New Technology for Rapid Prototyping and Electrodeposition with Friction

Because of the defects such as the easily produced tumors and the burrs on the electrodeposition surface during the electrodeposition process,friction assistive device was added in it and a kind of electrodeposition rapid prototyping technology that based on discrete/accumulation theory was proposed.The new technology is the core principle of rapid prototyping technology and can directly deform the metal parts simply,quickly and with low cost.Copper electrodeposition experiments show that the real-time dynamic friction closing to the cathode surface can effectively remove adsorption bubbles and tumors of the electrodeposition surface and obtain a smooth and bright surface for the electroforming layer;the rapid prototyping of friction electrodeposition technology takes the advantages of both the electroforming technology and the rapid prototyping technology,so the complexity of equipments and the cost of the parts can be effectively reduced and the precise metal parts with complex shapes,compact and homogeneous structure can be directly and quickly created.
