Description
図1は、実施形態に係る付加製造装置の一例を示す概要図である。図1に示す付加製造装置1は、一層ごとに造形物を形成する装置である。付加製造装置1は、回転体10と、回転駆動部20と、供給部30と、第1駆動部40と、平坦部50と、第2駆動部60と、照射部70と、コントローラ100とを備える。付加製造装置1は、回転駆動部20により回転する回転体10の内周面11上に一層ごとに造形物を形成する。具体的には、回転体10の内周面11において、供給部30がスラリーを供給しスラリーの層200を形成し、平坦部50がスラリーの層200を平坦化し、照射部70が紫外線をスラリーの層200に照射し、スラリーの層200を硬化させることで造形物の層が形成される。第1駆動部40は、回転体10の内周面11と、供給部30との相対距離を調整する。第2駆動部60は、回転体10の内周面11と、平坦部50との相対距離を調整する。スラリーは、造形物の基材である。スラリーは、例えば、紫外線硬化樹脂とセラミックス粉又は金属粉とを混合した流動性のある材料である。スラリーは、ジェル(ゲル)状、半固体状、ゼリー状、ムース状ないしペースト状(練状)の樹脂であってもよい。紫外線硬化樹脂とは、紫外線を受光することで硬化する樹脂であり、例えば、アクリル系及びエポキシ系である。
次に、第2実施形態に係る付加製造装置について説明する。本実施形態の説明では、第1実施形態との相違点を説明し、重複する説明を省略する。第2実施形態に係る付加製造装置は、第1実施形態に係る付加製造装置1と比較して、ノズルを備える点が相違し、その他は同一である。
以上、種々の例示的実施形態について説明してきたが、上述した例示的実施形態に限定されることなく、様々な省略、置換、及び変更がなされてもよい。例えば、第1実施形態及び第2実施形態におけるスラリーは光硬化樹脂を含んでもよい。この場合、照射部70は、光を照射する。
