parameter description may comprise at least one object generation apparatus control parameter value and a probability that control data generated therefrom will specify said object generation apparatus control parameter value for generating the region of the object.

Abstract: According to an example, a three-dimensional (3D) printer may include a first delivery device to selectively deposit a fusing agent onto a layer of build materials and a second delivery device to deposit coolant droplets at tuned drop weights onto the layer of build materials. The 3D printer may also include a controller to control the second delivery device to selectively deposit the coolant droplets at the tuned drop weights onto selected areas of the build material layer, in which the drop weights of the selectively deposited coolant droplets are tuned to provide a thermal balance between multiple areas of the build material layer during application of fusing radiation onto the build material layer.

Abstract: A sample comprising a first substance and a second substance is modified by breaking down molecular bonds of the second substance of the sample to form a modified sample having altered surface enhanced luminescence (SEL) characteristics to reduce overlapping of SEL characteristics of the first substance in the second substance. Surface enhanced luminescence data resulting from excitation of the modified sample is collected. Characteristics of the first substance based upon the collected surface enhanced luminescence data are identified.

Abstract: According to an example, an apparatus may include a memory that may store instructions to cause a processor to generate, for each part to be fabricated in a build envelope of a 3D fabricating device, first level descriptions and second level descriptions for the part. The processor may determine, using the first level descriptions, whether there is an arrangement that results in the parts jointly fitting within the build envelope while providing certain thermal decoupling spaces between the parts. In response to a determination that the arrangement using the first level descriptions for the parts has not been determined, the processor may determine, using the second level descriptions, whether there is an arrangement that results in the parts jointly fitting within the build envelope while providing the certain thermal decoupling spaces.

Abstract: According to an example, a three-dimensional (3D) printer may include a first delivery device to selectively deposit first liquid droplets onto a layer of build materials, in which the first liquid has a fusing radiation absorption property. The 3D printer may also include a fusing radiation generator to selectively emit fusing radiation at multiple ranges of wavelengths and at selected locations to selectively fuse the build materials and a controller to tune a range of wavelengths at which the fusing radiation generator is to emit fusing radiation based upon the fusing radiation absorbing property of the deposited first liquid, to determine the selected locations at which the fusing radiation at the tuned range of wavelengths is to be emitted, and to control the fusing radiation generator to selectively emit fusing radiation at the tuned range of wavelengths and onto the selected locations.

Abstract: Examples of methods are described herein. In some examples, a method includes generating a plot of a fluorescence signal over time. In some examples, the fluorescence signal is measured from a substance. In some examples, the method includes detecting, using a machine learning model, a target molecule in the substance based on the plot.

Abstract: An example device includes a first droplet ejector including a first nozzle to eject droplets of a first fluid, and a first target medium positioned relative to the first droplet ejector to receive the droplets of the first fluid from the first droplet ejector. The example device further includes a second droplet ejector in fluid communication with the first target medium to receive a second fluid from the first target medium. The second droplet ejector includes a second nozzle to eject droplets of the second fluid.
