Description
装置内部で空気を循環させることにより、さまざまな問題を解決できる。1つの特定の問題は空中浮遊している粉末、つまり飛散した粉末であり、これによりプリンタ機構および電子構成部品が汚染され、結果的に装置の信頼性が低下する。また、粉末は装置の上蓋内部に堆積し、結果的に装置動作を監視するオペレータ能力を低下させる。
図4Aは、単色および多色モードの両方で高速プリントするのに特に適している高速プリント3次元プリンタの構成部品を示す。キャリッジ85が往復運動するようにガントリ40に取り付けられている。キャリッジ85は、レール86上でy軸(高速軸)に沿って往復運動できる。図4Bには、上蓋を閉じた状態のキャリッジ85、およびガントリ40が、結合剤コンジット87と共に示されている。図4Cは上蓋を開いたキャリッジ85を示している。
造形速度を最大化することは、ユーザの重要な関心事項である。造形時間は2つの主要な要素、すなわち粉末の拡散と結合剤溶液の堆積とを有する。粉末の拡散速度はいくつかの要因で制限される。これら要因には、平滑な表面層の維持および飛散粉末量の最小化を必要とすることが挙げられる。したがって、造形速度を増加させる1つの方法は、結合剤の堆積速度を増加させることである。結合剤の堆積速度を増加させる1つの方法は、複数のプリントヘッドを利用することである。
カラーのインク・ジェット・プリントヘッドをプリンタに組み込むことにより、様々なカラーまたはインクをプリントする能力を提供できる。システムはこれらのプリントヘッドを利用して液体結合剤を堆積させるため、これらプリントヘッドにより、多孔質材料を結合させる材料としてカラー結合剤を堆積できる。特に、粉末材料はホワイトまたは無色であり、インクを吸収して粉末に色を付けることができる。結果的に、本発明の実施形態は、実質的にフルカラーの3次元造形物を造形し、造形物全体にわたって色を変化させることができる。
図11Aは圧力制御されたコンジット87A−145Dにより供給されるプリントヘッド145A−145Dのシステムの概略ブロック図である。図に示すように、結合剤供給システムは複数のプリントヘッド145A、145B、145C、145Dを含み、これらプリントヘッドは、複数の結合剤供給リザーバ175、112、114、116および廃液収容器155に接続されている。図のように、イエロー結合剤供給リザーバ112はイエローに指定されたプリントヘッド145Bに接続され、マゼンタ結合剤供給リザーバ114はマゼンタに指定されたプリントヘッド145Cに、またシアン結合剤供給リザーバ116はシアンに指定されたプリントヘッド145Dに接続されている。透明結合剤供給リザーバ175は透明色に指定されたプリントヘッド145Aおよび色の指定されたプリントヘッド145B、145C、145Dのそれぞれに接続されている。すべてのプリントヘッド145A〜145Dは廃液収容器155に接続されている。詳細は以下に述べる。
3次元物体の模型を製作する方法および装置を、その特定の実施形態に関して図示し、説明してきたが、当業者には、添付の特許請求の範囲に定義された本発明の精神と範囲から逸脱することなく、形態または細部に各種の変更を加えるのが可能であることは理解されるであろう。これらおよび他のすべての均等物も特許請求の範囲に包含されるものとする。
