Two power levels are available for this model, 33W and 55W. Besides, Nova Series are also excellent choices you may look at. 

2. Fiber Laser Engravers

Technically, Fiber Laser engravers are a type of solid-state laser machine that uses seed lasers. This type of laser engraver amplifies the laser beam using glass fibers. Since the fiber laser can produce a minimal focal diameter, the cost of the technology is considerably high. Therefore, fiber laser engravers can make finer engraving than CO2 Laser engravers. 

Fiber laser engravers offer long service life and require less maintenance. Fiber laser engravers can manage intensities higher than CO2 lasers with the same input power. Due to the flexibility of the fiber laser system, it is easy to apply more functionalities. MOPA fiber laser system is one of the market’s most common fiber laser engravers. 

Fiber Laser engravers are the best choice for engraving metals and thermoplastics. It is also suitable for marking metals by the annealing process. Besides metals and plastics, fiber laser engraves can also engrave wood, glass, acrylic, bricks, etc. As mentioned earlier, fiber laser engravers can be versatile and deal with different materials depending on the power. 

The laser marking aurora series is the best choice for fiber laser engravers from Thunder Lasers. These models come with a working area of 110×110 up to 200x200mm. The power range might vary between 20W, 50W, and 20W MOPA. 

3. YAG Laser Engravers

Like the fiber laser engravers, a YAG laser is a type of solid-state laser. The complete form of YAG is yttrium aluminum garnet which is the host crystal of the system. This host crystal acts as the electron source in the laser engraving process. However, YAG laser engravers are widely famous in most industrial material processing. 

YAG laser engravers are the best for etching metals in bulk order production. YAG laser engravers often etch silverware. Besides silverware, this machine also engraves various materials, such as brass, pewter, acrylic, plastic, steel/stainless steel, and aluminum.

How Laser Engraving for Metal Works?

Lasers are typically bright, monochromatic, and good at directing. It is important to note that laser is different from ordinary light. The laser has high luminous intensity, coherence, and high laser intensity. After the laser is radiated from the laser source, a collection of mirrors transmits and irradiates the laser beam to the material surface. 

The high-intensity laser beams are so powerful that it creates a high temperature when they fall on a specific point on a surface. After that, the particular point quickly melts and vaporizes due to the high-temperature effect. Therefore, laser engraving is fast and accurate that can ensure every sharp detail from a design. Thus, laser engraving for metal is famous in many applications, as mentioned in the previous heading. 

The laser gun moves according to the program given by the operator. It moves at a definite speed based on the requirement of the engravings. CNC, or computer numeric control, is the popular machine language suitable for most automated engraving machines for metal. According to the CNC programs, the X, Y, and Z axis motors rotate as per the design requirements. 

On the other hand, laser engraving software such as the light burn software is very famous for laser engraving for metals. The software allows you to customize the design and control the laser power levels. In some cases, some brands offer their company-made software. But in most cases, the basis of using such software is the same for all.
