The complex flow channel structure inside the hydraulic manifold block and the very large pressure and impact during the work have higher requirements for its strength and molding accuracy. Selective laser melting technology is not sensitive to complex internal structure, especially suitable for processing hydraulic manifold block, such as complex internal structure of parts, as much as possible to improve the strength of the hydraulic manifold block after SLM forming is the key of the scheme. Therefore, this paper proposed a scheme of SLM forming hydraulic manifold block with rapid-solidifying, and analyzed the influence of various process parameters and coupling volume energy density on the microstructure and strength of the ultra-hard aluminum manifold block. The results show that the change of volume energy density is the key factor affecting the microstructure and mechanical properties of the superhard aluminum blocks. By changing the effect of different process parameters on the formation, microstructure, mechanical properties and crack of hIC formed by SLM, The strength of formed hydraulic manifold block was improved by heat treatment.
