Professional Engraving Laser head offers high power and excellent ease of use


Our second generation PLH3D 6W professional engraving laser head offers high power and excellent ease of use. Improvements to the electronics allow the laser head to be powered by 12 – 24V, enabling compatibility with power supplies of nearly all CNC machines and 3D printers.


PLH3D-6W-XF Professional Engraving Laser head offers high power and excellent ease of use.


The focus distance can be quickly set or changed via the included lens adjuster (no additional tools). The driver of the unit is integrated directly on the laser head. This greatly increases the maximum modulation frequency and allows longer cables to be used.

Control Inputs

The laser head has two separate controls. Input #1 accepts 0 – 5V for analog power modulation. Input #2 accepts 0 – 24V for TTL/PWM and turns on the laser when the voltage exceeds 2.5V. (Input #1 can also be used for PWM if #2 is dedicated for TTL only.)

Improved Heat Sinking

This lightweight 220g (7.8oz) laser head requires no additional cooling. The body acts as a heat sink, and the fan design allows it to function as an air nozzle protecting the lens from smoke, while also cooling the laser head. Performing tests on several prototype designs allowed us to optimize the heat sink’s shape and enable efficient cooling while maintaining the module’s notably small form factor.

Accessory for Smoke

The laser head allows engraving or cutting of materials such as wood, stainless steel, paper, leather, cardboard and many others. For materials that generate smoke when engraved or cut, we offer an optional nozzle that is attachable to the front of unit via magnets built into the laser head (see accessories).


The PLH3D 6W incorporates a thermal protection system that protects the laser diode from overheating to maintain its lifetime. The unit is designed to automatically shut off when the housing temperature exceeds 47C. The analog input is protected by a 5V Zener diode in case on occasion there appears the voltage higher than 5V. Despite everything, this input should not be used with higher voltages due to risk of damage. The laser diode is protected via a Schottky diode, which protects it from a reverse voltage and ESD. In addition, the integrated driver is fully covered to protect it from metal chips in a CNC machine environment.

Alternative functionality
Besides the standard functionality, the small beam spot allows the possibility of using this product for rapid PCB prototyping. This is done by illuminating copper layer of plates after a photosensitive paste is applied.

Remember that it is not a toy.
Laser radiation is dangerous even when scattered or reflected from any surface.
Always use proper protection laser filter on your CNC machine dedicated to 430 – 480nm in order to avoid reflected radiation.
Never point laser head at people or animals.
Do not touch the beam, it may cause burns or other injury.
Do not stare at the beam or the beam spot while the material is being cut.
Laser radiation – Avoid eye or skin exposure to direct or scattered radiation.
Class 4 laser product.
