SLS technology does not require support structures and can easily realize complex structures that are difficult to achieve with traditional manufacturing - such as lattice structures with a hollow rate of more than 80%, multi-cavity nested parts, and complex inner cavity flow channels. For example, EPTAHUB printed an engine cooling component for an aerospace customer using SLS technology to achieve integral forming. Compared with the traditional splicing process, the part weight was reduced by 40% and the heat dissipation efficiency was increased by 25%.
