Full set including all parts needed to mount the PLH3D-6W-XF laser head on the Stepcraft CNC machine. Set is including PLH3D Series Adapter, Air Nozzle, Lens and 450 nm Safety Goggles with CE certificate. 

Included parts

- PLH3D-6W-XF Laser Head

- PLH3D-6W Nozzle

- PLH3D Series Adapter for Stepcraft

- Safety Goggles

- Beam Focus Adjuster

- High-resolution Engraving Lens with PLH3D Lens Regulator (Factory-preset)

- High-efficiency Engraving Lens


Note: you may receive the laser safety goggles with a slightly different frame. However, the Optical Density rating, as well as Working Wavelengths, will be the same.

Advantages of the PLH3D-6W:

- Simple installation in 3D printers and CNC machines

- Accepts a wide range of power supplies

- No additional cooling required

- Driver integrated inside the laser head

- Compatible with accessories for ease of use

- OEM customization available for of 3D printer and CNC machine companies


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

Improved Heat Sinking

This lightweight 220 g (7.8 oz) 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. 


The PLH3D 6W laser head 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 the case on occasion there appears the voltage higher than 5 V. Despite everything, this input should not be used with higher voltages due to the 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 the copper layer of plates after a photosensitive paste is applied.
