Mmh, I wouldn't have used copper-fill on something that goes directly in contact with skin.
I had issues with light leakage with thin layers of poor-quality PETG (with light shining through as a dark-green halo), but I've printed microscope light-shields with plain black PLA and PETG with only 1.5mm thickness.
I'd surprise me if the leakage from the material would be greater than the light that comes in from the hinge itself, but I guess the author has done some tests.
- JesusFreke 6y agoI'm honestly not convinced it's actually copper filled. The listing says it is, but its density says otherwise. Regardless, it was the most opaque thing I had on hand, so.. :) There's some good info on opaque filament that people have found on this thingiverse object: https://www.thingiverse.com/thing:1662956 https://www.thingiverse.com/thing:1662956. Personally, I've also had good luck with eSun's black PLA, although it was a fairly old roll, so who knows if their formulation is still the same. And their black PETG definitely isn't very opaque.
- bsdubernerd 6y agoAs I wrote before, I frequently go mostly with some gradation of grey nowdays. I keep a selection of fingernal varnish colors for finishing touches. They dry quick, cheap, are available in any shade you need in small volumes (so you can have variety over quantity). Especially the "gel" variants often require a single coat. I wonder if this could also work for shielding, just in case you're going to repeat the print :)
