Or powder, the technology of metalwork is constructed by way of successively accumulating.Using electric arc as the metal 3D printing technique of heat source, printing heat
There are following features for cycle：1, in print procedure, molten bath volume is big compared with laser printing, generally in 30~100g.2, print procedure
In, arc energy is high and concentrates, and for maximum temperature up to 1700 DEG C or more, molten pool metal is in an overheated state.3, in print procedure,
Heat source is small, and implements movement, and Gu Dayinwenduchang is an extremely uneven temperature field.
It is gained knowledge from metal it is found that under conditions of metal material chemical is certain, the crystallization condition of material is (i.e. high
Warm residence time, cooling velocity) determine the interior tissue of material, and then determine the physicochemical property of material.Therefore temperature controls
It is the key that ensure printing metallicity.
Electric arc persistently provides high heat in print procedure, such as interlayer temperature will be made to be up to 350 DEG C or more without cooling,
So cause molten pool metal high-temperature residence time long, cooling velocity is slow, and interior tissue is coarse, and material property deteriorates.It is required that general
The print temperature of carbon steel printing must not require higher than 300 DEG C；The print temperature of stainless steel must not be higher than 150 DEG C；It is steel alloy, resistance to
The print temperature of hot steel, which must not require, is higher than 250 DEG C, and preheating temperature is generally not less than 100 DEG C.

Method controls, and printing effect is low, and repeatedly stops to cause the increase of connector quantity, and material property declines.
When using back side water-cooling method, influence of the water variation to temperature is huge, water difficulty tune, and directly uses water cooling,
Cooling velocity is too fast, and it is minimum to connect range to cooling velocity tune.And cooling water is caused air humidity to add by thermal evaporation in cooling procedure
Greatly, print quality and working environment are seriously affected.
