Method to construct and physically join building blocks into a near-net shaped part using an interfacial reaction-activation mechanism
First Claim

1. A method of manufacturing a machinery part, comprising:
- modeling the part as data capable of being manipulated by a computer;
using the computer to transform the data into a format wherein the machinery part is represented as a near-net structure made from channel-shaped building blocks;
wherein the building blocks are of uniform shape and each building block is a single piece of material and has a shape that is entirely that of an open three-sided or two-sided channel having flat sides;
wherein each building block is at least partially coated with a reactive coating that also has an adhesive property, such that flat sides of building blocks adhere upon contact to each other when and may thereby be interfacially adjoined;
delivering the data to an automated stacking system;
using the stacking system to assemble the building blocks, using only gravity or the adhesive property of adjoining flat sides for support, to form the near-net structure;
wherein the near-net structure is assembled with a stacking process that requires no internal or external support other than the building blocks themselves to support the assembly;
fusing the building blocks with a reaction-activation process, such that the reactive coating causes any adjoining flat sides of the building blocks to be fused together;
wherein the building blocks have a surface precursor, and the step of fusing the building blocks is performed by activating the precursor; and
removing excess material from the near-net structure to form the machinery part.
