The Many Advantages of Laser 3D Marking

The Benefits of Laser 3D Marking

Speed. High Quality. Durability. Flexibility— those are just a few of the key benefits of 3D laser marking.  In recent years, laser marking systems have experienced strong growth in manufacturing processes. Automation and marking flexibility are key contributors for this growth. More specifically, the need to identify parts in automatic manufacturing processes and the flexibility to mark on a two-dimensional field as well as on different heights, curved or complex surfaces called 2.5D or 3D laser marking. This blog will touch on the many benefits of 3D marking as well as the recommended solutions to achieve high-quality laser marking.

Adaptation in the Manufacturing Industry

Many manufacturing systems are rapidly adopting 3D laser marking due to its increased speed, efficiency, and complex marking capabilities. Some will say this (fairly) new process is disrupting the industry and bringing many advantages to its users. The ability to mark any target surface on complex parts in a fast and durable manner is the most preeminent advantage. Apart from durability and high-performance, 3D marking can reduce job set up time by marking on different surfaces, and provide exacting, micron accuracy ensuring repeatability and reliability.

 Markings are Incredibly Flexible

Laser 3D marking can be achieved in any surface and materials such as bare, coated, anodized and plated metals. In each case, the work can be done with incredibly fine detail. Along with the classical applications of such systems (marking of industrial parts, souvenirs, jewelry), 3D marking is gaining popularity due to its wide application possibilities, precision image quality, high productivity and flexibility of the process. In overall performance, 3D marking is superior to other technologies.

Elements of a 3D Marking System

Functionally, there are two main elements to a laser 3D marking system. The first is a fast Galvanometer for 3D marking and rapid focal length adjustment. For example, Cambridge Technology’s 3-axis scan with integrated Z-axis can yield a range of up to ±400 mm from the nominal focal distance, delivering ultimate synchronization between X, Y and Z axis. The second and the most important element of a 3D laser marking system is a high-performance marking software that can import a 3D CAD drawing of the workpiece and the desired pattern to be marked in 3D. Compatible lasers for 3D marking are CO2 and Fiber lasers.



Cambridge Technology’s ScanMaster Designer software is designed for complex jobs like 3D marking. Its highly sophisticated yet easy-to-use features enables users to display allowable 3D marking field and then either wrap or mark pattern on 3D CAD drawing of a workpiece seamlessly. The combination of a 3-axis scan head and a highly graphical user interface software allows users to produce high-quality 3D marking with high-speeds and durability. Apart from high-performance, the ScanMaster Designer also offers higher accuracy calibration different than traditional scaling 2D calibration into pyramidic algorithm.  Other key features include 3-axis control free of dongle, calibration accuracy and 3D modeling and marking flexibility.
