FIELD: physics.
SUBSTANCE: method of manufacturing a three-dimensional object using the origami fusen method characterizing in that inflection along the line between the side ends of one small angle and inflection along the line between the side ends of another small angle are performed on the flat preform manufactured to impart an internal volume by filling it, having four outer large angles and two oppositely located small angles.
EFFECT: improving the convenience of manufacturing three-dimensional objects, expanding the possibilities of using different materials, expanding the scope of manufacturing three-dimensional objects using the origami fusen method due to the provided opportunities to spread the flat preform made to impart an internal volume by filling it, having four outer large angles and two oppositely located outer small angles, applying forces to inflection on lines between the side ends of the small angle and the lines between the side ends of the other small angle, allowing to form the best ribs already at the expansion.
