PLH3D-6W-Series Engraving and Cutting Laser Heads
About PLH3D-6W-Series Engraving Laser Heads
PLH3D-Series were created as a series of compact and light laser heads. Their versatility allows to use them with almost all CNC machines available on the market. Due to the fact that their size and weight (70 – 220 g) have been significantly reduced, they are perfect even for small and delicate mechanisms. High-speed driver built inside the laser head protects it against inductance effects and allows to switch on the laser diode faster. Nevertheless, the most important thing is that the length of the wire between the power supply and laser head can reach a few meters without causing any problems.
PLH3D laser heads do not require any additional cooling what makes them perfect for use in machines made of composites, wood or plastic. Thanks to specially adapted optics, the beam spot size that provides very high power density allow to cut and engrave many types of materials. PLH3D laser heads are a great substitute for CO2 CNC lasers and can work with special engraving laminates, laser foils and many standard materials such as wood, rubber, cardboard, fabrics, leather, painted/anodized metal. 6W lasers are also great for stainless steel and titanium marking.

Woodworking - Cutting and Engraving Wood
Blue laser engraving can produce a detailed pattern with round edges as well as darken the color of the wood. Laser engraving can be used to engrave a logo or a photo, which can’t be done with milling bits. With PLH3D-6W, you can laser engrave wood and wood-based materials, including cork, chipboard, particleboard, alder, cherry, maple, MDF, basswood, balsa, veneers, medium-density-fiberboard and high-density-fiberboard.
Cutting Textiles and Thin Synthetic Materials
The high absorption of blue laser light for numerous materials enables fast cutting without damaging protection layers used in textile cutting. Blue laser cutting and engraving are suitable for diverse types of textiles including Cordura™, Alcantara, felt, 1080 denier nylon, jeans, short-staple fiber cotton, wool, tartan, fleece, white polyester, softshell, silk, lace and linen. High power density enables laser cutting textiles with carbon-reinforced yarn and nylon-reinforced yarn as well as white textiles. Many robust materials used in the production of tents, kites, and bags can be cut at 60 mm/s.

Accessories
LaserDock – Speeds up your work and keeps your laser clean
An effective solution for both large and small CNC machines and 3D printers, this magnetic docking station allows the PLH3D-6W Series laser for engraving to be quickly attached or removed. This facilitates quick access for CNC milling or 3D printing. By protecting the laser head from plastic or wood dust from your printer or CNC mill, it can extend the lifetime of the engraving laser and reduce maintenance. It also allows you to take advantage of the entire working area of your 3D printer or CNC machine.
High-Pressure Air Assist Nozzle - Speeds up laser engraving and cutting up to 6 times
Being compatible with the XF+ Laser Head with or without the µSpot Lens Upgrade, the High-Pressure Air Nozzle is a priceless asset for laser cutting and engraving. Not only does it speed up cutting and engraving with laser by up to 6.5 times, but it also substantially improves the attained quality of the processed material. With the High-Pressure Air Nozzle your yield will have noticeably enhanced quality with uniform and well-defined features. Our High-Pressure Air Nozzle will also protect your optics from smoke and dust particles, extending the intervals between subsequent lens cleaning routines, and boost user safety. Furthermore, the length of the High-Pressure Air Nozzle can be adjusted for different material thicknesses by +8/-4 mm for the XF+ Laser Head or +5/-4 mm for the XF+ Laser Head with the µSpot Lens Upgrade.
PLH3D-CNC Adapter - Easy connection to any CNC machine
Many types of CNC machines and 3D printers with different control voltage standards and levels available on the market may be used to control the PLH3D head. The PLH3D-CNC Adapter converts all these signals to the standard compatible with the PLH3D head. The PLH3D-CNC Adapter contains widely used industry-standard screw connectors. A dedicated desktop low-noise power supply unit assures compatibility and reliability as well as eliminates problems caused by using third-party power supplies. The general status (power, armed, laser working) may be checked at a glance by watching three LEDs.
