Description
米国政府は、ローレンスリバモア国立研究所の運営のために、米国エネルギ省とローレンスリバモアナショナルセキュリティLLCとの間の契約番号DE-AC52-07NA27344に従って、本発明において権利を有する。
本開示は、付加製造を実行するためのシステムおよび方法に関し、より詳細には、コンピュータ断層撮影(CT)技術を使用する体積製造(volumetric fabrication)に向けられたシステムおよび方法に関する。
ターゲットの3D部分ジオメトリと、計算された投影との間の関係を理解するために、図1Aならびに図1B-1Dの座標系指定を考慮する。以下の議論に関して、グローバルデカルト座標系(x、y、z)を採用して、3Dビルド体積と、考慮される投影の角度θに向きが依存する回転されたデカルト座標系(x’、y’、z’)とを参照することが便利である。これらの座標系では、zは、体積10のまわりの角度θでの曝露の方位角的アレイ化のための軸である。各角度θに関して、投影が計算される。特定の角度θで、ターゲット体積内で生成される3次元強度マップIθ(x、y、z)を完全に決定する2次元関数Pθ(y’、z)として、投影を定義する(Pθは角度θに依存するが、2つの空間的次元を有するので、2次元関数と呼ばれることに留意すべきである)。最も単純なケースでは、投影は、樹脂体積をx’方向に伝播する(y’、z)ドメインの2次元イメージと考えられ得る場合がある。この理想的なケースでは、投影によって生成された3D強度プロファイルは、x’方向にターゲット体積を通して押し出された(y’、z)ドメインイメージのように見える。この近似は、照明投影がコリメートされる場合、物理的に良好に有効である。医療イメージング用途では、これは、平行ビーム断層撮影に類似する。本開示に関して、これは、光学的構成が長い焦点深度(特に、現在のSLM技術で利用可能な小さな回折角に関連する)を有するときはいつでも、十分に良好な近似である。一般的なケースでは、光の伝搬および減衰モデルは、特定の角度で2D投影関数から生成される3D強度マップを表す。この説明と図1Aでは、本方法の説明を簡単にするために理想的なケースを考慮する。
