Abstract
Since the traditional metal filter cannot filter layer-by-layer and easily block defect caused by the right-angle relationship between the pore structure and the filtration object, the design method and the forming process of the selective laser melting (SLM) forming filter need to be studied. This paper presents a truss structure filter designed by a parameterization modeling approach. The finite element method is applied to conduct model flow simulation analyses for the parameterized filter’s porous structure. The SLM forming process is also optimized by adjusting the placement and support structure of the filter. The truss structure filter established via the proposed approach demonstrates favorable modeling effect and even grid distribution; the fluid has relatively high flow speed and low pressure when passing through the truss structure filter. The connection among the SLM porous partial supports and the connectivity among the pores are close, there is little powder attachment on the surface after processing, and the filter can be directly utilized after simple polishing.
