Abstract
Description
a.上記による付加製造用組成物の物体を流動性のある状態で準備するステップと、
b.付加製造用組成物の物体の少なくとも一部に照射することで付加製造用組成物の物体の照射された部分を共連続二相構造体へと相分離させ、付加製造用組成物の物体の照射された部分における共連続二相構造体の形成を可能にし、それにより、製造すべき未焼成体の少なくとも一部を形成するステップであって、1つの連続相が、少なくとも1種以上の重合した有機ポリマー前駆体化合物によって実質的に形成され、1つの連続相が、少なくとも1種以上のアルコキシル化無機前駆体化合物によって実質的に形成されるステップと、
c.任意選択的に、未焼成体が形成されるまで、好ましくは異なる組成物を使用する単一の層内で、又は異なる組成物を使用する複数の層で、1つ前のステップを1回以上繰り返すステップと
を含み、未焼成体を焼成して物品を製造するステップは、
d.重合した有機ポリマー前駆体化合物及び/又は光重合性有機ポリマー前駆体化合物を除去するのに十分な温度で未焼成体を焼成して、ガラス、セラミック、又はガラス−セラミックの物品を形成するステップ
を含む、方法を提供することである。
樹脂組成は、成分の重量パーセントで定義される。特に記載がない限り、全ての化学物質はSigma-Aldrichから購入し、供給されたままの状態で使用した。リン酸トリエチル(TEP)、ホウ酸トリメチル(TMB)、ポリ(ジエトキシシロキサン)(PDEOS)は試薬グレードであり、湿度管理されたキャビネットで保管した。PDEOSはABCRから供給されたものであり、48〜52重量%SiO2相当であった。アクリレートモノマーであるウレタンジアクリレート(UA(DSM Coating ResinsのNeorad U25−20D)及びトリプロピレングリコールジアクリレート(TPGDA)は、重合禁止剤4−メトキシフェノール(MEHQ)と共に使用した。この重合禁止剤は、デジタル光プロジェクション(DLP)3D印刷に必要な酸素阻害に不可欠な役割を果たすためである。適正な垂直解像度を得るために、青色光吸収染料であるSudan Iを樹脂の総含有量に対して0.005重量%で添加した。光開始剤であるジフェニル(2,4,6−トリメチルベンゾイル)ホスフィンオキシド(TPO)は樹脂の総含有量に対して1.0重量%で添加した。樹脂1〜5の組成は以下の表S1に記載されている。得られた樹脂は水と同等の粘度を有しており、混合直後に使用した。
3回蒸留した水の中に65重量%のエタノールと0.1重量%のHNO3が入っている加水分解溶液3gの中に、9.58gのTEOSを最初に溶解させ、その後これを約30分撹拌することにより20gのゾル−ゲルインクを製造した。続いて、0.054gの光開始剤であるジフェニル(2,4,6−トリメチルベンゾイル)ホスフィンオキシド(TPO)及び1.06gのAPTMSを溶液に添加し、さらに30分間撹拌して確実に完全に溶解させた。その後、3回蒸留した水の中に65重量%のエタノールが入っている溶液6.2gに0.094gの酢酸アンモニウムを溶解させ、これを溶液に添加して混合物を形成し、これを再度撹拌して全ての成分を完全に混合した。
