Abstract: The device of selective electro-deposition rapid
prototyping with electrolyte jet is found and the fundamental
experiments are achieved with it. The experimental results show that the
three-dimensional part of metal copper can be formed with this
technology. The size precision and shape precision of the part deposited
part are acceptable and the thickness of it is up to 1.2 mm. The
analyses with SEM and XRD show that lots of pores are distributed on
whole deposited layer symmetrically. The grain size of crystal is 10～15
nm, high break strength and high hardness of it are obtained in
mechanical properties measuring.
Key words: Rapid prototyping Electro deposition Nanocrystalline copper
