The surface structure of the 3D printed Ti alloys samples can be regulated by the diameter of the metal microspheres, the power of the 3D laser beam, the scanning rate and other process parameters. But when I made change in these parameters I found there are only slight difference in the microstructure of 3D printed samples in scanning electron microscopy (SEM) images. Here I would like to ask:
Try to make the diameter smaller.
Accelerate the scan rate.
Increase friction (surface characteristics of materials).
@ Gabi Nehme
Thank you for your suggestions. Please could you clarify more? What do you mean by make the diameter smaller? You mean the diameter of Ti powder particles? and "friction"?
In terms of scan rate, I already made a change in the scan rate whereas the scan rate has been increased and decreased 30% and 60%, but still very slight change in the structured surface.
Thanks again
