\n

The processing efficiency of the electron beam is much higher than that of the laser, and the processing cost is low<\/span> <\/p>\n<\/td>\n<\/tr>\n

\n

Processing methods<\/span> <\/p>\n<\/td>\n

\n

Hot processing, most materials do not need heat treatment<\/span> <\/p>\n<\/td>\n

\n

Cold processing, heat treatment required<\/span> <\/p>\n<\/td>\n

\n

The electron beam processing participation stress is very low, and the mechanical properties of the processed parts are excellent. Laser thermal stress is high, easy to deform and produce cracks<\/span> <\/p>\n<\/td>\n<\/tr>\n

\n

Processing environment<\/span> <\/p>\n<\/td>\n

\n

vacuum<\/span> <\/p>\n<\/td>\n

\n

Nitrogen<\/span><\/span><\/span> \/<\/span> argon protection<\/span><\/span> <\/p>\n<\/td>\n

Vacuum environment is more conducive to processing workpieces, electron beam equipment does not require a filter<\/span> <\/p>\n<\/td>\n<\/tr>\n

\n

\n

Processed parts can be free from the processing base<\/span> <\/p>\n<\/td>\n

\n

Sintered parts on the base plate<\/span> <\/p>\n<\/td>\n

\n

The electron beam directly shapes the parts. After the laser processing is completed, the bottom plate needs to be cut off.<\/span> <\/p>\n<\/td>\n<\/tr>\n

Powder localization and new material development<\/span> <\/p>\n<\/td>\n

\n

easily<\/span> <\/p>\n<\/td>\n

\n

difficult<\/span> <\/p>\n<\/td>\n

\n

Electron beam powder is easy to manufacture and easy to obtain. The ultra-fine powder of laser is difficult to process in China and the cost is extremely high. Electron beam equipment allows users to use their own powder<\/span> <\/p>\n<\/td>\n<\/tr>\n

\n

\n

CE<\/span> ,<\/span> FDA<\/span> <\/p>\n<\/td>\n

\n

The cost<\/span> <\/p>\n<\/td>\n

\n

low<\/span> <\/p>\n<\/td>\n

\n

high<\/span> <\/p>\n<\/td>\n

\n

The price of electron beam equipment is slightly more expensive than that of foreign laser equipment. Due to the price of powder and processing efficiency, the cost of using electron beam is much lower than that of laser equipment<\/span> <\/p>\n<\/td>\n<\/tr>\n

\n

Environmental pollution<\/span> <\/p>\n<\/td>\n

\n

No radiation pollution<\/span> <\/p>\n<\/td>\n

\n

Laser protection required<\/span> <\/p>\n<\/td>\n

\n

Indoors<\/span> where<\/span> SLM equipment is<\/span> stored<\/span> are prone to a decrease in oxygen content<\/span><\/span> <\/p>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

As far as the above table is concerned, electron beam forming seems to have more advantages than laser forming. However, at present, the laser forming process occupies a larger market scale, and the requirements of laser forming materials are more demanding. But no matter what, the key is the utilization rate of the machine! <\/p>\n
