Sample name: turbine cooling test bench

Printing device: FS421M

Printing material: FS Ti6Al4V


The turbine cooling test-bed is used for dynamic test of different turbine blades. The flaky structure of the outer wall improves the rigidity of the part without increasing the thermal mass. Huashu FS421M equipment is used for integrated molding, with size of 365 × three hundred and sixty-five × 320mm, wall thickness 0.8mm, weight 6.46kg, printing time 144 hours. The surface roughness Ra in the vertical direction is 3 um, and the surface roughness Ra in the 45 ° direction is<10 um.
