Abstract
The tungsten thin wall parts which were used as high-performance collimator devices were fabricated by optimizing selective laser melting laser parameters. The effect of laser power and scan rate on wall thickness and surface morphology of tungsten thin wall parts was investigated, respectively. The results indicated that the wall thickness increased with the enhancement in laser power as a linear relationship. On the contrary, the wall thickness decayed exponentially with the acceleration in laser scan rate. Meanwhile, the wall thickness of the parts fabricated by laser double-pass melting was thinner than that fabricated by laser single-pass melting. In addition, mathematic models for selecting suitable laser power and laser scan rate to fabricate specified tungsten thin wall parts were proposed. Furthermore, the effects of laser parameters on the top surface roughness, adhesive parts and hot cracks were also discussed.
