Abstract
Description
三次元(3D)印刷において、積層印刷プロセスを用いて、デジタルモデルから三次元固体部品を作成することができる。3D印刷は、高速な製品試作、金型生成、マスター型生成、及び短時間運転の製造に使用され得る。幾つかの3D印刷技術は、材料の逐次の層の塗布を必要とすることから、積層プロセスと考えられる。これは、従来の機械加工プロセスとは異なり、最後の部分を形成するために材料の除去に依存することが多い。3D印刷において、構築材料が硬化または融合されることができ、幾つかの材料は、熱アシスト押し出し、溶融または焼結を用いて実施されることができ、他の材料はデジタル光投影技術を用いて実施され得る。
簡略化および例示のために、本開示は、その例に主に言及することにより説明される。以下の説明において、多くの特定の細部は、本開示の完全な理解を提供するために記載される。しかしながら、容易に明らかになるように、本開示はこれら特定の細部に限定されずに実施され得る。また、幾つかの方法および構造は、本開示を不必要に不明瞭にしないように、詳細に説明されない。本明細書で使用される限り、用語「a」及び「an」は、特定の要素の少なくとも1つを示すことが意図されており、用語「含む」は、以下に限定されないが含むことを意味し、用語「含んでいる」は以下に限定しないが含んでいることを意味し、用語「基づいて」は少なくとも部分的に基づくことを意味する。
