Notes:
- 1,2The table above is a general guideline for laser engraving and cutting capabilities of different materials with our range of blue laser heads. The practical performance may however vary depending on the particular material’s manufacturer, material type (or alloy in the case of metals) as well as its production process, which influences its composition, thermal conductivity, and surface roughness among other important factors. Exact materials of interest should be tested for final verification. In addition, the material’s color is of great importance as well. Darker colors yield better results, while lighter or semi-transparent colors are worse. Blue colors might often be difficult and sometimes even impossible to laser cut or laser engrave. White-colored materials are often also impossible to be laser processed as white materials reflect blue light. For instance, the XF+ laser head can engrave dark stone, while it won’t be able to engrave white stone or marble.
- 3It depends on the density of the glass threads and their thickness.
How to Choose an Appropriate Laser Engraver Based on the Material Type
Metals
The main factor between material types that decides if a particular material type can be easily laser engraved or not is whether the material is metallic or not. Some metallic materials cannot be engraved at all. To engrave metals, ie. to remove a layer of the processed metal, it is recommended to start with a 15 W or higher optical power blue laser head. As of now, PLH3D-15W laser engraver is the best compact laser head on the market capable of engraving steel as well as stainless, carbon, tool and high-speed subspecies of it. It still is not powerful enough to engrave on bare Aluminium, Copper or brass simply because these materials either conduct heat too well or reflect too much laser light. It is possible to laser engrave copper with 30 W (optical power) blue laser heads. XT-50 is another laser engraver that allows you to work with metals, and it does so with outstanding precision (as its 50 µm wide focused beam spot corresponds to >500 real-life DPI ). These two engraving laser heads allow you to laser engrave (not just mark) the metals mentioned above.
If you are satisfied with simply laser marking the metal, you can achieve it on stainless steel and Titanium (but not other metals) with 6 W laser engravers. Laser marking is defined here as changing the color of the metal surface as a result of overheating. Laser marking is however less durable than laser engraving because the depth of the color change is much lower. Laser-marked surfaces can withstand just a few scrubs with fine sandpaper. For this purpose, the XF+ laser engraver with High-Resolution Lenses.
Nevertheless, if you want to do it really fast (>30 mm/s), then you will either need a laser with 15 W of optical power or the XT-50 laser engraver and cutter. Depending on the chemical composition and type of stainless steel you can assume speeds of 0.5 - 2 mm/s, 8 -15 mm/s, or 20-40 mm/s for the XF+ High Resolution Lens,PLH3D-15W respectively.
Wood
When buying a blue laser for cutting and engraving on wood, you often need to decide about its power. Less powerful, 2 W laser is not only cheaper but also allows for more precision laser engraving on wood. The more expensive 6-watt laser can engrave images with large pixels, and can be used where 2-watt version cannot, like cutting hard leather, or marking stainless steel or titanium. 2 W laser can work with a size of the spot of light as small as 0.1 mm, which enables wood engraving of very small details.
Results of engraving heavily depend on wood type. Several parameters need to be taken into account like hardness of the wood, surface and growth rings.
Ceramics
As a general rule, it is recommended to use an image with a resolution of at least 300 dots per inch (DPI) for laser engraving. This will ensure that the laser is able to produce a detailed and accurate engraving, even at small sizes. However, higher resolution images may be necessary for extremely detailed or fine engravings.
By using a high-resolution image and considering the size of the engraving relative to the size of the ceramic plate, you can achieve the best results when engraving with a diode laser. There are a variety of software programs that can be used to create designs for engraving on a ceramic plate with a diode laser.
With PLH3D-XT-50 and it's capabilities to perform engraving with the 500 DPI allows for amazing quality engravings on materials like ceramic tiles. Higher power density reveals new engraving and cutting possibilities. Additionally, engraving and cutting processes are significantly faster comparing to laser heads without anamorphic optics.
Thermoformed Plastics
/PLH3D-15W-Laser-Acrylic-Cutting_fin.jpg)
/PLH3D-15W-Red-Plexi_fin.jpg)
For thermoformed plastics, optical power density is significantly less important than optical power. The more optical power you deliver to the surface being processed, the faster it melts. For this very reason, 6 W laser engraver is a good choice. It is because it is built with the highest power laser diode available on the market. Nevertheless, higher optical power laser engravers and cutters such as 15 or 30 W multidiode laser heads will do an even better job. 2 W is generally not recommended for processing thermoformed plastics but it can do the job if lower cutting speeds are acceptable.
Dangerous Materials
There are many dangerous materials, particularly plastics, for which you should research whether a given material can be safely laser processed before any laser processing takes place. For these materials, you should have a ventilation system set-up in place and well as use an air-assist nozzle to protect the lens if possible. As a result the most suitable laser engraver and laser cutter choices would be:
- Either PLH3D-XT-50 with the High-Pressure Air-Assist Nozzle;
- Or PLH3D-6W-XF+ laser head with the High-Pressure Air-Assist Nozzle;
- Or PLH3D-15W which has an air-assist nozzle built-in as a standard feature.
It is a good practice to have a ventilation system set-up for laser processing any plastics and additionally to remove the fumes with additional fan or direct fumex extraction tip from the cutting point. Remember that fumes are dangerous not only to humans, certain materials produces corroding gas or other substances that can influence your machines performance over time.
