摘　　要：TiC steel-bound cemented carbide body was prepared by direct writing printing.The effects of powder content(89.28,89.49,89.69,89.88,and 90.07 wt%)and dispersant content(0.017,0.034,0.051,and 0.068 wt%)on the slurry and printing body were studied.The experimental results show that with the increase of powder content,the viscosity of the slurry gradually increases,the settlement rate gradually decreases,and the size and linewidth of the blank body gradually decreases.When the powder content is 89.69 wt%,the sedimentation stability and extrusion stability of the slurry are the best,and the density of the blank body is the highest,which is 3.8275 g/cm^(3),which is suitable for direct writing printing.The addition of dispersant reduced the viscosity of the slurry;With the increase of dispersant content,the surface line width and size of the printed body gradually increased.When the dispersant content is 0.034 wt%,the extrusion stability of the slurry is the best,and the density of the body is the highest,which is 3.8901 g/cm^(3).
