The invention discloses a planetary electrode discharge additive and subtractive material device and method, and relates to the technical field of electric spark deposition. The bottom end of the stirring head is hemispherical, a feeding cavity is formed in the stirring head, a feeding opening is formed in the bottom of the side wall of the stirring head, and a feeding pipe is arranged at the top end of the stirring head; the first driving mechanism is used for driving the stirring head to rotate; the stirring head penetrates through the planet carrier, a gap is formed between the planet carrier and the stirring head, the axis of the stirring head is parallel to or coincides with the axis of the planet carrier, the planet carrier is arranged in the shell, and the planet carrier is in running fit with the shell through a bearing; an air supply cavity is formed in the planet carrier, and an inflation pipe is arranged at the top end of the planet carrier. The second driving mechanism is used for driving the plan
