High Power Blue 425nm 5W Fiber-Coupled Laser Module for 3D Printing & Photopolymerization

This High Power 425nm 5W Fiber-Coupled Laser Module is a cutting-edge light source specifically engineered for 3D printing and photopolymerization applications. The 425nm wavelength sits at the sweet spot of photopolymer absorption, while the 5W high power enables deep curing and fast processing. The fiber-coupled design provides flexible integration with various 3D printing systems, making it ideal for industrial-grade SLA/DLP printing, rapid prototyping, and mass production.

Core Technical Advantages

1. 425nm Wavelength Optimization for Photopolymerization:

• Perfect Match for Photopolymer Absorption: The 425nm wavelength aligns precisely with the absorption peaks of most commercial photopolymers (especially acrylic-based resins), enabling 30-50% higher energy transfer efficiency compared to 405nm alternatives.

• Optimal Penetration Depth: Provides 0.5-2mm tissue penetration in resins—deep enough for full curing of standard layers yet shallow enough for precise detail reproduction.

• Reduced Yellowing Risk: Compared to shorter UV wavelengths, 425nm minimizes post-curing yellowing in transparent resins, maintaining product clarity.

2. 5W High Power for Industrial-Grade Performance:

• Industry-Leading Curing Speed: Delivers 5-8x faster curing rates than standard 100-500mW systems, reducing build times by up to 70%.

• Full Depth Curing: 5W power ensures complete polymerization through thick resin layers (up to 2mm) in a single pass, eliminating secondary curing needs.

3. Fiber-Coupled Design for Flexible Integration:

• Precision Delivery: Equipped silica fiber (1000μm core, 0.22NA) channels 95%+ of laser energy with minimal loss.

• System Compatibility: Detachable SMA905/FC connector enables easy integration with any 3D printing platform (SLA, DLP, LCD).

• Mechanical Freedom: 1-3m fiber length allows positioning the laser module away from heat-sensitive components while maintaining beam quality.

Applications Beyond 3D Printing

• Photopolymer Molding: Rapid tooling for small-batch production.

• Dental Applications: Crown/bridge fabrication, orthodontic appliance production.

• PCB Manufacturing: Direct imaging for circuit boards with higher resolution than traditional UV.

• Microfabrication: Production of microfluidic devices, sensors, and optical components.

Summary

The 425nm 5W Fiber-Coupled Laser Module represents a leap forward in 3D printing technology, offering unmatched curing speed, precision, and material versatility. By combining the optimal 425nm wavelength with industrial-grade 5W power and flexible fiber delivery, it empowers manufacturers to produce higher-quality parts faster while reducing operational costs. Ideal for both prototyping and high-volume production, this module is poised to become the standard light source for next-generation photopolymer 3D printing.
