Abstract: A method is provided for additive manufacturing. This method includes monitoring a current to a recoater blade. The monitored current is compared to a predetermined current. An operation is initiated in response to the monitored current exceeding the predetermined current. Another method for additive manufacturing includes comparing a movement of a recoater blade to an expected movement. A single exposure sequence is initiated in response to movement of the recoater blade being different than an expected movement. An additive manufacturing system is also provided which includes a recoated blade and a control. The control is operable to identify resistance to movement of the recoater blade.
