Forming method and formed article

A method for forming an article, the method comprising:

• forming a first part of the article to include a substrate portion and an eaves portion by depositing a plurality of layers in a stacked arrangement, the first part comprising a first metal;
• forming a second part of the article by depositing a plurality of layers in a stacked arrangement such that the second part supports the eaves portion, the second part comprising a second metal, wherein the eaves portion overhangs the second part such that the second part supports the eaves portion after the first part and the second part are formed;
• sintering the first metal and the second metal;
• and
• removing the second part from the article by immersing the article in an electrolyte solution and causing a current to flow in the second part, wherein the removal of the second part causes the eaves portion to overhang a space where the second part was located prior to the removal of the second part, the space being open,
• wherein when a long side of an upper surface of the first part is set to an X direction in the Cartesian coordinate system, a short side of the first part is set to a Y direction in the Cartesian coordinate system that crosses the X direction, and a thickness direction of the first part that crosses the X and Y directions is set to a Z direction in the Cartesian coordinate system, the eaves portion extends from the substrate portion in the X direction and the space is defined as being in the Z direction beneath the eaves portion such that a step in the Z direction is formed at a transition between the substrate portion and the eaves portion.
