Applications

CNC Industry

Ideal for CNC applications, the PLH3D-Series is tolerant to vibration and its PCB cover is resistant to metal chips. LaserDock accessory makes the laser head a plug and play device while milling in dust or working with liquid cooling systems. It is easy to integrate the laser head with the machine due to the low supply voltage and small size compared to a CO2 laser. Another advantage is its price which is much lower compared to other solutions available on the market. All the products from PLH3D-Series accept various input control signals including PWM spindle signal, TTL and analog. OEM solutions are also a possibility, allowing an engraver add-on to be offered. For those working only with metals, there is good information that Opt Lasers 6W laser heads can mark stainless steel which is one of the most commonly used materials in construction and machine production.

3D Printing Industry

These days 3D printing technology is one of the most used in prototyping. Every year 3D printers are getting more and more commonly used by RND teams for prototyping and custom order production. Laser allowing to cut and engrave on a wide range of materials adds immense possibilities for 3D printers, rendering them even more versatile in the RND sector. Additionally, 450 nm light allows engraving on many colors of a filament. Another advantage is the unit’s compatibility with a wide range of signal inputs including TTL, PWM, and analog. Its wide voltage supply range (12 – 24 V) and lightweight (210 g, 7.4 oz.) make it compatible with most 3D printers. Various OEM options and solutions are available.

Rubber and Soft Material Processing Industry

The small size of the PLH3D Series allows implementing the laser head even in high part density machines such as rubber cutters. PLH3D Series is equipped with a high-power fan that removes dark smoke, which is especially useful for the machines in question. The long lifetime of the laser source (>10k hours) is ideal for machine applications requiring high reliability and consistent performance. Additional tension given to the material during cutting greatly increases the speed of the cutting process. This solution is used for instance in wheel weight stickers. The dark color of the sticker allows processing the surface faster when cutting or adding serial and part numbers.

Fabric Industry

High absorption of blue light enables fast cutting of materials without affecting the protection layers used for fabric cutting. Enough focus depth allows cutting of thicker fabrics and the ones with irregular surface structure. High power density makes it possible to cut fabrics slightly reinforced with carbon and nylon fibers. A lot of thin materials used in the production of tents, kites, and bags can be cut with the speed up to 60 mm/s which gives the economical advantage over CO2 lasers.

Woodworking, Arts, Crafts

450 nm blue light is highly absorbed by various types of wood allowing patterns, images, serial numbers or initials to be quickly marked. It is easy to customize the shade and line width or depth by adjusting the intensity of the light or the focus. The integrated high-power fan quickly removes any smoke and a LaserDock accessory allows simple detachment for use in dusty environments. Low operating voltage makes it easy to connect without using external power supplies and even if needed the solution is very space efficient. Thanks to the high power of the PLH3D-6W it is possible to engrave images pixel by pixel where the pixel size may be as small as 1 by 1 mm. This allows achieving enormous speed while engraving big images in grayscale or black and white. The PLH3D-Series’ compact form and light weight allow it to be compatible with nearly any 3D printer or CNC machine. Worth mentioning is also its cost-effectiveness. In general, the beam is capable of cutting cardboard, balsa, thinner woods, fabrics or plastic. Also, high-quality 3D surface profiles can be created in wood with this laser.

Stationery, Greeting/Business Cards

The greeting and business card industry appreciates our solutions to create patterns by fast marking or cutting of cardboard, paper, plastic, and special engraving laminates.

6W power of blue light allows reaching 80% of the speed of the 10-12 W CO2 laser tube commonly used in this industry. Painted glass can also be engraved. units Due to a small size and lightweight, our units fit most machines and allow to repair old CO2 machines by equipping it with a modern 450 nm light source like our PLH3D-6W.

CO2 Machines Repair/Improvement

Semiconductor engraving laser head technology is just about to take place of the old CO2 solution. In some situations, CO2 is the only choice for now but every month new market areas are taken over by 450 nm lasers. Many customers and machine repair services reported having been using Opt Lasers products in the old CO2 machines. Additionally, the adaptation in there is much simpler, faster and cheaper than buying a new laser tube.

PCB Prototyping

As a result of creating single layer PCBs just in minutes, the acceleration of product development can be easily achieved. What is more, with the proper preparation of two-layer PCBs are also easy to produce. Created in minutes without special UV layer printed circuit boards can be used in many custom-made products or prototypes reaching the accuracy of 0.15 mm (6 mil). Another significant advantage of the laser head solution over the UV exposure method is the need to use only the black spray. The copper layer needs to be painted and then removed from the areas where it is unwanted. Black color and a thin layer of the paint additionally speed up the process of preparing the laminate for etching.
