Document Type and Number:
Japanese Patent JP6815522
Kind Code:
B2
Abstract:
Disclosed is a method for an all-laser hybrid additive manufacturing. After a matrix is obtained by means of selective laser melting forming, a subtractive forming is carried out on the matrix by means of a pulse laser to form a cavity, and the cavity is then packaged to obtain a forming material with an internal cavity structure. A laser precision packaging method is used in the method based on the melting of the laser selective region. Also disclosed is the apparatus, comprising a laser unit (2), a control unit (4) and a forming unit (6). The laser unit is in light path connection with the forming unit, and the control unit is electrically connected with the laser unit and the forming unit respectively. The laser unit comprises a first laser light source and a second laser light source. The forming unit comprises a welding unit (68), and the welding unit is controlled by the control unit and is matched with the laser unit for the additive manufacturing.
