METHOD FOR PRODUCING CERAMIC MOLDING
To solve the problem that, in a powder floor melting-coupling method for obtaining a ceramic molding, the molding has been made amorphous in a state in which pre-heating is not present, and crystalline substance has not been obtained.SOLUTION: There is provided a method for producing a ceramic molding which includes the steps in which (i) ceramic powder is leveled to form a powder layer, (ii) the powder layer is irradiated with a laser beam on the basis of three-dimensional data to crystallize the irradiated part, and (iii) the step (i) and the step (ii) are repeatedly performed to produce a ceramic molding. In the step (ii), the surface of the powder layer is irradiated with the laser beam in a non-focused state.SELECTED DRAWING: Figure 3
【課題】セラミックス造形物を得るための粉末床熔融結合法において、予備加熱の無い状態では造形物が非晶質化してしまい、結晶質が得られていなかった。【解決手段】（ｉ）セラミックス粉末を均し、粉末層を形成する工程と、（ｉｉ）前記粉末層に対し三次元データに基づいてレーザービームを照射し、照射部位を結晶化させる工程と、（ｉｉｉ）前記（ｉ）、（ｉｉ）の工程を繰り返し行い、セラミックス造形物を製造する方法であって、前記（ｉｉ）の工程において、前記レーザービームを前記粉末層の表面に対し非合焦な状態で照射することを特徴とするセラミックス造形物の製造方法。【選択図】図３
