Abstract
Description
n1sinθi=n2sinθt
ここでn1は、光線が進行する媒体(ここでは、基板230)の屈折率であり、θiは、2つの媒質間の界面への光線の入射角であり、n2は、界面の他方の側(ここでは、基板230を取り囲む空気)の媒体の屈折率であり、θtは、2つの媒質間の界面を離れる光線の角度(透過角)である。 全反射は、透過角度が90°でその正弦(sin)が1のときに発生します。したがって、臨界角θcは、以下のように定義される。
θc=θi=sin−1(n2/n1)
・印刷プロセスに適用されるアクティブ冷却のレベルを、たとえばファン速度を変えることによって調整すること
・ビルドチャンバの大気条件、例えば温度または湿度を調整すること
・印刷されるオブジェクトに適用されるプラスチックの温度を調節すること
・印刷速度を調整すること
・層の高さ、線の太さ、強度または任意の他の印刷パラメータを調整すること
・基板温度を調整すること。これはまた、機能性を維持するために対応する光源強度の調整が必要となるかもしれない。
