Clearest 3D print Filament

[jjput1]

Hello all,

I am trying to make a print that needs to have a filament which is see through. I was wondering if anyone had recommendations for the most see through filament.
I am currently looking at t-glase, hd-glass by form futura, and makergeek's PETG filament so if you have used these and one of them was most clear please let me know.

Thanks

Post treatment of PET (or tglase) actually brings a lot. You can find an article here or on taulman's about the improvements brought by XTC 3D epoxy to single shell transparent prints. It won't be good enough for optics but it is good enough for decoration stuff.
Also the general advice is to print hot.
