When most people are concerned about the subsequent processing of ABS prints, few people think of metal powder 3D printing . Nowadays, many companies have begun to pay attention to metal 3D printing. However, how many people can understand the risks and problems in the metal 3D printing process?
Big companies like General Electric are indeed aware of this problem and are therefore taking steps. It can be said that if the leakage of ABS material is only a small trouble, metal powder leakage is a big problem.
Aside from the unknown and invisible harmful substances, the threat posed by metal powder is obvious and real, especially when it enters the eye or wound. Therefore, experts recommend that anyone close to a metal 3D printer wear a high temperature lab coat, wear a clear eye mask, and wear a nitrile glove that is at least 5 mm thick. Metal printing is still a manual charge until a better charging method occurs. These protective measures are necessary when loading the printer with powdered materials. Experts believe that when the machine is running, it is necessary to put on protective clothing and put on a respirator. The facial respirator can filter out 99.97% of particles below 5 microns. Of course, sometimes it is impossible to avoid contact with metal powder. For example, in the subsequent processing of metal prints, the operator will inevitably touch the metal powder.
Although ABS or other plastic printing materials can produce smoke and some carcinogens, metal 3D printing may produce more dangerous substances. such as:
Harmful gases generated during oxygen replacement - usually occur during argon or nitrogen replacement of oxygen. When multiple machines are operating at the same time and the ventilation is not good, carbon monoxide may be generated during the replacement of oxygen by argon and nitrogen. Therefore, monitoring the oxygen index is very important.
Static electricity and fire - For fires caused by metal powder, special fire extinguishers must be prepared at all times, and fire drills should be done in peacetime. Operators must learn to use a D-type fire extinguisher to extinguish a metal flame.
In order to reduce the occurrence of fire, experts recommend:
The printer must be connected to a wire;
The body must be equipped with antistatic devices;
The floor must be equipped with a vacuum cleaner;
The floor must have an antistatic coating;
The operator must wear antistatic shoes;
There must be a D-type fire extinguisher next to the metal 3D printer.
