Abstract
Description
ステップ1:開始。
ステップ2:図14に示されるように、物体68をタンク48の底部から離れるように移動させる。
ステップ3:図15および図16に示されるように、形成されている物体68の底部88と間隙80との間の間隔86に樹脂が流れ込む際に、一時的に光を放出しない。
ステップ4:図17に示されるように、形成されている物体68の底部88と間隙80との間の間隔86を樹脂70が充填する際に、形成されている物体68の所望の断面を形成するように樹脂を硬化させるために光を放出する。
ステップ5:ステップ2を繰り返す。
湿潤性材料56は、ヒドロゲル、例えばシリコーンヒドロゲル、または、任意の他の適した湿潤性材料であってよく、これによって、図21〜図29に示されるように、タンク42において、湿潤性材料56と樹脂との間の界面での間隙80または「不感帯」が生じる。間隙80によって、タンク42における、湿潤性材料56と樹脂との間の反発作用の分子間力が生じ得る、および/または、樹脂および水は混和しないため、間隙80によって湿潤性材料56および樹脂を分離する水の層が生じ得る。湿潤性材料56と樹脂との間の分離は、グリセリンは樹脂と混和しないためグリセリンを湿潤性材料56に加えることによって改良可能である。湿潤性材料56と樹脂との間の分離は、紫外線抑制剤およびグリセリンを湿潤性材料56に加えることによって、さらに改良できる。紫外線抑制剤およびグリセリンを加えることによって、湿潤性材料56との間の界面における樹脂の非常に薄い層の硬化を防止する。
湿潤性材料56において使用されるヒドロゲルは、任意の手段によって調製されてよいが、以下の一般的な手段が典型的である。
グリセリンベースのゲルは、用途の熱的要件に従って変化させるグリセリンのwt%でグリセリンの水溶液中に調製可能である。湿潤性材料は、樹脂をはじき、かつ高温に耐えることができるグリセリンゲルであってよい。