White-Colored Materials
Unlike thermoplastics, white materials require a high optical power density laser head in order to be laser engraved or laser cut. The higher the optical power of your laser engraver and laser cutter is, the higher variety of materials you will be able to cut. Hence the best choice for such materials is either PLH3D-15W or XT-50 if ultra-hd precision is preferable.
Other Types of Materials
As a general rule, most laser heads can process similar material types. Only a few particular types of materials require your laser engraver and laser cutter to have specific properties. The most common problematic materials were mentioned above.
Other types of materials can be processed with all engraving laser heads that have at least 2 W of optical power, and the main difference in their application would be the throughput obtained.
Choosing Appropriate Laser Head Based on the Material Thickness
The maximum thickness of the material that can be laser cut is determined by a few parameters. The most important factor is the material itself. Secondly, it also depends on the optical power and optical power density of your laser as well as the angle of the light cone. Foams in general are the thickest materials that can be cut with a laser cutter.
As a general rule, PLH3D-XT-50 or PLH3D-15W laser engravers will perform better than XF+ at laser cutting anything thinner than 5-6 mm. For material thicknesses above 8-10 mm it is advised not to use PLH3D-15W, XT-50 or XF+ as they will cause edge burning as a result of light cone angle. PLH3D-15W laser cutter will perform way better than XT-50 working with themoplastics with around 3 times higher laser cutting speed. Meanwhile, the XT-50 laser cutter will perform better at removing thin layers or laser cutting very thin materials where heat dissipation effects have smaller influence on cutting speed. Thus for materials with 8-10 mm thicknesses it is advised to use standard XF+ laser head equipped with either G2, G7 lens or High-Resolution Lens. Standard XF+ can be used to cut quite thick materials up to 40 mm. It can for example be utilized for cutting 40 mm foam in just 4-6 passes. We have also tested cutting 10 mm balsa with PLH3D-6W-XF+ Laser Head, but it is definitely possible to cut even thicker balsa with additional passes.
Compatibility with Various CNC Machines and 3D Printers - And How to Connect Your Engraver
PLH3D-CNC Adapter allows you to quickly connect your laser head to almost any CNC machine, including 3D printers. You may require basic electronics skills to connect it to more complicated controllers. Nevertheless, common controllers such as BlackBox controller, Duet 3D or xPro v4/v5 are quite easy to connect. We also have a controller connection database showing how to connect your PLH3D-CNC Adapter to a wide range of controllers.
CNC Milling Machines
Basically, with the help of the PLH3D-CNC Adapter, it is possible to connect the laser head to almost any CNC machine to turn your CNC machine into a laser engraving machine. One of the most important things, besides the connection, is generating an appropriate G-Code. G-Code for a laser engraver differs from the standard G-Code. The laser needs to be switched off for the duration of any idle movement while a spindle could be left spinning. The two most similar aspects of the laser and spingle g-codes are the power and the rotation speed. The same PWM signal that controls the rotation speed of the spindle can be used to control the laser power of your laser engraver and cutter. Typically, this is done with the S0 - S255 command (0 for 0% power and 255 for full power), but depending on your CNC Software and Controller, you might end up using different values, for example, S0 - S1000.
While it is possible to connect your laser engraver (and cutter) without the adapter, it requires basic electronics skills and an additional power source.
3D Printers
Connecting your laser to a 3D printer is somewhat more problematic than connecting it to a CNC machine. This is primarily caused by the fact 3D printers don’t have a dedicated output for spindle control. As a result, you don’t have a PWM signal designed specifically for the purpose of controlling an additional accessory such as a laser engraver. Nevertheless, a 3D printer has a few additional outputs for heater and fan control. These outputs can be used to control your laser. Using the PLH3D-CNC Adapter adds additional safety features and allows you to use enable signals. While the connection can typically be done in a few different ways, adding PLH3D-CNC Adapter significantly simplifies the connection and allows you to easily connect your laser engraver and cutter without the need for familiarity with basic electronics.
Other CNC Machines
Opt Lasers Laser Heads are designed to work with any CNC machinery and connecting them to your system is pretty straightforward. To fire the laser head, you need to provide it with a 5V or 10V analog signal, or you can use a PWM signal. Opt Lasers laser heads can be mounted on robotic arms, robots, rovers, lathes and all kinds of CNC machinery that can operate a modulating signal or a 0/1 digital signal.

Cutting & Engraving Wood with CNC Lasers
Cutting and engraving wood using a CNC laser depends on the type of wood, its hardness, as well as other parameters like humidity, or texture. Materials that are easiest to cut with a laser are balsa and aviation plywood. Plywood is made of two layers of slightly harder wood, and a filler - usually balsa. Laser cutting these materials is least problematic, and the process is highly repeatable, since the wood has no knags, and has a foam-like, homogenous structure. When selecting material suitable for laser cutting or engraving, you should check its uniformity. Some variants of balsa are cheaper but may contain splinters of harder wood that are more difficult to cut with a CNC laser. Similar guidelines apply to aviation plywood.

Laser Engraving Transparent Materials with CNC Lasers
Transparency is a physical property of materials, which means that light can travel through an object without scattering (on a macroscopic scale). A transparent material is a material that appears clear and of a single color. Examples of transparent materials include plate glass and amorphous plastics (e.g. acrylics, PEI, PC, ABS, PS, etc.). Films of certain crystalline polymers, such as PET and PP, are also transparent as a result of being stretched in two directions (and thus bi-axially oriented), which aligns the polymer molecules in the film’s plane. There is consequently no refraction because of this alignment.
