The flexibility higher of part.Traditional band large-scale metal component increasing material manufacturing system, if to shape more bulky than forming cavity zero
During part, it is necessary to a forming cavity than volume of part bigger to be formed is manufactured again, so takes longer, tedious process,
Cost is higher；And the expansible increasing material manufacturing system of the present 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, it is necessary into
Shape intracavitary is filled with not active gases such as inert gas (such as argon gas and helium) so that and the oxygen content in cavity is less than 50ppm, with
Ensure to be influenced by surrounding air in forming process.Current existing band large-scale metal component increasing material manufacturing system, it is necessary to
Substantial amounts of inert protective gas.And this expansible increasing material manufacturing system, before forming inert gas used in exhaust process
Amount can substantially reduce, and reduce production cost.
In conclusion by this increasing material manufacturing system and increasing material manufacturing method in the present invention, change in shaping ruler
The inherent shortcoming of existing forming cavity constancy of volume, substantially reduces the exhaust time during very little different part, improves production effect
Rate, reduces comprehensive production cost.
