前記データ送信手段は、前記n個の送信データのうちi番目(ただし、iはn未満の自然数)の送信データが削除されたことを示す削除信号を前記削除信号受信手段によって受信したことを確認してから、前記n個の送信データのうちi+1番目の送信データを前記立体造形装置に送信するよう構成されたことを特徴とする。
上記(5)に記載の立体造形システムによれば、積層される造形材の単一層内であっても造形データを分割制約条件に従って分割することにより、造形データ全体が造形データ送信側の意に反して複製されることを一層抑制するとともに、立体造形物の破損を抑制することができる。
図3は、幾つかの実施形態に係る造形データの分割手法を説明するための図である。幾つかの実施形態に係る分割手段10は、図3に示すように、立体造形物に対応する造形データを、積層される造形材の1層単位に分割するよう構成される。すなわち、分割手段10は、n個の送信データの各々が立体造形物を構成する各層に対応するように(第i送信データが立体造形物のi層目に対応するように)造形データを分割する。この場合、データ送信手段12は、立体造形物のi層目に対応する第i送信データが削除されたことを示す削除信号を削除信号受信手段14によって受信したことを確認してから、立体造形物のi+1層目に対応する第i+1送信データを立体造形装置2のデータ受信手段16に送信するよう構成される。これにより、造形データが細分化され、造形データ全体が造形データ送信側の意に反して複製されることを一層抑制することができる。
このように、立体造形物に対応する造形データを、積層される造形材の複数層単位に分割することにより、1層単位に造形データを分割する場合に比して、立体造形物一個当たりの送信データの送信回数を低減することができる。
