c-tech PLA 1.75 mm luminous filament — RAL 2007 bright orange, 1 kg (3DF-P-PLA1.75-2007)

c-tech PLA 1.75 mm luminous filament in bright orange (RAL 2007) is a 1 kg spool of PLA designed for FDM/FFF 3D printers that accept 1.75 mm filament. The material combines standard PLA printability with a luminescent pigment that produces a vivid orange finish that can glow in low light after exposure to a light source. The filament is suitable for prototyping, decorative elements, markers and hobby prints where visibility and color intensity are important. It is intended for use with common PLA temperatures and benefits from dry storage to maintain consistent extrusion and adhesion.

Advantages

This luminous PLA offers easy printing characteristics typical of PLA, including low warping and good layer adhesion, while delivering enhanced visibility through its bright orange color and glow-in-the-dark effect. The 1.75 mm diameter provides compatibility with most consumer and prosumer FDM/FFF printers, and the 1 kg spool supports multiple small to medium prints. The pigment is integrated into the filament for uniform color and luminescence across prints when exposed to charging light.

Suitable for

• Prototyping brightly colored parts and concept models
• Decorative objects, signage and markers that require glow-in-the-dark visibility
• Hobby prints, cosplay accessories and model details
• Safety markers and small components needing high color contrast

Key specifications

• Material: PLA (polylactic acid) with luminescent pigment
• Diameter: 1.75 mm nominal
• Spool weight: 1 kg
• Color: bright orange (RAL 2007) with glow-in-the-dark properties
• Compatibility: FDM/FFF printers that accept 1.75 mm PLA filament

How to use

Load the filament into the extruder of a compatible 1.75 mm FDM/FFF printer and set printing temperatures suitable for PLA. Typical nozzle temperatures range according to your printer and PLA grade; begin with commonly used PLA settings and adjust based on layer adhesion and surface finish. Use a heated bed if available for improved first-layer adhesion, or a suitable adhesive on the build surface. After printing, allow parts to cool gradually on the build plate to reduce deformation. To maximize luminescence, expose printed parts to a strong light source before use.

Usage recommendations

Store the filament in a dry environment, ideally in sealed packaging with desiccant, to prevent moisture uptake that can cause bubbling or degraded print quality. Avoid prolonged high-temperature storage and keep the spool away from direct sunlight when not in use.
