Best Laser For Wood Engraving
CO2 Laser Engravers and Cutters:
It is the most common type of laser machine on the market. They used a gas mixture of carbon dioxide, nitrogen and helium to generate the laser beam. This type of machine is great for carving and cutting different types of wood, from veneer to hardwood. CO2 laser machines can make fine engravings or deep cuts, depending on the power of the machine. This is the machine of choice for most engraving and cutting applications.
Fiber Laser Engraving And Cutting Machines:
It is a newer technology in the laser engraving and cutting industry. They use an optical fiber with a doped core to generate the laser beam. This type of machine is great for engraving and cutting metal and plastic, but is not as efficient at cutting wood as a CO2 laser machine. Fiber laser machines are better suited for etching designs or images onto wood rather than cutting wood for projects.
Diode Laser Engraver And Cutter：It is a kind of semiconductor laser, its working principle is to generate laser radiation by current injection in semiconductor material. When the current passes through the semiconductor material, the recombination of electrons and holes will be excited, resulting in the emission of photons, thus forming a laser beam. It uses laser beams to process wood in a non-contact manner to achieve wood carving and cutting. Its simple and efficient processing method makes it a popular wood engraving laser equipment.
Best Wood For Laser Engraving
- Maple - One of the most popular woods for laser engraving, it has a smooth grain and consistent texture. Maple is also relatively hard, durable, and not easily dented or scratched. This hardness makes deep engraving or intricate designs challenging, but when engraved, the results are stunning.
- Cherry Wood - It has a reddish brown tone that deepens with age and exposure to sunlight. The wood is also durable, versatile and lightweight, making it a popular choice for many designers. When cared for properly, cherry wood carves very cleanly due to its tight grain and smooth surface.
- Birch - It has a light color and fine grain and is relatively soft, making it easy to carve even intricate details. The softness of the wood also means that it doesn't take much force to get a good result. Birch has a flat surface, and because of its uniformity, birch is a good choice for replicating very detailed designs, making it ideal for companies looking to incorporate logos or other branding elements into their product designs.
- Alder - Similar to birch in that it has an even and consistent surface suitable for laser engraving. It is a softer wood, which means it can be carved deeply without damaging the surface. Alder is also relatively light, which is a desirable characteristic for certain products.
- Oak - Hard and durable, which means carving deep designs in it can be challenging. But if done right, the results can be stunning. Oak also has a very distinct and unique grain pattern, which gives it a unique look and feel compared to other woods used for laser engraving.
- Walnut - Known for its darker color and rich grain pattern. Like oak, walnut is difficult to carve due to its hardness, but the results are beautiful. The design will be etched cleanly, with the dark wood contrasting with the light carved areas.
- Mahogany - Often used for laser engraving. It has an even grain pattern and a warm reddish-brown tone. Mahogany is relatively dense, which makes it more difficult to carve than other woods. However, this also means that the engraving will be more prominent and it is easy to get very deep marks.
- Bamboo - has a flat surface and an incredibly unique texture. Bamboo is also very light, which makes it popular as home decor, accessories and jewelry. Engraving can be challenging due to its fibrous consistency, but laser engraving on bamboo produces authentic results
- Plywood - is a material that consists of layers of thin wood sheets that are glued together to form a strong board. Plywood is easier to laser engrave than solid wood. This is because plywood has less grain and porosity, making them more susceptible to lasers and easier to cut and engrave.

Laser Wood Engraver Setting Parameters
1.Laser power
Laser power determines the cutting depth and speed of the laser beam on wood. In general, harder hardwoods require higher laser power. The laser power used by laser engraving machines for wood carving ranges from 30W to 120W. When engraving, you can start with low power and gradually increase it to get the best results.
2.Speed
Speed refers to the speed at which the laser head moves. Typically, the faster the speed, the less heat is generated. Therefore, when carving cork, a slightly faster speed can be used. And when carving hardwood, you need to slow down. Commonly used speeds range from 500 mm/s to 3000 mm/s.
3.Frequency
Frequency refers to the number of oscillations of the laser head. When carving wood, generally use lower frequencies for better results. A common frequency range is 5kHz to 50kHz.
4.Focal length
The focal length refers to the distance at which the laser beam is focused. When engraving wood of different thicknesses, the focal length needs to be adjusted. Generally speaking, the closer the focal length, the clearer the engraved effect.
How to Make Wood Laser Engraving Better
- Choose the right wood. Choose wood with a clear and uniform grain, which will make the laser-cut patterns clearer and less likely to burn.
- Adjust the parameters of the laser engraving machine. The parameters of the laser engraving machine include laser power, speed and frequency, etc. According to different wood types and carving requirements, different parameters need to be adjusted to obtain the best carving effect.
- Perform pretreatment. Before laser engraving, some pretreatments can be done on the wood, such as sanding, painting, etc. This results in a smoother wood surface for better engraving.
- Select the appropriate pattern. Choosing the right pattern is also very important. Complex patterns require higher power and speed, while simple patterns require lower power and speed. In addition, it is necessary to pay attention to the size and details of the pattern to ensure that the laser engraved pattern is clearly visible.
- Control the moving speed of the laser engraving machine. The moving speed of the laser engraving machine will also affect the engraving effect. If the speed is too fast, it may cause the surface of the wood to burn, which will affect the engraving effect. Therefore, it is necessary to control the moving speed of the laser engraving machine to ensure that the speed is moderate.
How long does it take to laser engraving on wood?
1. Design Complexity
Design complexity is one of the main factors affecting the time required for laser engraving. Simple designs may take seconds to complete, while complex designs may take hours. When designing, take into account the amount of detail and curves to carve, and whether multiple cuts and additions will be required to get the best results.
2. Wood Type
Different wood types have different densities and hardnesses. When performing laser engraving, the power and speed of the laser engraving machine need to be adjusted according to different wood types. Generally speaking, hardwoods require more power and speed, while softwoods require less power and speed. Therefore, it may take longer to carve hardwood.
3. The Power and Speed of The Laser Engraving Machine
The power and speed of the laser engraving machine are also important factors affecting the time required for engraving. Generally speaking, the higher the power and the faster the speed, the shorter the time required for engraving. However, it is important to note that excessive power and speed may cause the wood to burn or be damaged.
4. Pattern Size and Detail
The size and detail of the pattern will also affect the time required for laser engraving. Generally speaking, smaller patterns take longer because they require more detail and higher precision. Also, complex patterns will take longer.
Typically, the time required to laser engrave wood can range from a few seconds to hours. Here are some general estimates:
- Engraving a simple design such as a name or logo may take only a few seconds to a few minutes.
- Carving a slightly more complex pattern (such as a small artwork) may take anywhere from 10 minutes to an hour.
- Engraving a very complex pattern such as a panoramic map can take hours.
It is important to note that these estimates are for guidance only and actual time required may vary depending on factors such as design, wood type, power and speed of the laser engraver, pattern size and detail.
Precautions for Laser Engraving and Cutting Wood
1. The quality of wood is better: the quality of wood directly affects the effect after processing. Therefore, when choosing wood, choose wood with good quality, clear grain and no cracks.
2. Design before processing: Before laser engraving, design is required to determine the pattern, text, etc., as well as parameters such as processing depth and speed.
3. Pay attention to safety during processing: the laser engraving machine will generate high temperature during processing, so pay attention to prevent wood burning or harmful gas. At the same time, when operating the laser engraving machine, wear protective glasses, gloves and other safety equipment to avoid injury.
