"3DMart Demo Units" are laser modules previously used only for customer demonstrations and printing services, operated and maintained by professional engineers and internal staff. These modules are still functioning well and are not repaired machines, defective machines, or customer machines.
To stay at the forefront of the industry, we must continuously update and personally use new models. We pay great attention to the maintenance of our laser modules. In addition to replacing parts and consumables, our engineers perform regular cleaning and maintenance. These used laser modules are still in excellent condition and working well, so we offer them to you at a discounted price as another option.
All used-but-good products are thoroughly tested and refurbished before sale. As these laser modules are not new, their appearance may show some signs of use, color variations, minor scratches, etc. However, these cosmetic imperfections do not affect any of the functions inherent to the product model, and they can still provide stable printing and high-quality results. We also offer a three-month warranty and return them to you at a more favorable price. The quantity of these machines is very limited, so please seize this "good opportunity"!

2. Blows away smoke and prevents charring
3. Keeps the laser lens clean
4. Smoke is discharged through the mesh table

You can achieve large projects such as maps, furniture models, and door signs. The Ray can be raised with cylindrical feet, allowing you to handle laser jobs up to 160mm thick.

Supports working speeds up to 500mm/s and sustained operation.


Supports functions like serial connection, motion control, and G-code generation. Get a full set of recommended parameters for common laser materials in LightBurn.

Luban offers a rich library of preset templates, including common patterns, shapes, and icons, allowing you to complete designs in minutes.

The enclosure panels, made of brown acrylic, are specially designed to protect you from laser hazards. The embedded door detection sensor automatically stops laser operation when the door is opened.

Turn on the exhaust fan to expel all smoke and dust. You can further connect it to our air purifier to filter harmful chemicals.

Calibration can be easily completed in just three steps.

The upcoming rotary module can handle more circular, conical, spherical, cylindrical, and other objects in daily life.
