3D Coater's self-recovery system and self-recovery method of 3D printer

摘要

The present invention relates to a self-recovery system of a three-dimensional printer capable of self-recovering a cotter. The self-recovery system comprises: a blade module for applying pressure to powder which is a material of the printout to the three-dimensional printer to homogenize the powder; a signal module for receiving a signal related to damage when the damage occurs to the blade module; and a control module which rotates the blade module to change a contact surface where the powder comes into contact with the blade module according to a signal of the signal module.
