Abstract: The technology described herein includes a spreader that creates scattered incidental particles in a build chamber when spreading build material is applied in the build platform. One or more vacuum sources create negative pressure zones in one or more receptacles to collect the incidental particles in the build chamber during printing process and thus minimize the scattering of the incidental particles.

Abstract: According to examples, an apparatus may include a reflector having a parabolic shape, the reflector having a focal point and a plane of symmetry. The apparatus may also include a first energy emitter positioned at or near the focal point of the reflector, in which the reflector may reflect energy emitted from the first energy emitter in a first direction to a target area. The apparatus may further include a baffle extending along the plane of symmetry of the reflector, in which the baffle may absorb reflected energy directed to the baffle from the target area.

Abstract: In some examples, a printer includes a feed mechanism to distribute a build material on a platform and a heater. The heater includes a lamp, a reflector, and a radiant energy absorbing baffle located between the lamp and the reflector. The lamp and the reflector are to direct radiant energy toward the platform, and the radiant energy is to heat the build material.

Abstract: According to one aspect, there is provided apparatus for forming a layer of build material for three-dimensional printing. The apparatus comprises a spreader to spread a volume of build material to form a layer of build material on a build platform, wherein at least one end of the spreader is to remain a constant distance from a build material retaining wall in proximity to at least one edge of the build platform as the spreader is moved over the surface of the build platform, and further wherein at least a portion of the spreader is below the top of the retaining wall.

Abstract: A printer including a print bar and a dryer system. The print bar operates to deposit printing material in accordance with a print job. The dryer system operates to intake and heat air from an internal region in which one or more electrical components of the printer are located. The dryer system directs the heated air through multiple outlets that are acutely angled with respect to a location or media of deposited printing material, to dry the printing material while cooling the internal region of the printer.

Abstract: In one example, a reflector assembly includes a single reflector having at least two elliptical-shaped reflector cavities each with a respective focus point. The shape of the single reflector includes two partial elliptical-shaped reflector cavities having mirror-asymmetric profiles on each end of the single reflector each having a first side extending to a distal end and the first side longer than an opposite second side. The remaining elliptical-shaped reflector cavities have a first side and a second side the same length as the opposite second sides of the two partial elliptical-shaped reflector cavities.

Abstract: An airflow device includes a motor to drive an impeller to cause a first airflow and a second airflow. A housing at least partially encloses the motor and impeller, and the housing defines at least a first path and a second path. Via the first path, the first airflow recirculates and is heated with the first path including a first wall with a nozzle array through which the first airflow passes to contact printed media passing external to the first wall. The second path receives a second airflow of air to travel alongside the motor and exit through a first port to join the first airflow at the impeller.
