A Slurry Recovery System for Selective Laser Melting Forming

Abstract

The present invention proposes a selective laser melting forming slurry recovery system. The transfer bin of the system is connected to the forming system through the receiving port, and the solid-liquid separation cavity is connected to the lower part of the transfer bin through a pressure-sensing electromagnetic valve. A pressure plate is installed in the cavity, which is controlled by a hydraulic cylinder to move up and down in the cavity. The first discharge port and the second discharge port are set on the solid-liquid separation cavity and connected to the powder collector at the same time, and an electric switch is installed on the first discharge port. , Install a pressure valve on the second discharge port, install a separation liquid collector at the bottom of the solid-liquid separation chamber, and install a filter screen at the connection. The slurry recovery system of the present invention solves the problem that the organic solvent slurry SLM is difficult to recover after forming, realizes the reuse of metal powder and reinforcement materials in the slurry, and reduces the cost of SLM forming.

Description

technical field [0001] The invention belongs to the technical field of additive manufacturing, and relates to selective laser melting 3D forming, in particular to a recycling system for selective laser melting forming slurry. Background technique [0002] 3D printing (additive manufacturing) technology is a technology that uses CAD design data to manufacture solid parts by layer-by-layer accumulation of materials. Compared with the traditional cutting process, it is a "bottom-up" material accumulation manufacturing method. Additive manufacturing technology does not require traditional tools, fixtures, and multiple processing procedures. Using 3D design data, parts of arbitrary complex shapes can be quickly and accurately manufactured on one device, thereby realizing the "freedom" of complex structural parts that were difficult to manufacture in the past. "manufacturing" forming, and greatly reduce the processing steps and processing cycle. [0003] Typical 3D printing tech...
