Apparatus and system for manufacturing tool crowns using additive manufacturing |
| abstract |
A tool includes a base having a crown extending from the base. The crown is additively fabricated on the base, forming a joint between the crown and the base. At least one protrusion may extend from the base surface into the recess in the crown such that the crown surrounds the protrusion. The protrusions can mechanically interlock the base and crown to improve torque transfer between the crown and the base. The junction at the contact between the base and the crown may comprise at least a portion of the crown impregnated with material of the base, or at least a portion of the base impregnated with material of the crown, which may improve crown to base the connection between. |
