MOLDS AND METHODS OF FORMING MOLDS ASSOCIATED WITH MANUFACTURE OF ROTARY DRILL BITS AND OTHER DOWNHOLE TOOLS
First Claim
1. A method of forming a mold operable to fabricate at least one component of a well drilling tool comprising:
- (a) using a three dimensional (3D) printer to deposit a plurality of thin layers of powder having a configuration and dimensions based on three dimensional (3D) design data associated with the well drilling tool;
(b) using the 3D printer to apply binder material to each thin layer of powder; and
repeating steps (a) and (b) to produce the mold with a mold cavity having a configuration and dimensions based on the 3D design data for the associated well drilling tool.

Abstract
Three dimensional printing equipment and techniques may be used in combination with three dimensional design data associated with well drilling equipment and well completion equipment to form molds associated with manufacture of such equipment. For example, such molds may be used to form a bit body or other components associated with a rotary drill bit. For some applications composite or matrix materials may be placed in the mold to form a matrix bit body. Heat transfer characteristics of the mold may be optimized for heating and/or cooling of the matrix materials to provide optimum fracture resistant (toughness) and optimum erosion, abrasion and/or wear resistance for portions of the bit body. Such molds may also be used to form steel bit bodies associated with fixed cutter rotary drill bits and other components associated with a wide variety of well drilling equipment and well completion equipment.
