    Abstract: A temperature sensor can include a resistor, a first electrical contact at a first end of the resistor, a second electrical contact at a second end of the resistor, and a resistance measuring device. The resistor can be formed of a matrix of sintered elemental transition metal particles interlocked with a matrix of fused thermoplastic polymer particles. The resistance measuring device can be connected to the first electrical contact and the second electrical contact to measure a resistance of the resistor.

    Abstract: A method of three-dimensional printing can include iteratively applying a polymer build material as individual layers to a powder bed, where the polymer build material includes from about 80 wt% to 100 wt% polymeric particles, and based on a three-dimensional object model, selectively applying a coalescing agent onto individual layers of the polymer build material. The coalescing agent can include an aqueous liquid vehicle and a coalescing solvent that depresses a melting point of the polymeric particles. The method can include exposing the powder bed to heat to selectively coalesce portions of individual layers of the polymer build material in contact with the coalescing solvent. The heat may not be sufficient to coalesce the polymer build material that is not in contact with the coalescing solvent and may be sufficient to fuse the polymeric particles in contact with the coalescing solvent together to form a three-dimensional object.

    Abstract: Methods of three-dimensional printing can include iteratively applying a polymer build material as individual layers to a powder bed, where the polymer build material includes from about 80 wt% to 100 wt% polymer build particles, and based on a three-dimensional object model, selectively applying a binder agent including an aqueous liquid vehicle and polymer binder particles onto the individual layers of the polymer build material. The polymer binder particles have or are capable of having a melting temperature lower than a melting temperature of the polymer build particles. The methods can include exposing the powder bed to heat at a temperature less than a melting point of the polymer build particles but greater than a melting temperature of the polymer binder particles. The heat causes the polymer binder particles to melt to adhere the polymer build particles together to form a three-dimensional object.

    Abstract: In one example, testing cells extend along a length of a slot. Each testing cell includes a microfluidic channel extending from the slot, a pump to move fluid from the slot into the channel, a discharge nozzle through which fluid exits the channel, a fluid discharger to discharge fluid from the channel through the nozzle and a photosensor. A light guide is provided to receive light from an external light source and is to serially transmit the light to the microfluidic channel of each of the plurality of testing cells.
