Abstract: In one example, a lighting device for an additive manufacturing machine includes first light sources each to emit monochromatic light within a first band of wavelengths that includes a peak light absorption of a liquid coalescing agent and second light sources each to emit monochromatic light within a second band of wavelengths different from the first band of wavelengths. Each of the first light sources or each of multiple groups of the first light sources is individually addressable to emit monochromatic light independent of any other of the first light sources or of any other group of the first light sources and each of the second light sources or each of multiple groups of the second light sources is individually addressable to emit monochromatic light independent of any other of the second light sources or of any other group of the second light sources.

Abstract: In an example, a lab-on-chip Raman spectroscopy system is described. The lab-on-chip system includes a housing having a fluid channel formed thereon. The fluid channel is coupled to an inlet and to an outlet. A surface-enhanced Raman spectroscopy substrate is positioned inside the fluid channel. The surface-enhanced Raman spectroscopy substrate includes a plasmonic nanostructure and a sacrificial, conformal passivation coating deposited over at least the plasmonic nanostructure.

Abstract: A 3D printing system includes a build material and an ink for patterning portions of the build material. The printing system further includes two or more susceptors, a first susceptor and a second susceptor. The first susceptor causes heating when exposed to microwave radiation at a first temperature. The second susceptor causes heating when exposed to microwave radiation at a second temperature. The first susceptor material is decomposable or oxidizable at a third temperature that is higher than the second temperature. The second susceptor is transparent to microwave radiation at the first temperature.

Abstract: A stabilizing liquid functional material (SLFM) for 3D printing includes ceramic nanoparticles in an amount ranging from about 0.25% to about 5% by weight based on a total SLFM weight and silica nanoparticles present in an amount ranging from about 0.1% to about 10% by weight based on the total SLFM weight. The ceramic nanoparticles have a particle size ranging from about 5 nm to about 50 nm. The silica nanoparticles have a particle size ranging from about 10 nm to about 50 nm. The ceramic nanoparticles and the silica nanoparticles are different in composition and/or morphology. An electromagnetic radiation absorber is present in an amount ranging from about 1% to about 10% by weight based on the total SLFM weight. An organic solvent is present in an amount from about 5% to about 50% by weight based on the total SLFM weight. The SLFM includes a balance of water.

Abstract: In one example, a method of fabricating a three-dimensional object includes depositing a layer of build material, depositing a coalescing agent onto the layer of build material according to a slice of three-dimensional model data, irradiating the coalescing agent with microwave radiation such that the coalescing agent converts the microwave radiation into heat to coalesce the build material in which the coalescing agent was deposited.
