One-dimensional hierarchical nested channel design for continuous feed manufacturing processes

A method of forming an interface, said method comprising the steps of:

• forming a series of hierarchical channels in a first member surface of a first member using a continuous-feed manufacturing process, said channels being configured to control particle stacking;
• and
• pressing said first member to a second member with a layer of particle-filled viscous material between said first member surface and a second member surface of said second member.

A method of forming an interface, said method comprising the steps of:

• forming a series of hierarchical channels in a substantially cylindrical first member surface of a substantially cylindrical first member, said channels being configured to control particle stacking;
• and
• pressing said first member to a workpiece with a layer of particle-filled viscous material between said first member surface and a surface of said second workpiece.
