Abstract
Description
本発明は、アディティブ法造形技術を用いた三次元物体の製造に関する。より詳細には、本発明は、所定のパターンで凝固可能な材料を堆積させることによる三次元物体の形成と、このような三次元物体を作製する際にその一部を支持するための支持構造の提供とに関する。
[発明の簡単な概要]

<実施例>
以下、本発明を実施例の中でより具体的に説明するが、これらは例示のものとしてのみ意図され、本発明の範囲内の多数の修正形態および変形形態が当業者にとっては明らかであろう。明記する場合を除いて、以下の実施例で報告する全ての部品、パーセンテージ、比率は、重量基準であり、実施例内の全ての試薬は、ミズーリ州セントルイスのシグマアルドリッチ化学会社等の一般的な化学製品供給業者から得られ、または購入可能であり、あるいは従来からある技術によって合成されてもよい。
<実施例I>
アルカリ可溶性熱可塑性材料は、74%のベースポリマーと、26%のブチルフェニルジフェニルホスフェート可塑剤とを含有する。ベースポリマーは、メタクリル酸とメタクリル酸メチルとの高分子量および低分子量の共重合体からなる。ベースポリマーは、およそ50%の高分子量共重合体と50%の低分子量共重合体とを含有し、それぞれプラスマイナス5%である。各共重合体では、重量%比1:2のメタクリル酸とメタクリル酸メチルとを含有する。高分子量共重合体は高粘度(低メルトフロー)という特徴を有し、低分子量共重合体は低粘度(高メルトフロー)という特徴を有する。共重合体のメルトフローは、各共重合体を26重量%のブチルフェニルジフェニルホスフェート可塑剤を用いて別々に可塑化することにより計測される。可塑化された高分子量共重合体のメルトフローインデックスは、230℃での1.2キログラムの荷重下においてASTM D1238に準拠して測定すると、0.4グラム/10分から0.8グラム/10分の範囲内である。可塑化された低分子量共重合体のメルトフローインデックスは、28グラム/10分から35グラム/10分の範囲内である。結果として生じる熱可塑性組成物は、5グラム/10分から6.5グラム/10分のメルトフローインデックスと、約90℃のガラス転移温度とを有する。
<実施例II>
アルカリ可溶性可塑性材料は、79%(+/−5%)のベースポリマーと21%(+/−5%)のブチルフェニルジフェニルホスフェート可塑剤とを含有する。ベースポリマーは重量%比1:1のメタクリル酸とメタクリル酸メチルとから成り、135,000グラム/モルの分子量を有する。ベースポリマーを可塑剤に混ぜ合わせる前に、ベースポリマーは、ポリマーから水分を除去するために220℃のオーブンにおいて低圧で加熱される。10〜15時間の低圧での加熱が、ベースポリマーを乾燥させるために十分であると認められた。結果として生じた乾燥ポリマーは粒状の形態であり、可塑剤と共に周知の方法で撹拌機に供給される。結果として生じるアルカリ可溶性熱可塑性材料は、230℃での1.2キログラムの荷重下においてASTM D1238に準拠して測定したところ、5グラム/10分から6.5グラム/10分の範囲のメルトフローインデックスを有する。アルカリ可溶性熱可塑性材料のガラス転移開始温度は約101.5℃であり、ガラス転移最高温度は約111℃である。
<実施例III>
アルカリ可溶性熱可塑性材料は上述の実施例IIの場合と同じ組成物を有するが、この実施例では、水分を除去するためのベースポリマーの加熱は行われない。実施例IIの場合と同様に、アルカリ可溶性熱可塑性材料は、加工され、Stratasys FDM(登録商標)機から押し出され、そして堆積させられる。これにより、ABS熱可塑性剤で作製された造形物の支持構造が形成される。この実施例では、アルカリ可溶性熱可塑性材料が、押出ヘッドから適正量よりも多量の「滲出」を示したが、それ以外では、三次元造形に好適な特性を示した。「滲出」は組成物内に存在する水分に起因する。もし、材料ディスペンサが積極的な分離機構を有する造形システムで使用されれば、Stratasys FDM(登録商標)機内で示された「滲出」作用は生じないであろうし、この実施例IIIにかかる材料を有効に利用することができる。
<実施例IV>
可塑剤のガラス転移温度およびメルトフローインデックスへの影響を比較するために、種々の濃度の可塑剤を有する本発明のアルカリ可溶性熱可塑性材料の試料が作成された。用いられたベースポリマーおよび可塑剤は実施例Iで述べたものと同じである。表1は、実施例IV(A)〜実施例IV(M)のアルカリ可溶性熱可塑性材料の重量%濃度を示す。表に示すように、実施例ごとに可塑剤の濃度に変化を持たせた。表1は、さらに、実施例IV(A)〜実施例IV(M)のアルカリ可溶性熱可塑性材料の、対応するガラス転移温度(Tg)とメルトフローインデックス(MFI)とを示す。メルトフローインデックスは、160℃、230℃、または270℃での1.2キログラムの荷重下においてASTM D1238に準拠して試験された。
