Review on 🖨️ ECHEN 1.75mm Printer Filament Spool: Superior Printing Technology by Rob Rogers

All three filaments produce a very pleasant glow effect when the light is switched off. The second photo shows them after charging, but with the lights on. The third photo shows direct sunlight. As you can see, when the light is on, this material appears off-white and somewhat translucent. Every light source I've tried so far has successfully charged the Glow effect, including LEDs, fluorescent, CFL, incandescent, and especially sunlight and UV light. Brighter light or more UV light charges the material better for a brighter shine. An LED or black light fluorescent lamp is a great way to quickly and fully charge it; and sunlight really works best! Prints easily with my typical PLA settings with no adjustments. Thin walls, bridges and ledges were no problem. N:218 -> 206CB: 60 -> 55CFan: HIGHSpeed: Normal
