I am trying to use UV-VIS for a 3D printed ~4mm PLA design. However I keep running into a problem because the polymer is not showing detectable under the UV-VIS. Does anyone have any suggestions that would allow for visibility of PLA? Any recommended papers would be of great use as well.

I also thought of possibly placing spider silk inside but this would implement an array of complexity in the product.

Thanks guys

  • $\begingroup$ Based on your question, I think you're trying to estimate the UV/Vis absorption of the PLA sample? What wavelength range are you examining? $\endgroup$ – Geoff Hutchison Jan 28 '18 at 1:12
  • $\begingroup$ The wavelength was between 200 and 800. We could not see any data form between 400 and 800 nm $\endgroup$ – Josh G Jan 29 '18 at 3:28
