Abstract

The invention discloses a part powder outlet hole repairing method in powder laying printing, and relates to the technical field of 3D printing. The problem that in traditional powder outlet hole repairing, due to the gas reverse phenomenon generated in welding of a last powder outlet hole, welding cannot be conducted or the welding quality does not reach the standard is solved. The part powder outlet hole repairing method in powder laying printing comprises the steps that a powder laying printing sample piece and a blocking piece are included, a powder outlet hole is formed in the sample piece, and the powder outlet hole is matched with the blocking piece in shape and size; and laser welding is conducted on the sample piece and the blocking piece under the vacuum environment, and the blocking piece blocks the powder outlet hole. The part powder outlet hole repairing method in powder laying printing is used for repairing work of the part powder outlet hole in 3D powder laying printing.

Description

technical field [0001] The invention relates to the technical field of powder coating 3D printing, in particular to a method for repairing powder outlet holes of parts in powder coating printing. Background technique [0002] In powder laying 3D printing, according to the design requirements of parts, some parts with structures such as internal cavity flow channels, support ribs or weight-reducing slots need to reserve powder outlet holes during the powder laying printing process to facilitate the processing of the parts. Perform powder cleaning operation, and some parts need to ensure the airtightness of the internal structure in structural design. Under this design requirement, the repair of the powder outlet hole after printing has become a major problem. At present, the main method for repairing the powder outlet hole is argon arc welding. Parts, argon arc welding needs argon protection on the back of the weld, so at least one powder outlet hole must be reserved for arg...
