Reviewer 2 Report
This manuscript is to determine the silk powder of suitability for use in 3D printing. Two different silk powders are compared with hydroxyapatite powder using in 3D printing. The powder size, shape, bulk behaviour, dynamic flow behaviour, and shear behaviour were examined. This work sounds interesting. Here are some comments
- In the comparison surface analysis of particle shape data, the mechanism and impact factors should be described;
- What about the shortcomings of the three particles using 3D printing, and how to solve them in the 3D printer used? The focus should be more about the impact of the properties of particles on 3D printing, such as dispersion, flowability, etc.
- More evaluation about the initial printed construct should be carried out to verified the efficiency of the 3D printer and the printing feasibility of silk powder.

Reviewer 3 Report
The paper “Understanding Morphology, Bulk Properties and Binding of Silk
Particles for 3D Printing” by Daniel Whyte et al. is clear and well written.
I list in the following very few points that the Authors should consider before publication.
The description of the figures appears somewhat redundant: it is written both in the title (inside the Figure) and the caption.
Some text editing should be addressed:
- throughout the text (Figures and Tables included) “ml” should be written “mL”.
- Line 464: 99% should be 99 wt.%.
- Pages 2,3,4,5,7: some typing errors are present.
Moreover, in my opinion, the reference list should be implemented.

Round 2
Reviewer 1 Report
Thank you for the revision, I only have one request from the authors.
Please add the cross-section and surface image of the SEM of the initially printed construct developed solely from silk powder. (Figure 14-Left)
