Free casting method, free casting apparatus, and casting

A free casting method which is capable of obtaining castings without using casting moulds, including:

• a lead-out step for leading out molten metal from its surface level to retain itself temporarily by a surface film generated on an outer surface or surface tension, in which the molten metal is supplied to retained molten metal through the surface level;
• and
• a forming step for obtaining a formed body by solidifying the retained molten metal led out along a set passage depending on a desired casting shape,
• wherein the retained molten metal is solidified after being formed into the desired shape by applying an external force thereto at positions between an unrestrained root portion of the retained molten metal in vicinity of the surface level of the molten metal and a solidification interface defined as a boundary between the retained molten metal and the formed body in the forming step.
