Advantages of 3D Laser Marking Machine
● Flexibility
The 3D laser marking machine can mark various shapes and sizes of curved products, such as oblique planes, segment gaps, stepped surfaces, cylinders, circular cones, and spheres. lt can also mark different depths of the product, allowing for greater design flexibility. This allows companies to mark more intricate patterns and graphics on their products, which can help them attract customers.
● Handle curved surfaces
Another significant advantage of 3D laser marking machine is its ability to handle curved surfaces. Unlike traditional 2D fiber lasers, which require complex adjustments to perform curved engraving, the 3D laser marking machine can trace the focus of deep curves in real-time. This can greatly improve the processing efficiency and accuracy of curved surfaces.
● Handling large format products
In addition to its ability to mark curved surfaces, the 3D laser marking machine can handle large-format products, and it is very efficient in terms of production speed. This is because the 3D laser marking machine can quickly change the focal length of the laser beam and adjust its position, thereby allowing it to process more workpieces in less time.
● Easy to use
The 3D laser marking machine is easy to use and is compatible with most popular software systems. lt can be used in all kinds of production line, visual positioning, deep-carving and other applications. The 3D laser marking machine can be configured to meet the requirements of a variety of materials, such as metals, plastics, glass, and wood.
How 3D Laser Marking Machine Works
3D laser marking machine is the use of high energy density laser to partially irradiate the workpiece to make the surface material vaporize or undergo a chemical reaction of discoloration, thereby leaving a permanent mark. 3D laser marking machine can mark various characters, symbols and patterns, etc., and the character size can even reach the micron level.
The laser beam used for laser marking is generated by a laser, undergoes a series of optical transmission and processing, and finally is focused by an optical lens, and then deflects the focused high-energy beam to a designated position on the surface of the processed object to form a permanent concave mark.
The traditional 2D laser marking machine adopts the post-focus method, which generally only allows plane marking within the specified range. The emergence of the new 3D laser marking machine has solved the long-term inherent defects of the 2D laser marking machine.
The working principle of candlelight imaging is to control and move the dynamic focusing mirror through software, and to expand the variable beam before laser focusing, so as to change the focal length of the laser beam and achieve precise surface focusing processing of objects at different heights.
The Difference Between 3D Laser Marking Machine and 2D Laser Marking Machine
● The scope of application is different: Traditional 2D laser marking machines can only perform flat marking, while 3D laser marking machines can mark or engrave on 3D objects such as curved surfaces and irregular surfaces. Achieve a more three-dimensional and fine marking effect.
● The marking effect is different: 2D laser marking machine can only do monochrome outline marking; 3D laser marking machine can achieve richer patterns and effects, such as deep engraving, embossing, color filling, etc.
● Different processing efficiency: Traditional 2D laser marking machines are more suitable for batch processing of materials, and can only mark on one plane at a time. For marking with different depths and heights, it is necessary to switch the processing area multiple times, which takes a long time. The 3D laser marking machine can achieve continuous processing in three-dimensional space through height adjustment during the processing process, and the processing efficiency is higher.
● Different cost: Due to the technology, 3D laser marking machines are usually more expensive than 2D laser marking machines, so for customers who need higher accuracy and wider application, choosing 3D laser marking machines may be a better choice.

Factors to Consider When Selecting 3D Laser Marking Machine
● The Power Of The Laser
The power of the laser is measured in watts (W). The longer the wattage, the more influential the laser. For most applications, a laser with a power of 30W is more than sufficient. However, if you're looking to mark metals or other rigid materials, you may need a laser with a higher power.
● The Wavelength Of The Laser
The wavelength of the laser is measured in nanometers (nm). The shorter the wavelength, the more precise the laser beam will be. Many lasers marking machines come with a wavelength of 1064nm. The 1064nm wavelength is ideal for most marking applications.
● The Spot Size Of The Laser Beam
The spot size is measured in micrometers (μm). The smaller the spot size, the more precise the laser beam will be. Some laser marking machines have a spot size of less than 10μm. That's incredibly precise! As you can see, there are many factors to consider when choosing a laser marking machine. But once you understand what you need, you should be able the find out the perfect device for your application.
● The Marking Area Of The Machine
The marking area is measured in millimeters (mm). The larger the marking area, the more materials you'll be able to mark at one time. An industrial laser marking machine typically has a marking size of 300mm x 300mm. Other devices may have a smaller or larger marking area.
● The Type Of Laser Marking Machine
There're two main types of 3D laser marking machines: desktop and industrial. Desktop machines are smaller and more affordable, while industrial machines are larger and more powerful. You should choose the type of machine based on your specific needs. A desktop machine will be more than sufficient if you're only looking to mark small items. But an industrial machine will be necessary if you want to keep more oversized items.
● Safety Features
Given the nature of 3D laser marking machines, there's always a risk of fire. Enclosed machines equipped with fire alarms and smoke purifiers are ideal.
● Material Compatibility
Define the materials you want to use. Different 3D laser marking machines excel at engraving different materials. Make sure the machine you choose is compatible with production efficiency and the materials you plan to use.
How to Maintain 3D Laser Marking Machine
● Regular Cleaning of the Lens
Over time, dust, debris, and other contaminants can accumulate on the laser lens, reducing its efficiency and accuracy. To maintain optimal performance, clean the lens regularly using a microfiber cloth or specialized lens cleaning solution. Ensure that the cleaning is done gently to avoid scratching the lens surface.
● Lubricate
The marking head, axis rails, and any other moving parts require proper lubrication to avoid wear and tear. Use the recommended lubricant to keep these parts functioning smoothly. Regularly inspect these areas and lubricate them as per the manufacturer's guidelines to prevent friction and extend the machine's lifespan.
● Software and Firmware Updates
The machine's performance can be enhanced by keeping its software and firmware up to date. Regularly check for updates from the manufacturer and install them to benefit from new features, bug fixes, and performance improvements. Updated software can also ensure better compatibility with newer operating systems and 3D design files.
● Laser Source Maintenance
The laser source is the most critical component of the 3D laser marking machine. Periodically check the power output and performance of the laser. If you notice any reduction in marking quality or power, consult the manufacturer's guidelines on adjusting or replacing the laser source.
● Electrical Connections and Power Supply Inspection
Periodically inspect all electrical connections and the power supply to ensure they are secure and free from wear. Loose or damaged connections can cause power fluctuations that may affect the performance of the machine or even lead to damage.
FAQ
Q: Do you need to passivate after 3D laser marking machine?
