Undercut and overhang angle control in topology optimization: A density gradient based integral approach

Summary We present an approach for controlling the undercut and the minimal overhang angle in density based topology optimization, which are useful for reducing support structures in additive manufacturing. We cast both the undercut control and the minimal overhang angle control that are inherently...
