Traditional sand casting follows a linear "design → pattern-making → molding → pouring" process, while 3D printed sand casting streamlines production by digitally integrating these steps, reducing lead times by over 60%. This guide breaks down how this technology transforms digital models into precision metal parts.
Case Study: A hydraulic valve body achieved 23% weight reduction through topology optimization while incorporating internal spiral channels impossible with traditional methods.
