Abstract

The invention discloses forming and detecting integrated 3D printing equipment. The forming and detecting integrated 3D printing equipment comprises a laser generator, an upper vacuum box, an industrial personal computer and a movable laser detecting and receiving system. The movable laser detecting and receiving system is installed in the upper vacuum box and comprises an XY stepping system and afocusing mirror. The focusing mirror is installed on the XY stepping system. The industrial personal computer controls the laser generator to generate detecting laser. The detecting laser is emittedinto the focusing mirror through an optical fiber. A detecting laser beam emitted by the focusing mirror perpendicularly irradiates a forming face, is received by the focusing mirror after being reflected and then is output to the industrial personal computer through the optical fiber. The industrial personal computer analyzes received optical signals. The industrial personal computer controls theXY stepping system to drive the focusing mirror to move, and defect detection is conducted on the whole forming face. The forming and detecting integrated 3D printing equipment conducts defect detection in time in the forming process, the production cost is reduced, and the production period is shortened.

Description

technical field [0001] The invention relates to the field of metal additive manufacturing, in particular to a 3D printing device integrating forming and testing. Background technique [0002] In the field of metal additive manufacturing, due to the different sizes of metal powders, fluctuations in the energy of the laser beam, and the oxidation of metal powders during the molding process, defects such as tiny pores inside the molded parts will result. In response to these defects, the existing technology uses X-ray transmission inspection after the parts are manufactured. Since the forming defects cannot be detected and found in the process of forming the parts, the formed parts may be scrapped, thereby increasing the production cost and production cycle. Contents of the invention [0003] The purpose of the present invention is to provide a 3D printing device integrating forming and testing, which can detect defects immediately during the forming process, so as to reduce ...
