Electrochemical fabrication methods using transfer plating of masks

This process builds three-dimensional objects layer by layer. Each layer is made by depositing material through openings in a temporary mask. The mask is created by transferring a patterned precursor material onto the surface, which is then transformed into the final mask. The process further specifies depositing a seed layer before the main material and then planarizing the deposited material and mask before removing the mask.

Why it matters: Filed before the boom in additive manufacturing, particularly for micro-scale and multi-material structures. The intervening two decades have seen significant advancements in precision patterning and electrochemical deposition, making this layer-by-layer fabrication method more practical and relevant for complex designs.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: SpecializedElectrochemical deposition, precision mask patterning, planarization
