PLA UV 1.75mm filaments for 3D printing, eSun PLA-UV 1.75mm orange 1 kg

eSun PLA UV 1.75mm filament in orange is a PLA-based material formulated to respond to ultraviolet light while retaining the printability of standard PLA. Supplied on a 1 kg spool and sized for printers that accept 1.75 mm filament, this material is intended for FDM/FFF desktop printers and offers predictable extrusion, dimensional stability and a bright orange finish that can exhibit UV-reactive effects under suitable lighting.

Advantages

This filament combines the ease of printing associated with PLA — low warping, good layer adhesion and minimal odour — with UV-reactive properties that change appearance when exposed to ultraviolet light. The 1.75 mm diameter ensures compatibility with a wide range of hobby and prosumer 3D printers, and the 1 kg spool supports multiple small to medium projects without frequent spool changes. The orange color provides high visibility for prototypes and decorative pieces while maintaining consistent feeding and reliable extrusion.

Suitable for

• Prototyping of non-load-bearing parts and concept models
• Decorative objects, visual elements and color-contrast models
• Educational projects, demonstration pieces and craft applications
• Small production runs and replacement parts for consumer devices where PLA properties are acceptable

Key specifications

• Material base: PLA with UV-reactive additives
• Nominal filament diameter: 1.75 mm
• Spool weight: 1 kg
• Color: orange (UV-reactive finish)
• Compatibility: FDM/FFF desktop 3D printers that accept 1.75 mm filament
• Recommended nozzle diameter: standard 0.4 mm (subject to printer setup)

How to use

Load the spool onto the printer spool holder, ensure the filament path is free of obstructions and feed the filament into the extruder according to your printer manufacturer’s instructions. Suggested print settings typically start with a nozzle temperature in the range commonly used for PLA (consult your printer and filament manufacturer guidance), a heated bed or adhesive surface as required for first-layer adhesion, and print speeds suited to your printer’s capabilities. Allow printed parts to cool sufficiently before removal to reduce deformation. Store the remaining filament in a dry, dust-free environment to preserve UV properties and printability.

Usage recommendations

For best results, test a small calibration object to fine-tune temperature and flow settings before printing larger parts. When demonstrating UV-reactive behavior, use a dedicated UV light source to evaluate appearance changes; prolonged direct sunlight exposure may alter color over time.
