A 3D printed glove boxes play a crucial role in the metal 3D printing process. It provides a safe working environment for metal 3D printing and can effectively solve many problems in the 3D printing process. For example, it can provide a pure working atmosphere environment, forming a closed loop with multi-stage dust collection devices and circulation devices. Argon gas circulates in the closed loop, making the water and oxygen content in the system reach the target of less than 1PPM, achieving an ultra-high purity working atmosphere environment and reducing the adverse effects of oxygen on metal printing processes such as titanium alloys, such as oxygen embrittlement.

A The working gas inside the glove box usually does not need to be replaced frequently under normal circumstances, which means that the glove box does not need to be cleaned frequently. If the sealing of the glove box is good, the gas circulation system and purification system can work normally, and the working gas (such as inert gas nitrogen or argon) can be circulated inside the box. The gas circulation system will continuously make the gas flow inside the box and pass through the purification system to remove oxygen, moisture, and other impurities, thereby maintaining the stability of the environment inside the box. For example, when a high-quality glove box is used for lithium battery material research, as long as its gas purification system continues to operate effectively and the working gas can be maintained within a suitable purity range for a long time to meet experimental requirements, there is no need to replace the gas inside the glove box.

A Malfunctions in the gas circulation and purification system can lead to an increase in the gas consumption of the glove box. When the circulating fan is abnormal, motor failure, impeller damage or unstable speed will reduce the gas circulation efficiency, and impurities in the box cannot be treated in a timely manner. To ensure that the environment meets the requirements, the system will supplement more working gas; Blockage or leakage in the circulation pipeline can hinder the normal circulation of gas, causing gas in some areas to be unable to renew and impurities to accumulate. Leakage can directly lead to gas loss, requiring more gas to maintain the environment; The failure of purification materials, such as molecular sieve adsorption saturation and copper catalyst failure, cannot effectively purify gases. As a result, the water and oxygen content in the glove box increases, and the system will increase the supply of working gas to maintain the ideal environment.

A The increase in gas consumption of glove boxes is related to their sealing performance, and problems with the sealing of glove box equipment can lead to an increase in gas consumption. When there are small holes, cracks, or aging wear on the gloves, external air enters, and the system will replenish more working gas to maintain the indoor environment; If the sealing gaskets around the interface between the gloves and the box, the transition chamber door, and the pipeline interface are aged, damaged, or not installed properly, gas leakage will cause a decrease in pressure inside the box, and the gas supply system will increase the gas supply; If there are leakage problems such as welding cracks or small pores in the material of the box itself, it will also cause gas loss, leading to the system replenishing more gas to maintain pressure balance.

A An increase in the gas consumption of the glove box may cause abnormal pressure changes inside the box, causing pressure on the box structure, which may lead to deformation or rupture of the box, or allow a large amount of external air to enter, damaging the pure experimental environment. In addition, the gas composition may change, affecting experiments that are sensitive to oxygen and moisture. The purification system may become overloaded due to an increase in gas consumption, making it difficult to remove impurities from the newly replenished gas in a timely manner, resulting in a decrease in the purification effect inside the glove box and affecting the experimental results.

A Sudden increase in gas consumption in the glove box may cause abnormal gas source pressure. If the output pressure of the gas source cannot meet the demand, it may lead to insufficient gas supply or high pressure, affecting the working environment inside the glove box, and even damaging sensitive equipment or causing glove breakage. At the same time, the risk of gas leakage increases. Due to the increase in workload, it may lead to increased wear and tear of the sealing gasket at the pipeline interface, causing gas leakage. If inert gas is leaked, it may cause suffocation of operators, and flammable and explosive gases may pose a more serious danger.
