（2）Scanning layer thickness：20~40um
（5）Printing material：die steel, stainless steel,cobalt-chromium alloy, aluminium alloy and titanium alloy
（6）Laser：simple module fibre laser
（7）Galvanometer control card: bi-axial scanning control; control fiber laser
（8) Industrial control computer interface: adopt Windows7 system
（9） Gas cleaning unit: cavity model: The door opening method is handle type and the tube routine is arranged according to the use.
（10）Software control system: adopting advanced computer processing system for data acquisition, processing and storage. It has the advantages of good anti-electromagnetic interference, high performance, low power consumption, high precision and long life. It uses micro-controller hardware platform and embedded operation system software platform, which has the flexible system upgrade capability and various communication methods such as RS-485. It also has the function of alarming in case accidents happened during the forming process. When the remained protection gas is not enough and reaches the alarm value, it will remind the users automatically. Adopting component system development architecture: Each functional module can be flexibly configured, which makes it easy to facilitate system upgrade and expansion.The software interface is beautiful, the operation is simple, the use is convenient and the maintenance is easy. Process design is rigorous, efficient, and safe, can monitor abnormal conditions. Support third-party data export: support text, EXCEL, ADO, SQL, dbExpress and other formats of data export. Complete fault self-recovery circuit design ensures that the equipment can work normally and prevent crashes.
