Study on SLM Forming Process, Residual Stress and Thermal Fatigue of 24CrNiMo Alloy Steel
Round 1
Reviewer 1 Report
In my opinion Fig. 7 should be described in more detail.
How was prepared the sample for TEM and what type of TEM was used?

Reviewer 2 Report
The research is very interesting but it is very poorly presented and needs extensive editing:
-clear identification of steel used (standard?)
-caption o Fig 1
-Table 2, formatting and almost all Tables
-caption of Figure 2 (identification of machine elements)
-Figure 10 and 11: one picture missing
Finally, there is not many results of thermal fatigue, therefore is the title of the paper adequate?

Reviewer 3 Report
density and residual stress stories are good
microstructure characterisation is weak, I suggest to remove TEM and spend more time on microstructure in the next paper
thermal fatigue section is also weak, so, probably, the word "fatigue" should not appear in the title
minor comments are in the file

***Global Commets
Interesting paper with appropriate methodology for research and interesting conclusions.
The introduction could be improved with a more complete literature review. Improve the reference numbers.
Conclusions can be improved.
The article needs improvement, especially in terms of formatting and editorial writing
