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".

Higher Isn’t Always Better — Match Your Needs
5.5W LU2-4 SF/LF
First choice for beginners. The SF model is ideal for engraving wooden pendants or greeting cards while the LF model can cut 10mm pine boards. It offers great value for money, perfect for home users on a budget.
10W LU2-10A
Core choice for advanced users. It can cut 5mm acrylic or 8mm pine in one pass while handling fine engraving, making it a top pick for craft enthusiasts.
20W LU3-20A
Professional-grade option. It cuts 10mm plywood, 8mm black acrylic, and 15mm pine, and supports color engraving on stainless steel — suitable for small-scale side businesses.
40W LU3-40A
Industrial-grade efficiency. With switchable 40W/20W power, it cuts 15mm plywood, 15mm black acrylic, 20mm pine, and 0.3mm stainless steel, designed for mass production.
1.3W IR LR4-1A & 2W IR LR4-2B
Specialized for pure metal engraving, ideal for jewelry-making projects.
Higher Isn’t Always Better — Match Your 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.
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.

|---|---|---|---|
| Beginners | Ortur R1 | 5W LU3-5B 1.3W IR LR4-1A | Basic engraving on wood/paper |
| Beginners | Ortur LM2 S2 | 5.5W LU2-4 SF | Ultra-high value for money, fine engraving on thin wood/bookmarks |
| Beginners | OLM3 LE | 5W LU3-5 | Basic engraving on wood/paper |
| Craft Enthusiasts | Ortur LM2 Pro S2 | 10W LU2-10A | Combines engraving and cutting functions with excellent results |
| Craft Enthusiasts | Ortur R2 | 20W LU3-20A | Batch engraving + color stainless steel creation |
| Small-Scale Entrepreneurs | Ortur LM3 | 40W LU3-40A | Compatible with 40W module; LM3 focuses on high-efficiency engraving |
| Small-Scale Entrepreneurs | Ortur F10 | 40W LU3-40A | F10 focuses on continuous cutting of long materials; both handle thick materials and non-pure metals in batches |
| Professional Workshops | Ortur H20 | 40W LB4-40A 2W IR LR4-2B | 40W cuts various thick materials; 2W IR engraves pure metals; covers multiple scenarios without module replacement |
| Metal Customizers | Ortur LM3 | 1.3W IR LR4-1A 2W IR LR4-2B | Ultra-fine metal marking (rings/electronic components), jewelry engraving |
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".
