Description
積層造形システムは、層毎の三次元物体の生成を可能にする。
積層造形、高速な製品試作または固体自由形状製作とも呼ばれる三次元(3D)印刷は、多種多様な物体を製造するための技術である。幾つかの積層造形システムは、粉末状構築材料のような構築材料の逐次の層の選択的な固化を通じて三次元物体を生成する。係るシステムの幾つかは、構築材料の層に薬剤を選択的に付着することにより、構築材料の部分を凝固させることができる。幾つかのシステムは、例えば液体結合剤が塗布された構築材料を化学的に凝固させるための液体結合剤を使用することができる。
−手押し車106の構築材料体積110へ充填された構築材料の特性、
−UCRユニット104のミクサ162により供給される際に新しい粉末と中古の粉末の混合比、
−構築材料体積110内の粉末の充填レベル、
−UCRユニット104との相互作用の完了後の手押し車106内の機械的構成要素の位置、例えば図2の例に示されたような構造体を有する手押し車を考察する場合、構築プラットフォーム122の垂直位置に関する情報がメモリに含められ得る。
−構築された物体/部品の幾何学的特性。これは、UCRユニットにおいて開梱プロセス154及び冷却プロセス166を制御するために有用であることができる。開梱プロセス154は、構築体積および構築された物体に如何にしてアクセスするかの知識を取得することができ、冷却プロセス166は、冷却時間または冷却速度を決定することができる。
−図2の例で説明されたような手押し車の場合、構築体積の体積V2、
−構築供給部体積に残っている未使用粉末、
−構築の時間、
−3D印刷物体のアニーリング及び/又は冷却を制御するためにUCRユニット104の冷却プロセス166により使用され得る印刷モードパラメータ。
