Reviewer 1 Report
The authors study the photosensitivity of a 3D printed silica fiber with a 1030nm 240fs laser. They can show that 3D printed fibers demonstrate similar (or better) thermal stability than commercial single-mode fibers. I am impressed about this paper because it shows that with a relatively simple 3D print they can open a new field for design high-temperature components suitable for a huge variety optical elements. I can technically understand that the section of the fabrication of the resin used for 3D print is relatively short. It would be a help for other groups who want to verify the findings of the authors to be more precise in this section. In any case I highly recommend this paper for publication.

Reviewer 2 Report
The manuscript is well written and the results and discussion are clearly shown. I have a few comments/questions to include in the discussion:
- Can you improve the contrast in the inset of Figure 1? The core is hardly visible.
- Please, explain how the SEM images in Figure 3 have been performed, i.e, is the sample cut/prepared somehow? Has been applied some etching process to make the nanogratings visible?
- Have you performed EDX measurements after the laser irradiation? Is there any change in the composition of the irradiated region?
- Have you performed SEM measurements of the nanogratings after the annealing? Is there any change in the microstructure after the annealing process?
