Abstract
A three-dimensional image forming system according to the present invention includes a conveying unit which conveys a heat-expandable sheet along a conveyance path, a heating unit which heats the heat-expandable sheet by irradiating the heat-expandable sheet with light, and a control unit which preheats the surroundings of the heating unit to a previously determined preheat temperature and then causes the conveying unit to convey the heat-expandable sheet.
Claims12
A three-dimensional image forming system comprising:
- a conveyance path along which a heat-expandable sheet is conveyable;
- a heater which heats the heat-expandable sheet by irradiating the heat-expandable sheet with light;
- and
- a computer comprising a processor and a memory, the computer being configured to:
- perform control to increase a temperature of surroundings of the heater to a heating temperature higher than a predetermined preheat temperature, and then to decrease the temperature of the surroundings of the heater to the preheat temperature, and thereafter, perform control to cause the heat-expandable sheet to be conveyed along the conveyance path;
- perform control to form a three-dimensional image by causing the heat-expandable sheet to be conveyed and causing the heater to perform light irradiation;
- and
- upon completion of the formation of the three-dimensional image, perform control to cause the heater to stop the light irradiation to decrease the temperature of the surroundings of the heater which has increased to a formation temperature higher than the preheat temperature by the light irradiation during the formation of the three-dimensional image,
- wherein, in response to placement of a next heat-expandable sheet being detected before the temperature of the surroundings of the heater decreases to a predetermined end temperature lower than the preheat temperature, formation of a next three-dimensional image is continuously performed.
