3D printing filament products and luminous material guides

Various 3D printing filaments are currently available through various retail promotions. 3DHoJor is offering a 1kg spool of 1.75mm glow-in-the-dark PLA filament in green at a discounted price via Amazon. Additionally, ELEGOO is providing a bulk deal on eBay for 1kg spools of 1.75mm filament, offering five spools for $40.76 through a buy-three-get-two-free promotion.

Luminous filaments, such as eSUN PLA-Luminous, are noted for their ability to absorb energy from light sources—with UV light providing a stronger charge than sunlight—and release it as a glow in darkness. This material is frequently used for seasonal decorations, such as Halloween props, to create atmospheric lighting effects.
