Gizmo Dorks provides the highest quality 3D printing materials such as ABS PLA HIPS PVA and more. Our filaments are run with tight tolerances. There are no air bubbles or oily residues. Every filament comes loaded on a durable hard plastic spool not a cheap flimsy cardboard spool. The blacklight filament will shine under the presence of black light which is also known as UV-A or ultraviolet light. Create a wonderful wide variety of prints that will glow under black light and stand out in the darkness.
