Abstract
【選択図】図1A
Description
以下の例を参照する。これらの例は上の説明と合わせて、本発明のいくつかの実施形態を説明する(ただし本発明はこれらの例に制限されない)。
硬化工程の時間遅延と曲がりの影響との間の関係を調査するための実験を行った。この調査は、変形が最大限に減少するときの、連続する層の間の最小の時間遅延を求める目的で行った。
この例における実験は、例1に説明した実験に似ているが、230mmの棒の長さを使用し、印刷システムを最初に高速印刷(HS)モードで動作させ、次に高品質(HQ)モードで動作させた。高速印刷モードとは、物体の印刷が完了するまでの時間の長さが、通常モードよりも短い(すなわちスピーディである)ことを意味する。高品質モードとは、物体の印刷解像度が高いことを意味する。
