The electroforming process
Electroforming is an additive manufacturing process specialized for the production of high precision metal parts. Its uniqueness is that you can grow metal parts atom by atom, providing accurate and high aspect ratios. An electrolytic bath is used in this process to deposit metal (nickel, gold, copper) onto a conductive patterned surface; this can be steel or glass. The electroformed part can be harvested from the mandrel, once the material is plated in the desired thickness.
The electroforming process allows extreme precise duplication of the mandrel. The high resolution of the conductive patterned substrate allows finer geometries, tighter tolerances and superior edge definition. This results in perfect process control, high quality production and very high repeatability. This makes electroforming perfect suitable for low cost production and high volumes.
