Abstract
A method of electrolytic additive manufacturing provides 3-D parts. The method can be used to form parts from particulate material in an electrolytic bath. Metal is electrolytically deposited, binding the particles. Layers of the particles are built up to form the parts. The same process can be used to form parts without the particulate material. Layers of metal are electrolytically deposited in the electrolyte bath to form the parts.
Claims10
A method of forming a 3-D structure, comprising:
- depositing a voxel or layer of metal in an electrolyte bath on a substrate by:
- depositing a powder to form a layer of particulate material that covers said substrate,
- moving said substrate relative to an electrode according to an electrode path based on a model of the 3-D structure, and
- applying a localized electric field between said electrode and said substrate as said substrate is moved to selectively electrolytically deposit a metal binder present in said electrolyte bath on said layer of particulate material, said metal binder selectively binding said particulate material only where said metal binder is deposited to form said voxel or layer of metal;
- and
- separating said electrode from said voxel or layer of metal and repeating said steps of depositing said powder to form another layer of particulate material that covers one or more previously formed voxels or layer of metal, moving said substrate, and applying said localized electric field multiple times to deposit multiple metal voxels or layers of metal binding said particulate material, thereby forming the 3-D structure without the use of a mask.
