Description
層毎に3次元物体を生成する積層造形システムは、3次元物体を作成するための潜在的に好都合な方式として提案されている。
有形の3次元物体を生成するプロセスは、構築材料の層を形成し、構築材料の層の表面の少なくとも一部に薬剤(例えば、合体剤および/または合体改質剤、又は別の薬剤)を選択的に供給し、構築材料の層にエネルギーを一時的に印加することを含む一連の段階を含むことができる。エネルギーの一時的な印加により、構築材料および合体剤が合体し始める点の上で、薬剤が供給された又は浸透した構築材料の部分が熱くなることができる。この温度は、溶融温度と呼ばれ得る。冷却の結果、合体した部分は、固体になり、生成されている3次元物体の一部を形成する。次いで、これらの段階は繰り返されて、3次元物体を形成することができる。また、他の段階および手順も、このプロセスと共に使用され得る。
I(x,y)=Ix(t)+Iy(t)
ここで、Ix(t)及びIy(t)はそれぞれ、上側および左側プロファイルに対応する。
IZone(x,y)=Ix,Zone(t)+Iy,Zone(t)。
