POWDER FOR CERAMIC SHAPING, CERAMIC SHAPED ARTICLE, AND METHOD FOR MANUFACTURING THE SAME
To provide: a powder for laser shaping that is capable of stable shaping and makes it possible to obtain a three-dimensional shaped article with ensured shaping precision; and a method for using the powder for laser shaping.SOLUTION: A powder for ceramic shaping is for obtaining a shaped article by repetition of successive sintering or melting and solidification of the powder by a laser light irradiation unit, wherein: the powder includes a plurality of compositions; at least one composition from among the compositions is an absorbent body that shows relatively higher absorption of the laser light than the other compositions; and at least part of the absorbent body is changed in response to irradiation with the laser light into another composition with a relatively lower rate of absorption of the laser light. A method for using the powder is also provided.SELECTED DRAWING: None
【課題】安定した造形が可能で、造形精度が確保された三次元造形物を得ることができるレーザー造形用粉体およびその使用方法を提供する。【解決手段】レーザー光の照射部における粉体を逐次焼結または溶融して凝固させることを繰り返して造形物を得るためのセラミックス造形用粉体であって、前記粉体は複数の組成物を含み、前記組成物の少なくとも１種類の組成物が、他の組成物より前記レーザー光に対し相対的に高い吸収を示す吸収体であり、前記レーザー光の照射により前記吸収体の少なくとも一部が前記レーザー光に対する吸収が相対的に低い他の組成物へ変化することを特徴とする粉体、および前記粉体を使用することを特徴とする粉体の使用方法。【選択図】なし
