Path Planning Strategies to Optimize Accuracy, Quality, Build Time and Material Use in Additive Manufacturing: A Review

Round 1

Reviewer 1 Report

This review examines the progress of path planning in additive manufacturing. The rapid development and wide application of additive manufacturing calls for effective design of not only the topographical features but also the printing paths, to maximize the power of addtive manufacturing techniques. As the authors discussed, the main purposes of path planning include improving printing quality, saving materials/time, and achieving specific properties of the printed structures. The authors have done a good job organizing the detailed different strategies under these objectives. The figures are also well-made. I found this review informative and easy to comprehend. Thus I recommend it for publication. I have no specific criticisms for the current format.

Reviewer 2 Report

1. Use a more descriptive title: "Path planning strategies to optimize accuracy, quality, build-time and material use in additive manufacturing: a review."
2. The Abstract is a summary only of the Introduction; an Abstract must summarize the entire paper including results and conclusions.
3. There are numerous grammatical and style issues including the overuse of "AM." Examples of grammatical/style problems are found in lines 22, 36, 43, 47, 135, 139, 143, 154, 164, 167, 203, 209, 210, 211, 212, 216, 224, 235, 245, 246, 266, etcetera.  
4. The manuscript needs a careful review by an individual with a better command of the English language. As is, the writing is wordy and repetitive making the topics difficult to follow.  
5. Overall, this is a useful review paper on relevant subject matter, and I support its publication.
