Research on the Performance of Honeycomb Support Structure Based on SLM

Abstract

Selective laser melting (SLM) can break through the constraints of traditional manufacturing methods and enable the fabrication of lightweight and complex parts. However, in the SLM manufacturing process, the overhang structure requires a support structure to be successfully manufactured. At present, the typical support structure is the lattice structure, which has poor manufacturability, and the manufacturing defects of some of the bars cause the structure to yield in advance, and the reliability is not high. In this paper, we design honeycomb structures with different parameters. A set of structural parameters with excellent performance were obtained. The compression test was carried out using the WDW-100 universal material testing machine, which shows that the honeycomb structure of this set of parameters has high strength and meets the requirements of manufacturing. Finally, taking the sensor mount as the object, this set of parameter honeycomb structure is used for light weight reconstruction, which can obtain better weight reduction effect under the premise of satisfying the strength of the parts, which provides technical support for the lightweight design of parts.
