ORTUR Laser Module Guide: How to Pick the Perfect One for Your Ortur Laser Engraver

In laser engraving, the laser module is the "core engine" — it directly determines engraving precision, applicable materials, and processing efficiency. As a beginner-friendly brand, ORTUR offers laser modules covering a full power range from 1.3W to 40W, plus dedicated infrared laser models (LR4-1A 1.3W IR and LR4-2B 2W IR) for metal engraving. This guide will help you pinpoint the laser module that "solves your specific needs".

Smaller spot = finer engraving

The LU2-2 (0.07×0.06mm spot) is great for fine illustrations or coated metal jewelry marking; the 10W LU2-10A (0.05*0.1mm spot) excels at large-area engraving, balancing speed and efficiency.

Focal length affects processing adaptability

Short focal lengths (e.g., 30mm for LU2-4 SF) are for flat, fine engraving while long focal lengths (e.g., 50mm for LU2-4 LF) have a longer depth of field, suitable for cutting.

Lifespan & Maintenance

Reduce Long-Term Costs

  • All ORTUR modules have a lifespan of over 8,000 hours.
  • Clean the lens surface with alcohol-dampened cotton balls every 30 hours to remove dust and dirt, then wait for the alcohol to evaporate. For detailed lens maintenance,please refer to: https://www.youtube.com/watch?v=KNRM_VdWECk
  • Using an air pump is recommended for better cutting results and extended module lifespan.

Pitfall Warnings: 3 Common Mistakes Beginners Make

  • Confusing "Optical Power" with "Electrical Power" : "Adapter Power Input" in the module specs (e.g., 24V/4A for LU2-10A) only refers to power supply requirements, and the actual processing capability depends on "Optical Power".
  • Ignoring Machine-Module Compatibility: All laser modules for Ortur H20 are custom-made — they only work with the Ortur H20 and cannot be adapted to other Ortur laser engravers.
  • Choosing the Wrong Module for Pure Metal Engraving: For pure metal engraving, a 1064nm infrared laser module is a must and the blue laser modules only work with coated metals and other non-pure metals.

In short, the core logic for choosing an ORTUR laser module is "needs first" — clarify your "processing materials (non-metal/pure metal), machine compatibility, and expansion needs", then select based on power, spot size, and accessory compatibility. ORTUR’s full-range laser module lineup, from entry-level 5.5W to mass-production 40W, and from blue laser to infrared metal-specific models, covers all needs from beginners to professionals. Follow this guide to avoid mistakes and find your perfect "core engine".
