4. Conclusions
The nozzle with large caliber can increase the electroforming speed. The nozzle with heavier caliber
results in a larger dimension of casting plaque which is 2 times of that of nozzle. This explains why the
forming accuracy of parts is greatly going in the down side. The practically formed casting thickness is
not just simple superimposition between layers. It is also influenced by electrical field distribution in the
deposition process. During the course of electroforming the thickness distribution of casting is not equal,
reach maximum in the center and gradually turn thinner while far apart, exhibiting exponential function
distribution. For the sake of obtaining smooth deposited layer the scanning interval of L≤0.5d (nozzle
caliber ) is preferable.
