The hardness and specific wear rate of 3 dimensionally (3D) printed Ti6Al4V specimens were studied with respect to heat treatment temperature (HTT) in a range of 400-800 °C. Increasing the HTT from 400 °C to 500 °C promoted the hardness of the printed specimen while its decreased hardness associated with a further increase in the HTT to 800 °C was observed. Since higher wear resistance was the result of higher hardness, the trend of specific wear rate versus HTT of the printed specimen was opposite to that of its hardness versus HTT. The highest hardness and lowest wear of the printed specimen were therefore found at the HTT of 500 °C.

Achieving 3D printed Ti6Al4V alloy with customized microstructures and mechanical characteristics remains challenging, wherein the processing e ciency mainly depends on the laser energy, mass deposition rate, and duration. Based on these factors, a simple and eco-friendly direct laser metal deposition approach was followed to get 3D printed Ti6Al4V alloys at various laser powers (300-500 W).Herein, a 1.5 kW continuous ber laser of wavelength 1080 nm was used to create the stable and dense alloy. The obtained 3D printed specimens were characterized to assess the laser power-dependent microstructures, compositions, microhardness, grain sizes, color-lling and dimensional stability in terms of height/width. FESEM micrographs of the obtained alloys revealed the existence of porous spherical grains of mean size in the range of 50-81 𝜇𝑚. The alloy deposited at 300 W and 0.495 mm/s scan speed displayed the maximum hardness (excellent bong strength) value of 859.2 HV 0.5 devoid of any crack and porosity. XRD patterns of the alloy revealed the existence of α + β martensitic phase transformation which as responsible for the marginal increase of hardness. It is asserted that the proposed 3D printed Ti6Al4V alloy can be bene cial for the development of e cient structural parts desired for diverse applications.
