Capillary-Driven Microdevice Mixer Using Additive Manufacturing (SLA Technology)

Round 1

Reviewer 1 Report

Comments and Suggestions for Authors

The current manuscript characterizes the performance of additively manufactured capillary-driven microdevice mixer fabricated by SLA technique. The manuscript is well-written and the materials and methods are clearly presented. However, there are some issues to be considered as follows:

- The "SLA" abbreviation should be included in the title as a complete expression.

- It is recommended to define the abbreviation through the text instead of displaying the abbreviations list by the end of the manuscript. 

 how many samples were fabricated and tested? what about the standard deviation in the measurements in case of testing more than one sample? 

 The conclusion should include the main results, contribution, and novelty of the current study using a bullet points style.

Reviewer 2 Report

Comments and Suggestions for Authors

This study proposes a passive device suitable for mobile chip laboratories to eliminate the need for external power supply. Using SLA technology to prepare complex geometric shapes to explore common laminar flow behavior in micro devices. After review, the following problems exist:

1.     The VIDEO AND IMAGE PROCESS section, the specific parameters and equipment models for image acquisition need to be further explained. Image processing methods require further accurate and detailed descriptions, including steps, etc. You can refer to the following articles:Journal of Materials Science & Technology. 2024. 177: 44-58; IEEE Signal Processing Magazine, 2023, 40(4): 61-71.

 2.     How is the fluid velocity obtained in this article? How to determine its readiness?

 3.     The comparison of the simulation results with the experimental results in Fig. 14. needs to be further elaborated in the manuscript.

 4 Two sections 3.3.4 appear in the manuscript.

Reviewer 3 Report

Comments and Suggestions for Authors

The manuscript deals with the stereolithography (SLA) of a novel microfluidic mixer designed to blending two fluids with high efficiency. Authors have systematically studied the roles of the structure of Micro-mixers in performance, and simulated the mixing process. Authors have concluded that the process time is remarkably swift at 3 seconds, with a working flow rates range from 1 µL/s to 37 µL/s. However it would be great if the presentation of the  Figures in experimental section  can be refined.

Overall the study is rigorous and manuscript is well written. It can be published with minor revision.
