Title:
3D ADDITIVE MANUFACTURING DEVICE, CONTROL METHOD FOR 3D ADDITIVE MANUFACTURING DEVICE, AND CONTROL PROGRAM FOR 3D ADDITIVE MANUFACTURING DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/163428
Kind Code:
A1
Abstract:
The present invention manufactures a 3D additively manufactured object with a high degree of precision. Provided is a 3D additive manufacturing device that is equipped with a material injecting unit for injecting material for the 3D additively manufactured object upon a manufacturing base. The 3D additive manufacturing device is also equipped with a light beam irradiating unit for irradiating the injected material with light beams. The 3D additive manufacturing device is further equipped with a beam pathway controlling unit that is disposed upon the beam pathway of the light beams, detects the convergence position of the material upon the manufacturing surface, and controls the beam pathway of the light beams on the basis of the detected convergence position. The beam pathway controlling unit determines the focusing position of the light beams relative to the convergence position.
