Provided is a multi-shank heater to be mounted on a support substrate, wherein, with a normal direction relative to the support substrate, which is a direction from the heater side toward the support substrate side, as a basis, the multi-shank heater has U-shaped pieces in which an angle θ of a planar direction of the U-shaped pieces, which is a direction from the heater side toward the support substrate side, is ±10° or more and ±60° or less. An object of the present invention is to provide a multi-shank heater capable of considerably improving the energy output even when the U-shaped pieces are arranged in a high density and have the same pitch.

Abstract

A production method of an additive manufactured object is provided. The method is an EB-based additive manufacturing method of spreading a pure copper powder, preheating the pure copper powder and thereafter partially melting the pure copper powder by scanning the pure copper powder with an electron beam, solidifying the pure copper powder to form a first layer, newly spreading a pure copper powder on the first layer, preheating the pure copper powder and thereafter partially melting the pure copper powder by scanning the pure copper powder with an electron beam, solidifying the pure copper powder to form a second layer, and repeating the foregoing process to add layers. The pure copper powder is a pure copper powder with a Si coating formed thereon, and the preheating temperature is set to be 400° C. or higher and less than 800° C.
