Review on 🖨️ ECHEN Printer Filament 1.75mm: A High-Quality Filament for 3D Printing by Noe Miceli

Beautiful bright blue! In the dark it glows with a very pure blue light, there is no green in it at all. 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! This bright blue PLA prints easily at my typical PLA settings with no adjustments. Thin walls, bridges and ledges were no problem. N:218 -> 206CB: 60 -> 55CFan: HIGHSpeed: Normal
