3D Printing: Best FDM Filaments & Techniques
3D printing with neon-colored filaments allows makers to create bold, high-visibility, and unique prints that stand out. Whether for decorative, functional, or industrial applications, neon materials add an aesthetic and practical advantage by improving visibility, making objects easier to spot in low-light environments.
At MakerVerse, we understand the importance of material selection for high-quality prints. Neon filaments offer both style and functionality, making them an excellent choice for various applications.
Types of Neon Filaments for FDM Printing
Several FDM-compatible filaments are available in neon colors. The most common options include:
- PLA Neon – Easy to print, great for aesthetic and decorative prints.
- ABS Neon – More durable, suitable for functional parts, but requires a heated bed.
- PETG Neon – Good balance between durability and ease of printing, ideal for outdoor and mechanical applications.
- TPU Neon – Flexible neon filaments for soft or impact-resistant prints.
For a detailed comparison of these materials, check out our guide to FDM 3D printing materials.
Key Benefits of Neon Filaments
- High Visibility – Perfect for safety gear, signage, and warning indicators.
- Aesthetic Appeal – Adds a striking, futuristic look to artistic and decorative projects.
- UV Reactive – Some neon filaments glow under UV light, making them ideal for unique displays and entertainment purposes.
- Customization – Available in a variety of shades, allowing for personalization and branding.

Challenges and Considerations
While neon filaments offer many benefits, there are some challenges to consider:- Opacity Issues – Some neon colors may be slightly translucent, affecting the final appearance.
- Higher Cost – Neon filaments can be slightly more expensive than standard colors.
- Printing Adjustments – Some require fine-tuning print settings for optimal color vibrancy and layer adhesion.
Technical Considerations for Printing with Neon Filaments
To achieve high-quality results, follow these best practices:- Extrusion Temperature:
- PLA: 190-220°C
- ABS: 230-250°C
- PETG: 220-250°C
- TPU: 210-240°C
- Bed Temperature:
- PLA: 50-60°C
- ABS: 90-110°C
- PETG: 70-90°C
- TPU: 50-60°C
- Use an Enclosure for ABS: Helps prevent warping due to temperature fluctuations.
- Optimize Layer Height: Lower layers (0.1mm-0.2mm) enhance surface smoothness and color consistency.
- Use Proper Lighting: Neon prints look best under bright or UV lighting for maximum effect.
- Store Properly: Keep filaments in a dry, airtight container to prevent moisture absorption, which can affect print quality.
Applications of Neon 3D Prints
Neon-colored 3D prints are used in various industries and creative fields, such as:- Prototyping – Creating highly visible, easily identifiable prototype parts.
- Sports Equipment – High-visibility gear like bicycle accessories, running markers, and custom protective gear.
- Signage & Labels – Eye-catching labels, logos, and warning signs.
- Cosplay & Fashion – UV-reactive props, accessories, and wearable pieces.
