In modern industrial processing, laser marking machines have become essential equipment due to their efficiency and precision. The most commonly used laser marking machines on the market include fiber, CO2, and ultraviolet (UV) types, each suitable for different materials and processing needs. Choosing the appropriate type is crucial for ensuring marking quality and operational efficiency. Foster Laser has demonstrated outstanding performance and deep technical expertise in the laser marking industry. Its wide range of products fully meets the diverse needs of customers across various sectors.

💎Selection Criteria for Three Types of Laser Marking Machines
FIRST Fiber Laser Marking Machine
Fiber laser marking machines use optical fiber as the medium for laser generation and are categorized as low thermal laser sources. Their core advantage lies in exceptional processing performance on metal materials. When engraving metals, fiber lasers can perform high-speed marking due to their high energy density, which rapidly induces physical or chemical changes on the metal surface to create sharp markings. Compared to other types of laser marking machines, laser printer for metal also offer lower overall equipment cost and excellent cost-effectiveness.
Foster Laser’s fiber laser marking machines are further optimized in performance, with unique optical path designs and advanced control systems that ensure faster marking speeds and higher precision.
SECOND CO₂ Laser Marking Machine
CO₂ laser marking machines operate at a wavelength well-absorbed by materials like wood and paper. When applied to wood, the laser reveals natural textures and patterns, making it widely used in wooden handicrafts and furniture branding. These machines are also ideal for organic materials such as paper and leather. Furthermore, CO₂ lasers can be used on glass, where controlled laser energy creates micro-cracks on the surface to form patterns or text.
Foster's CO₂ laser marking machines excel in such applications, equipped with high-power laser sources and precise laser control systems, enabling accurate processing of materials of varying thickness and composition.
THIRD Ultraviolet (UV) Laser Marking Machine
Due to their exceptional versatility, UV laser marking machines are often referred to as "universal laser markers." Operating at a short wavelength of 355 nm, laser engraving machine with coloring can process material surfaces with minimal heat generation. They are ideal for delicate materials such as plastics, acrylic, and transparent glass, delivering ultra-fine marking results suitable for high-end product customization.
Foster UV laser marking machines utilize advanced UV laser technology, offering excellent beam quality and stability to meet the most demanding industrial marking requirements.
It is widely used in many fields, including rust removal, paint stripping, historical artifact cleaning, and pre-treatment of metal surfaces.

💎Key Technical Components and Details in Laser Marking Systems
✨FIRST Marking Range and the Role of Field Lens and Laser Source
The marking range is primarily determined by the combination of the field lens and laser power. The field lens focuses and scans the laser beam across the workpiece surface, defining the effective marking area. Generally, longer focal length lenses provide larger marking areas, but reduce energy density. For instance, a 30W laser marker should typically use a field lens not exceeding 150mm to avoid issues like oversized laser spots and diluted energy, which can lead to weak or unclear markings.
When performing deeper engraving or light cutting—where higher laser energy is required—a smaller focal length lens concentrates the beam, achieving better results. A 100W laser marking machine can accommodate marking areas up to 400×400mm, but optimal lens selection still depends on specific materials and application scenarios.
✨SECOND Function and Limitations of the Lifting Platform
The lifting platform adjusts the distance between the laser head and the workpiece, adapting to materials of varying thickness. Generally, the platform can accommodate materials up to 50 cm thick. If the material exceeds this limit, the laser cannot accurately focus on the surface, and marking cannot be completed effectively. Proper height adjustment is essential before operation to ensure precise laser focus and optimal marking quality.
✨THIRD Importance of the Mainboard
The mainboard is the core control unit of a laser marking machine, responsible for regulating key parameters such as laser output power, frequency, and pulse width. These parameters directly influence the marking depth and overall quality. Through precise circuit design and software algorithms, ezcad laser marking machine enables accurate laser control.
Different materials and processing requirements necessitate fine-tuning of laser parameters via the mainboard. Harder materials require higher power for deeper engraving, while softer materials call for reduced power to avoid overprocessing. The performance and reliability of the mainboard are therefore critical to overall machine stability and processing results.

👏👏When selecting a desktop fiber laser marking machine, it is vital to consider material characteristics, processing requirements, and equipment specifications holistically. Understanding the advantages and applicable scenarios of each laser type, configuring the appropriate field lens and lifting platform, and ensuring a high-performance mainboard are all essential to achieving optimal results and meeting diverse industrial needs.
With deep technical expertise and a commitment to innovation, Foster Laser continues to deliver cutting-edge laser marking solutions that drive productivity and precision in modern manufacturing.
