Abstract
A method of fabricating rotary drag bits for subterranean drilling by layering techniques such as are employed in rapid prototyping technology. Thin layers of powder may be sequentially deposited and fused or otherwise bonded to define the bit body, or thin sheets of material may be stacked, bonded and cut. Bit body components may also be formed by the method, and subsequently assembled with other components made in like manner or by other methods to produce a bit body. Bits fabricated according to the method are also disclosed.
