Parametric Optimization of Selective Laser Melted 13Ni400 Maraging Steel by Taguchi Method

Round 1

Reviewer 1 Report

In this manuscript, the authors studied the SLM additive manufacturing of a novel 13Ni400 maraging steel. The SLM parameters were optimized by Taguchi method. A combined high strength and ductility were achieved. The results are interested. And the manuscript was well written. I recommend to accepting it for publication.  

This manuscript can be accepted for publication as it is.

Reviewer 2 Report

The manuscript entitled Parametric optimization of selective laser melted 13Ni400 maraging steel by Taguchi method describes the results of experimental research in the field of the additive manufacturing of 13Ni400 maraging steel using the Selective Laser Melting process. As part of the experimental research, the authors used samples of the newly developed gas atomized powder. They optimized the process parameters using the Taguchi approach. They analyzed the effect of laser power, scan speed, layer thickness, and hatch distance on relative density, surface roughness, microhardness, and tensile strength. This is a highly topical issue that is useful in selecting optimal process conditions to create defect-free SLM parts with maximum density. The manuscript is written to a high standard and I find the information it provides very valuable.

Although the submitted manuscript is well written, it is necessary to complete some parts and answer the following questions:

1. At the end of the manuscript, it is necessary to add a discussion in which the author evaluates the results achieved in the context of the knowledge known so far in the researched area. It should be emphasized that important qualitative or quantitative points of agreement or disagreement between the results in this paper and the cited references in the manuscript must be stated at the conclusion of the manuscript.

2. It is necessary to improve the readability of figures 2, 4, 7 and 11.

3. The conditions of the performed optimization are not entirely clear. It is necessary to explain in more detail how the authors reached the optimization conclusions.

4. The direction of further experimental research in the given area should be added to the manuscript at the end.

The manuscript is processed at a very high level and after minor adjustments and additions it can be published in the Journal of Manufacturing and Materials Processing.

(1) At the end of the manuscript, it is necessary to add a discussion in which the author evaluates the results achieved in the context of the knowledge known so far in the researched area. It should be emphasized that important qualitative or quantitative points of agreement or disagreement between the results in this paper and the cited references in the manuscript must be stated at the conclusion of the manuscript.

Thanks for the comments. As suggested, a discussion has been included in the revised version of the manuscript.

(2) It is necessary to improve the readability of figures 2, 4, 7 and 11.

The readability of the figures 2, 4, 7, and 11 are improved as suggested.

(3) The conditions of the performed optimization are not entirely clear. It is necessary to explain in more detail how the authors reached the optimization conclusions.

We oblige with the reviewer’s comments and accordingly, we have included more explanation about the optimization process in the manuscript. The revised version now provides a detailed account of how the authors reached the optimization conclusions, enhancing transparency and clarity in the optimization and validation section.

(4) The direction of further experimental research in the given area should be added to the manuscript at the end.

As recommended an outlook of research has been included.
