Description
3D Auto Focus Fiber Laser Marking Machine Introduction
3D Auto Focus Fiber Laser Marking Machine is an advanced laser marking system designed to engrave, etch, or mark on 3D surfaces with high precision and efficiency.
It uses auto-focusing technology to automatically adjust the laser beam's focus based on the varying depths of the object, enabling consistent and distortion-free marking on uneven, curved, or multi-level surfaces.
What is the difference between 2D/2.5D/3D machines?
2D laser with 2D galvo scanning head and EZCAD2 control card, EZCAD2.1 4.11 version software.
It can mark flat metal and some nonmetal surface , deep engraving metal and cutting some thin metals.
2.5D laser means 2D laser + motorized Z axis + EZCAD3 software.
Based on the common 2D laser, the latest 2.5D machine is composed by the motorized Z axis and EZCAD3 software, mainly used for STL file metal mold coin relief engraving etc + All features of 2D machines.
3D laser is the most comprehensive machine, which also have the motorized Z axis and EZCAD3 control card, plus a 3D Dynamic focus scanning head , it can be used for curved surface (app 120 degree) marking without rotary, can be used for metal mold and coin relief engraving, what's more, it can be used for big format like 300*300mm metal deep engraving.

FAQ
1. Q: Which is better manual focus or autofocus laser?
A: An auto-focus laser engraver offers faster adjustment over a manual machine if you are working with multiple types of materials with varying thicknesses.
2. Q: What are the advantages of auto-focus?
A: Autofocus provides convenience and speed.
It is often the go-to method in general digital cameras for many photographers, especially when dealing with fast-moving subjects or a chaotic scene.
3. Can it mark on curved or irregular surfaces?
Yes, the 3D functionality allows precise marking on curved, sloped, and uneven surfaces by adjusting the laser focus dynamically.
4. How does 3D marking differ from traditional 2D marking?
3D Marking: Handles uneven, sloped, and multi-level surfaces while maintaining consistent quality.
2D Marking: Limited to flat surfaces or surfaces with minimal variation in height.
5. Can it handle high-volume production?
Yes, its high-speed operation and precision make it suitable for industrial production lines and large-scale projects.
