?Glow in the Dark Green?Luminous PLA is processed by a special technique, it can glow in the dark after absorbing light energy. Glowing effect is stronger when exposed to UV light. Please note that this type of filaments should avoid long-time direct sunlight exposure. ?Dimensional Tolerance +/- 0.03mm?Minimum tolerance and low warping to ensure consistent feeding and stable prints, no clogging, extremely high successful rate, resulting in printed parts that have an outstanding surface finish and are highly precise. ?Tangle Free & No Plugging?Total Length: 340-350m. Full 1KG 3D printer filament reel, perfect roundness and very tight diameter tolerance, does not overlap or tangle. Melt well, feed smoothly and constantly without clogging the nozzle or extruder. ?High Compatibility?Compatible with most of FDM 3D Printers that use 1.75MM filament, Such as: Prusa, Reprap, Afinia, MakerBot, PrintrBot, UltiMaker, Airwolf, Aleph Objects, Makergear, Up, Lulzbot, Simplify3D, Flashforge, etc. ?Vacuumed Sealed Packaging?Net Weight: 1KG. eSUN filament comes in a sealed vacuum bag with a desiccant bag to keep it dry and keep out dust and foreign particles, prevent nozzle jams and yield smooth 3D models.
