AI Technical Summary

Technical Problem

In the existing 3D printing technology, the melting temperature of metal powder is high, resulting in slow laser scanning speed, affecting printing efficiency; at the same time, the machining accuracy of large-scale parts is poor, and when multiple small-form laser scanning galvanometers are combined, the misalignment and installation space problems lead to low efficiency.

Method used

A laser scanning head for 3D printers is designed, and the structure of two inlet ports, two X galvanometers and two Y galvanometers is adopted. Through the symmetrical arrangement of the X galvanometer and the Y galvanometer, the light beams of the two inlet ports enter light on the same side, saving installation space; at the same time, a near-distance and dense cooling water circuit design is adopted to ensure the uniformity of the cooling effect.

Benefits of technology

The compact arrangement of multiple small scanning formats is achieved, which improves printing efficiency and processing accuracy, saves installation space, reduces laser energy requirements, and reduces the impact of thermal effects.

Abstract

The invention relates to the technical field of powder laser sintering manufacturing, and particularly discloses a laser scanning head for a 3D printer, the laser scanning head comprises a shell, a top cover and a galvanometer system, and the top cover is connected to the top end of the shell; the galvanometer system comprises two galvanometer brackets, two X galvanometers and two Y galvanometers; the two galvanometer supports are installed on the bottom faces of the two ends of the shell respectively, one side face of the shell is provided with light inlets corresponding to the two galvanometer supports respectively, and the bottom face of the shell is provided with light outlets corresponding to the two galvanometer supports respectively. The two X galvanometers are installed on the top faces of the two galvanometer supports and extend into the containing cavity, and the two X galvanometers are symmetrically arranged along the center line. The two Y galvanometers are installed on the side faces, away from the light inlets, of the two galvanometer supports respectively and stretch into the containing cavity, the axes of the two Y galvanometers are close to each other and are symmetrical about the center line, and the axes of the two Y galvanometers are located between the axes of the two light inlets. The scanning head has the effects of reducing the space volume occupied by the scanning head and improving the printing efficiency.
