Abstract

Intelligent additive manufacturing is the direction of development, and changing parameters during the manufacturing process is an effective measure to adjust the quality of the part. The purpose of this paper is to investigate the stability of single-track and multilayer fabricated Ti-6Al-4 V designed and fabricated by laser powder bed fusion with high degrees of freedom. The effects of single-track, relative density, surface quality, and microstructure and mechanical properties were investigated by designing a process strategy based on the interval powder layer thickness and regulating the process parameters. The survey shows that the point distance of less than 35 μm, the exposure time of longer than 120 μs, and the hatch spacing of greater than 70 μm can ensure the relative density of specimens with high layer thickness. The microstructure consists mainly of acicular martensite αʹ filled in columnar β grains, and acicular martensite αʹ grains are relatively sparse. The tensile strength, yield strength, and elongation of the specimens were 1109 MPa, 1053 MPa, and 5.6%, respectively. The fracture is a combination of ductile fracture and brittle fracture. The building rate was 9 mm3/s, which is higher than the results obtained in previous studies. The survey can provide theoretical support for researchers and data support for engineers.
