The flexibility of part is higher.Traditional band large-scale metal component increasing material manufacturing system, if to shape more bulky than forming cavity zero
When part, it is necessary to a forming cavity bigger than volume of part to be formed is manufactured again, is taken a long time in this way, process is tedious,
Higher cost；And expansible increasing material manufacturing system of the invention, can neatly modularization extension forming cavity volume, reach into
The size requirement of shape part.
(3) can significantly saving and protection gas usage amount.Before laser gain material manufacturing process starts, need at
Shape is intracavitary to be filled with not active gases such as inert gas (such as argon gas and helium), so that the intracorporal oxygen content of chamber is lower than 50ppm, with
Guarantee to be influenced by surrounding air in forming process.Current existing band large-scale metal component increasing material manufacturing system, needs
A large amount of inert protective gas.And this expansible increasing material manufacturing system, before forming inert gas used in exhaust process
Amount will be greatly reduced, and reduce production cost.
In conclusion this increasing material manufacturing system and increasing material manufacturing method in through the invention, change in forming ruler
The inherent shortcoming of existing forming cavity constancy of volume, substantially reduces the exhaust time when very little different part, improves production effect
Rate reduces comprehensive production cost.
