ワイヤ+アーク方式金属3Dプリンタを用いた大型アルミ部材の造形

抄録

Over the past few years, the concern over manufacturing of building materials using a WAAM-based metal 3D printer has risen. Although studies have been conducted mainly with steel-based materials, there are relatively few examples of using aluminum, which is frequently used as exterior materials.

In order to investigate the feasibility of using the metal 3D printer for large aluminum components, a chair was designed and manufactured. In the design, the chair with a hollow cross-section of 420 mm (width) x 400 mm (depth) x 600 mm (height) was designed. In manufacturing, it was confirmed that the designed chair could be fabricated, indicating that a relatively large hollow structure made of aluminum can be fabricated with the WAAM-based metal 3D printer.
