PLH3D-6W-Series Cutting and Engraving Laser Heads
PLH3D-6W Versatility and Sustainability
PLH3D-6W-XF+ 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-6W-XF+ 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-6W-XF+ 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.
| Material | Operation | Feed Rate |
| Anodized Aluminum | Marking | 50mm/s (118 IPM) |
| Painted Steel | Marking | 50mm/s (118 IPM) |

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.

Product Features
Powered by Blue Laser Diodes
Unlike infrared light, blue light is more easily absorbed by numerous industrial materials. This directly translates to several advantages including reduced power consumption and more compact heat sinking.
Integrated Control Electronics
In many laser heads that have the diode connected to the diode’s driver via a long cable and the coupling is done with connectors. Long wires are characterized by substantial inductive effects. This results in delays of the diode’s response in relation to the diode’s driver and as extension it also results in blurred lines. Connectors are more prone to disconnections than coupling done via direct soldering. Disconnecting during laser processing can damage the laser head.
Long Lifetime
Opt Lasers laser heads are industry-level grade CNC machine tools. Mechanical parts are made from machined aluminium. Our products are designed with cooling optimization in mind. Investing in the highest quality equipment ensures the best performance and price.
Lightweight Design Mounts to Nearly any CNC Machine
Featuring a lightweight, Aluminum body that makes the laser weight less than 370 g. As a typical CNC spindle weighs approximately 1.8 kg, CNC machines can operate it effortlessly.
Simple Integration
Can be set on nearly any CNC machine since it accepts both analog and PWM CNC signals.
Instant-On Power
No warm-up time
Accessories
LaserDock (Included in the Kits) – 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-XT 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 (Included in the Kits) - Speeds up laser cutting and engraving up to 6 times
Being compatible with the XT and XF+ Laser Head, 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.
Laser Safety Glasses (Included in the Kits) - Ensure the highest quality of protection
These laser glasses can help reduce the probability of light entering the eye from the diffusely reflected laser light. It is important to note that while these laser glasses may be helpful at adding an additional layer of safety for diffusely scattered light, the user should not depend on them to protect against the beam entering the eye, either directly or indirectly. It is necessary to take additional precautions when working with lasers, receive proper training on how to do so and not depend on equipment as an alternative to safe practices.
Other accessories (Included in the Kits) - To make your Opt Lasers Kit plug & play
With these accessories, it is a plug & play kit. Height Reference - helps you set your working distance, power adapter with AC adapter to allow you to plug into all outlets (US, AU and Europe), wiring and screw set to connect everything together and mount to connect the machine.
PLH3D-CNC Adapter (Included in the Kits) - 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.
