Why Choose the AlgoLaser 1064nm Module Over a 20W Fiber Laser?

The AlgoLaser 3W 1064nm laser engraver module offers several advantages over a traditional 20W fiber laser engraving module when it comes to engraving tasks, particularly for delicate materials like copper plates. Here are the key advantages that make the 3W module a superior choice:  


1. Shorter Pulse Width for Higher Precision

  • AlgoLaser 3W Module (3ns Pulse Width): The 3W module's pulse width is only 3 nanoseconds, which is significantly shorter than the 100 nanoseconds pulse width of the 20W fiber laser. This shorter pulse duration allows the 3W module to deliver energy more precisely and with less heat impact on the material. It reduces heat-affected zones and minimizes material deformation, resulting in smoother and cleaner engravings, especially on intricate patterns or fine features.
  • 20W Fiber Module (100ns Pulse Width): The longer pulse duration can lead to increased thermal effects, causing rougher edges or deeper heat penetration. This may not be ideal for materials like copper that are sensitive to heat.


    • 2. Higher Peak Power for More Efficient Engraving

  • AlgoLaser 3W Module (50,000W Peak Power): The 3W 1064nm module reaches a peak power of 50,000 watts, which is five times higher than the 10,000 watts peak power of the 20W fiber module. This higher peak power allows for more efficient material removal in a shorter burst, leading to quicker engraving speeds and the ability to achieve finer details. The high peak power is particularly beneficial for engraving tasks that require precision without causing excessive heating.
  • 20W Fiber Module (10,000W Peak Power): While still effective for deep engraving tasks, the lower peak power may struggle to achieve the same level of fine detail and control as the 3W module.


    • 3. Lower Single Pulse Energy for Delicate Control

  • AlgoLaser 3W Module (0.15mJ Single Pulse Energy): The 3W module has a lower single pulse energy of 0.15 millijoules, making it advantageous for tasks that require detailed engraving. The lower energy helps reduce heat accumulation on the material, minimizing the risk of material damage or discoloration and allowing for greater precision.
  • 20W Fiber Module (1mJ Single Pulse Energy): Higher pulse energy can be useful for deeper material penetration, but it may not offer the same level of control over delicate details, potentially causing more thermal impact.


    • 4. Optimized Frequency for Engraving Quality

  • AlgoLaser 3W Module (20KHz Frequency): The 3W module operates at a frequency of 20KHz, which provides a balance between speed and engraving accuracy. This frequency range is ideal for high-quality surface engraving on materials like copper, where control over fine details is critical.
  • 20W Fiber Module (25-28KHz Frequency): Although the 20W module's frequency range may be suitable for deeper engraving applications, it may not deliver the same high-precision surface detailing as the 3W module.


    • 5. Reduced Thermal Effects: Ideal for Sensitive Materials Like Copper

  • AlgoLaser 3W Module: The combination of shorter pulse width and higher peak power ensures that the 3W module minimizes heat impact on the engraved surface. This makes it well-suited for materials that are sensitive to heat, such as copper. Reduced thermal effects lead to a smoother surface finish and better preservation of fine details.
  • 20W Fiber Module: With a longer pulse duration, the 20W fiber module may cause more pronounced thermal effects, making it less ideal for heat-sensitive materials that can warp or discolor under high temperatures.


    • 6. Cleaner Engraving Results with Minimal Post-Processing

  • AlgoLaser 3W Module: Due to its precise energy delivery and reduced heat impact, the 3W module often requires less post-processing work, such as polishing or cleaning up rough edges. This can save time and effort in projects where a smooth and polished finish is important.
  • 20W Fiber Module: Deeper engravings with a 20W module may necessitate more post-processing to remove rough edges or surface discoloration caused by higher thermal impact.


    • 7. Better Control Over Fine Details

  • AlgoLaser 3W Module: The 3W module's characteristics allow it to create intricate patterns and detailed engravings with high accuracy. This makes it especially suitable for fine artwork, jewelry design, or engraving small text on metal surfaces.
  • 20W Fiber Module: While the 20W module is effective for larger and deeper engravings, it may not achieve the same level of detail and crispness when working with fine lines or small features.


    • 8. Enhanced Engraving Speed and Efficiency

  • AlgoLaser 3W Module: The higher peak power and shorter pulse duration of the 3W module enable quicker material removal in short bursts, speeding up the engraving process without compromising quality. This efficiency can be a significant advantage in industrial settings or for high-volume engraving tasks.
  • 20W Fiber Module: The engraving process may be slower with the 20W module, particularly when trying to achieve fine details, as it may require multiple passes or slower speeds to avoid excessive thermal impact.


    • 9. Greater Flexibility in Application

  • AlgoLaser 3W Module: Its ability to produce high-quality, detailed engravings makes the 3W module versatile across various applications, from artistic projects to industrial marking. It can be used effectively on a range of heat-sensitive materials, including copper, brass, and certain alloys.
  • 20W Fiber Module: More suitable for applications that require deeper engraving or marking on harder materials, but with less versatility in achieving detailed surface work on heat-sensitive substrates.


    • 10. Energy Efficiency and Cost-Effectiveness

  • AlgoLaser 3W Module: The lower overall power consumption of the 3W module can lead to energy savings, making it a cost-effective choice for frequent use in precision tasks.
  • 20W Fiber Module: Although it provides more raw power, the increased energy usage may not be necessary for tasks that require fine detail, potentially leading to higher operating costs.


    • Conclusion

    The AlgoLaser 3W 1064nm laser engraver module outperforms the traditional 20W fiber laser engraving module in several key areas, especially when it comes to engraving delicate materials like copper. Its advantages include a shorter pulse width for higher precision, higher peak power for efficient material removal, reduced thermal effects, and better control over fine details. While the 20W fiber module may still be effective for deeper engravings or tougher materials, the 3W module is the superior choice for applications where detail, surface quality, and minimal heat impact are essential.
