The design and additive manufacturing of an eco-friendly mold utilized for high productivity based on conformal cooling optimization

Materials & Design, 2022
This study proposes an eco-friendly (ECO) mold that is fabricated using the laser powder bed fusion (LPBF) method, which utilizes a three-dimensional (3D) cooling channel. Unlike previous studies, we designed surface-type conformal cooling channels (CCC)
