Abstract
Provided are: a 3D printer using a robot and enabling molding of an article with high strength and high accuracy; and a control apparatus for said robot. A robot used as this 3D printer has: an input-side encoder that acquires information regarding the angle of an input axis of a joint of the robot operated on the basis of a control command; and an output-side encoder that acquires information regarding the angle of an output axis. A calculation unit of this control apparatus has: a control command storage unit having stored therein a control command for motors of respective axes of the robot; a deviation estimation unit that receives results of detection by both of the input-side encoder and the output-side encoder and estimates the deviation of an actual trajectory of the robot from the control command; and a control command correction unit that corrects the control command by using the estimation result by the deviation estimation unit.
