  • Platform drop sensor
    Patent number: 11052606
    Abstract: A method of detecting a malfunction event in an additive manufacturing system includes building a workpiece with the additive manufacturing system. The additive manufacturing system includes a housing, a build chamber disposed within the housing, a recoater disposed within the build chamber, a build platform configured to receive the workpiece, a shaft mounted to the build platform, a sensor in operable communication with the additive manufacturing system, and an actuating mechanism engaged with the shaft such that the actuating mechanism is configured to move the shaft relative to the actuating mechanism. The undesirable event is sensed with the sensor.
