Abstract
A powder convergence improves without varying the flow velocity and powder density of a powder flow. A processing nozzle includes an inner cone including a beam path that passes light from a light source, an outer cone arranged outside the inner cone, a fluid ejection channel formed by a gap between the inner cone and the outer cone, and including an ejection port that opens toward a process surface, and a fluid guide channel having a flow inlet for a fluid. The fluid guide channel guides the fluid toward the fluid ejection channel in a direction away from the beam path.
