We already spilled the beans (dots?) in January's CES showcase + press release, but below is what we've learned since then. We recommend to start by reading our press release.
Red, orange, yellow, and green! Isn't it shocking? Doesn't look like much in natural light, but once excited by 365 nm black light the fluorescence is exceptional! That's it. It's all about the incomparable brightness under blacklight in our easy-to-print, high performance Protopasta HTPLA. I can't with to see what you print!
One benefit of being so translucent is you can print a thin layer on top of a more saturated color. In that case, the print will look like the saturated base color, but fluoresce red, orange, yellow, or green!!! Amazing, right? See how Corey (CM Design) and Daniel (Kaizen3D) each apply this technique. Example photo excerpt from a video by Corey below:
I can't wait to see your creativity with Quantum Dots!!! Tag Protopasta with your makes :-)
Missed out on March's Endless Exploration? We hope to release Quantum Dot Filaments in in April, and don't forget to subscribe by April 30th for our next Endless Exploration (contents TBD).
Take care and enjoy the pasta,
Alex and the Protopasta Team
3D Printing with Protopasta HTPLA
Like most other Protopasta PLA and HTPLA, we 3D printed at 240C nozzle and 55C plate at maximum volume rate of 12 mm3/s using the generic PLA profile on the Bambu P1S with a 0.4 steel nozzle. Find more material data listed here.

About QD chemistry and safety
Quantum dots (QDs) are made of multiple layers that include indium phosphide at it's core, encapsulated by other materials typically found in digital displays.
From Google's AI overview: Indium phosphide (CAS 22398-80-7) is listed under California's Proposition 65 as a chemical known to cause cancer, effective February 27, 2001. Because there is no safe harbor limit, we must disclose this ingredient. That said, the loading level is <0.1%, it is encapsulated, and ingesting or inhaling is virtually impossible. Do not sand or generate dust. If you do, use proper PPE. Even if ingested or inhaled, you'd choke or suffocate before intaking a toxic level of indium phosphide.
Unrelated but worth noting: Fluorescence can degrade with exposure to UV light, so if you wish to retain that property, do not leave by a window or in light in general when not in use. To best preserve the filament and print properties, store in a cool, dark, and dry place.
