PRODUCTION METHOD OF SOLID ARTICLE, SOLID ARTICLE, SOLID ARTICLE PRODUCTION SUPPORT APPARATUS AND SOLID ARTICLE PRODUCTION SUPPORT PROGRAM

To provide a solid article production method capable of easy and high-speed production of solid articles having high strength.SOLUTION: The production method of solid articles contains: a step of sandwiching and laminating an intermediate sheet 26 between a first resin sheet 16 and a second resin sheet 18 and arranging the intermediate sheet 26 in a main region in the inside of the circumferences 29,30 of the first resin sheet 16 and the second resin sheet 18 and in a part of an entrance region of a site between the circumferences 29,30 which are continuous with the main region; a step of joining the circumferences 29,30 together, excluding a part of the region, by heating to make the entrance region of the circumferences 29,30 become a gas entrance 4; a step of introducing a gas from the gas entrance 4 to an area between the first resin sheet 16 and the second resin sheet 18 to form a clearance part 3 between the first resin sheet 16 and the second resin sheet 18; and a step of cooling with the clearance part 3 having been provided for solidification of the first resin sheet 16 and the second resin sheet 18.SELECTED DRAWING: Figure 3 【課題】強度のある立体物を簡易かつ高速に製造可能な立体物製造方法を提供する。【解決手段】第１樹脂シート１６と第２樹脂シート１８との間に中間シート２６を挟んで積層して、中間シート２６を、第１樹脂シート１６及び第２樹脂シート１８の周縁２９、３０よりも内側の主領域、及びその主領域に連続する周縁間２９、３０の領域の一部の入口領域に配置するステップと、加熱により、周縁２９、３０同士を一部の領域を除いて接合させて、周縁２９、３０の入口領域を気体入口４とするステップと、気体入口４から第１樹脂シート１６と第２樹脂シート１８との間に気体を導入して、第１樹脂シート１６と第２樹脂シート１８との間に間隙部３を設けるステップと、間隙部３を設けた状態で冷却して、第１樹脂シート１６及び第２樹脂シート１８を固化するステップと、を含む、立体物の製造方法。【選択図】図３
