Is 365nm or 395nm better for curing resin? Choosing the right wavelength for curing resin depends on the type of resin you are using. 365nm UV light is generally more effective for curing photopolymer resins because it penetrates deeper and ensures a thorough cure. However, 395nm UV light can be suitable for certain resins and applications where surface curing is sufficient.
What Are the Differences Between 365nm and 395nm UV Light?
Understanding the differences between 365nm and 395nm UV light is crucial for selecting the right tool for your resin curing needs. Here’s a breakdown of their characteristics:
-
365nm UV Light
- Penetration: Deeper penetration, ideal for thick or dense resins.
- Efficiency: Provides a more complete cure, reducing tackiness.
- Cost: Generally more expensive due to the higher quality of light and production costs.
-
395nm UV Light
- Penetration: Shallower penetration, best for thin layers or surface curing.
- Efficiency: Suitable for applications where a quick surface cure is sufficient.
- Cost: More affordable and widely available.
How Does Wavelength Affect Resin Curing?
The wavelength of UV light affects how deeply the light can penetrate the resin and how effectively it cures. 365nm light is often preferred for its ability to cure resins more thoroughly, especially in industrial applications where quality is paramount. Meanwhile, 395nm light is popular for hobbyists and applications where cost and speed are more important than depth of cure.
Which Resin Types Are Best for 365nm and 395nm?
Different resins respond differently to UV wavelengths. Here’s a quick guide on which resins work best with each wavelength:
-
365nm UV Light
- Photopolymer Resins: Ideal for 3D printing and industrial applications.
- Thick Layer Resins: Better for resins that need a deep cure.
-
395nm UV Light
- Surface Coating Resins: Suitable for applications like varnishes or thin coatings.
- Hobbyist Resins: Great for small-scale projects where cost is a factor.
What Are Practical Applications for Each Wavelength?
The choice between 365nm and 395nm UV light often depends on your specific application needs:
-
365nm UV Light
- 3D Printing: Ensures the structural integrity of complex models.
- Industrial Coatings: Used for high-quality finishes in manufacturing.
-
395nm UV Light
- Nail Salons: Used for curing gel nails quickly.
- Hobby Projects: Ideal for DIY enthusiasts working with small-scale resin projects.

What Is the Best UV Light for 3D Printing Resin?
For 3D printing resin, 365nm UV light is typically the best choice. It ensures a complete cure, which is crucial for maintaining the structural integrity of printed objects.
Can You Use 395nm UV Light for All Resins?
While 395nm UV light can cure some resins, it may not be as effective for thicker or industrial-grade resins that require deeper penetration. Always check the resin manufacturer’s recommendations.
How Long Does It Take to Cure Resin with UV Light?
Curing time depends on the resin type and the UV light wavelength. Generally, 365nm UV light offers a faster and more thorough cure, while 395nm may require longer exposure for complete curing.
Are There Safety Concerns with UV Light?
Yes, both 365nm and 395nm UV light can be harmful to the eyes and skin. Always wear protective gear and follow safety guidelines when using UV curing lights.
What Are the Cost Differences Between 365nm and 395nm UV Lights?
365nm UV lights tend to be more expensive due to their efficiency and depth of cure. 395nm UV lights are more affordable and widely available, making them suitable for budget-conscious projects.
Conclusion
Choosing between 365nm and 395nm UV light for curing resin depends on your specific needs, including the type of resin, project scale, and budget. For industrial and 3D printing applications, 365nm is often the superior choice due to its deep penetration and thorough curing capabilities. On the other hand, 395nm offers a cost-effective solution for hobbyists and surface-level applications. Always consider the resin manufacturer’s guidelines and safety precautions when working with UV lights.
