Heat sinks produced through this method are normally made from copper. They are produced from a solid block of metal. These heat sinks offer high design flexibility and you can achieve high fin-density. This creates more surface area and opportunity for heat dissipation. They offer medium to high performance, but their drawbacks are generally high weight and directional sensitivity.
