Abstract
A droplet discharge apparatus includes a discharge head including a nozzle, a nozzle surface observation device, and processing circuitry. The discharge head including the nozzle is configured to discharge a droplet onto a discharge receiving medium formed of powder. The nozzle surface observation device is configured to observe a nozzle surface of the nozzle of the discharge head. The processing circuitry is configured to calculate an adhesion amount of attached matter to the nozzle surface based on an observation result of the nozzle surface observation device. The processing circuitry is configured to determine, based on a calculation result of the adhesion amount of the attached matter, an operation on a control target that controls at least one of a mass and a discharge speed of the droplet.
