Lasers are usually used in large and medium-sized industrial fields, such as manufacturing. However, with the two-way development of economy and science and technology, many craftsmen have the demands for the actual use of laser to complete the engraving speed and accuracy that is difficult to achieve manually so that at fiber laser engraving machine was born for original craftsmen, then desktop laser marking machines have emerged. xTool F1 Ultra and EM-Smart's new EM-Smart Dual "20W Fiber + 20W Diode" laser engraver is one of the most cost-effective desktop laser engravers available today. Whether you are a laser engraving enthusiast or a craft entrepreneur, you will definitely hesitate between the two. This blog will compare the product selling points and technical features of xTool F1 Ultra and EM-Smart Dual.

1. Quick Comparison

2. Engraving Speed & Accuracy

• xTool F1 Ultra: Engraving speed of 10, 000mm/s, relying on 16MP smart camera to achieve autofocus and 3D surface modeling, engraving repart accuracy of 0.005mm, fine lines (such as 0.1mm text) edges may appear burrs.
• EM-Smart Dual: Engraving speed of 10, 000mm/s, engraving repart accuracy of only ±0.002mm, support electric & manual focus, can engrave a minimum line width of 0.06mm. In addition, EM-Smart Dual 20W laser engraver has a character height of 0.9mm at the engraving and cutting level and a minimum kerf accuracy of only 0.15mm, which can be easily achieved whether it is laser marking on large surfaces or fine engraving on precision parts.

3. Material Processing

The wavelength of fiber lasers (1064nm) is easily absorbed by metals, making the two  ideal fiber laser engraving machines for metals. But fiber lasers' wavelengths are not easily absorbed by common materials such as wood, paper and fabrics. That's where the EM-Smart Dual 20W laser engraver and xTool F1 Ultra come in handy, for EM-Smart Dual 20W laser engraver is equipped with both diode laser and fiber laser that can process more than 300 materials.

In the process of engraving materials, as mentioned above, at the same engraving speed, the accuracy of engraving and cutting of EM-Smart Dual 20W laser engraver is more precise than xTool F1 Ultra.

It can be seen that EM-Smart Dual performs better in laser cutting.

4. Working Area

• xTool F1 Ultra has an operable area of 220mm*220mm, and its maximum operable area can reach 220mm*500mm, but to achieve this, a xTool Conveyor belt is required.
  
• EM-Smart Dual's basic operable area is 230mm*230mm, which is about 135% of the operable area of ordinary laser marking machine. The larger operating area can help users achieve better engraving effect.At the same time, comparing the maximum working heights, the maximum working height of xTool F1 Ultra is 145mm, and the maximum working height of EM-Smart Dual can reach 150mm.
  

5. Laser Engraver Software

• xTool F1 Ultra self-developed XCS integrates AI design tools and material presets, and is compatible with LightBurn (cost extra). It is user-friendly for beginners, but if you need to perform advanced engraving or other actions, you still need to rely on LightBurn to achieve it, and users feedback that it takes time to debug complex surface parameters, so you need to rely on the official case library.
  
• EM-Smart Dual 20W laser engraver comes standard with free EzCad software (supports 14 languages), built-in metal processing parameter library, no need for frequent debugging; free LightBurn is also the standard, suitable for users at all stages. Its 14-language interface and pre-calibrated parameters save professional users debugging time.
  

6. Safety Guarantee

Both are equipped with laser engraver enclosure and emergency stop knobs, while wearing goggles to further reduce light damage during operation. In terms of machine connection, EM-Smart Dual only needs to connect its own three cables (Power Adapter, USB Cable (Type-B), USB Cable (Type-C)), which greatly reduces the trouble in the process of connecting the device to the machine. xTool F1 Ultra is also similar to DUAL in this regard.

7. Warranty

• xTool F1 Ultra provides users with a 12-month warranty period. If you need to extend the warranty, you need to pay an additional fee to extend it to 24 months.
  
• EM-Smart Dual 20W laser engraver provides users with a two-year warranty for fiber lasers and a one-year warranty for diode lasers.

Fiber lasers (2-year warranty) have been rigorously tested and verified for years to ensure long-term stability. With a life of more than 10,000 hours and a low failure rate, fiber lasers are suitable for industrial scenarios and provided with 2-year full warranty protection. In contrast, diode lasers (1-year warranty) are more suitable for lightweight applications such as scientific research and medical treatment due to their large blue light loss and short life, and their 1-year warranty scheme is more cost-effective. The warranty duration is directly related to the product price, and users can choose the adaptation scheme according to the use scenario.

8. Conclusion

Warranty does not represent quality, all products are delivered through the same rigorous reliability testing. Through the above comparison, EM-Smart Dual is the first choice for industrial users with professionalism and efficiency, while xTool F1 Ultra occupies a creative market place with flexibility. On the core track of metal engraving, EM-Smart Dual 20W laser engraver redefines the value benchmark of desktop laser engraving machine with "industrial precision + affordable price". Its ultra-fine repart accuracy of ±0.002mm and multi-material deep cutting beyond its peers make it the first choice for jewelry customization, industrial parts and medical device compliance marks. For users pursuing professional-grade metal processing, it is not only a flat replacement for xTool, but also an optimal solution beyond expectations.
