Advantages and disadvantages
The advantages of a laser engraver include:
- accuracy of drawing;
- ability to work with different types of materials;
- simple controls;
- waste-free production.
The main advantage of the device is automation. Thanks to software control, the likelihood of error is minimized. However, they are not excluded and you need to learn how to use an engraver.
With a sufficient level of skill, you can cut out complex designs
However, the equipment also has disadvantages. During the cutting and engraving process, it is impossible to adjust the depth of the design. Therefore, the surface will be non-uniform and this is not always good. In addition, not all materials tolerate laser treatment well—they become deformed under the influence of high temperatures.
Another drawback of the engraver is its low productivity. Even with a powerful model, it can be difficult to produce a large batch of products. You will need to take breaks.
What you should pay attention to when choosing equipment
When choosing a machine, you need to consider a number of factors:
- Dimensions of the structure, desktop.
- Engine power.
- Model of laser equipment. Imported samples are more expensive.
- Availability of software.
- Machine performance. Its ability to be used for a long time without interruption.
- Type of cooling system.
- Quality of the focusing lens system.
- Laser beam power.
- Availability of additional functions. For example, a separate system that removes excess production from the work area.
It is important to understand that CNC machines require knowledge in programming, troubleshooting, and creating algorithms. Beginners are advised to buy Chinese models, which are cheap. It’s convenient to hone your skills on them; it’s not as bad to ruin them as professional models.
Kinds
Before choosing a laser engraver, you need to decide on its type. This will help save money. In addition, with the right choice, you can find equipment that will be ideal for performing the assigned tasks.
Important! It is not necessary to consider only European or American brands. Among the Chinese there are also many worthy brands.
By source type
There are two varieties:
- Electrical. Just plug the device into a power outlet and it will start working. However, it can be difficult to move it to another location due to the length of the cable.
- Rechargeable. Portable models that are easy to move. However, they work for a limited time, after which the device will have to be charged.
There are also two types of engravers:
- Gas. Inside the device there is a tube containing a gaseous substance. Suitable for applying designs to leather, wood, plastic, glass, etc. Does not work with metals.
- Solid state. Solids are used as the active medium. Works with most materials. They are more expensive than gas ones, but are more suitable for industrial work.
By working surface area
Desktop engravers are suitable for home use. They do not take up much space and allow you to work with small batches of materials. However, they do not always provide a good view of the work surface.
Desktop engraver fits easily on a regular desk
Medium-sized devices offer great capabilities. They can handle a good amount of work, but they will need space. For example, in a garage or separate room.
Industrial machines with an area of 1.5 m are suitable for large-scale production. Special workshops are used for their installation. In addition, working behind them will require special qualifications.
By power
Choosing an engraver for your home is not such an easy task. The higher its power, the better the performance, but at the same time energy consumption increases. At the same time, there is one more nuance: the thicker the material, the stronger the device should be.
Therefore, before choosing a laser engraver, you should decide on the prospects. So, to work with materials up to 5 mm thick, a 15-20 W model is sufficient. Only the speed of this model is low and the work area is small. If you increase the power, the engraver can handle a 10 mm sheet.
A device of 80-100 W is enough to work with metal, plywood and other materials. This will give you good speed and working area. There are engravers with a power of 100-200 W - this is typical for industrial work.
For reference! For powerful devices, sometimes a conventional 220 V outlet is not enough. When choosing, you must pay attention to this.
What factors are taken into account when choosing an emitter for a machine?
The Wattsan company equips its laser metal cutters with products that are most in demand on the market, the production of which is established by manufacturers: IPG, MAX Photonics, Raycus.
The power range of the mentioned emitters is quite wide, 0.35-25.0 kW. The service life of products declared by the manufacturer exceeds 5 years. The products are distinguished by significant efficiency and reliability, and efficiency (the ratio of energy consumed and its resulting value) can reach 30, and for some models, 50%.
For machines in the Wattsan line, there is a direct relationship between the thickness of the frame and the power of the emitters installed on them:
- Equipment with a frame whose thickness does not exceed (8.0-10.0) mm most often receives emitters whose power does not exceed 2 kW;
- Equipment with more powerful (10.0-12.0) mm frames is equipped with emitters, the power of which is set in the range (1.5-6.0) kW;
- The most durable frames, the thickness of which is (12.0-16.0) mm, are obtained by emitters with N≥4kW.
Wattsan machines are designed to operate at the highest available speeds with emitters up to 6 kW (inclusive). Even when the workpiece is thin sheet metal.
The relationship between equipment parameters such as the body and maximum permitted speeds is discussed in a special article and discussed in detail in this video.
Practice shows that the vast majority of workpiece materials of varying thickness can be efficiently processed with a fiber laser of similar power. Therefore, it is not economically feasible to purchase a “cooler” machine. The largest percentage of purchased machines have emitters with a power of one or two kilowatts.
Why do you need a laser engraver?
You can find a reliable device, but first you need to decide on the scope of application. For example, making drawings, decorative finishing of packaging, making souvenirs and much more.
Powerful laser engravers are indispensable in funeral agencies. Using the program, the wizard determines the text, drawing, and equipment performs the task. Another option is to make tombstones.
Important! The more multifunctional the device, the more expensive it is. But there are more prospects with him.
The choice of engraver must be made taking into account the complexity of the work. To create complex designs such as barcodes or stamps, fine tuning is important. Engraving is mainly in demand in the field of advertising and the manufacture of souvenirs.
Scope of application of engravers
In terms of their functionality, engravers are used wherever it is necessary to finely apply patterns, barcodes, stamps, drawings or inscriptions on various surfaces, including complex shaped ones.
This:
- applying artistic patterns to wooden products;
- production of packaging, incl. decorative;
- outdoor advertising;
- production of souvenir products from metal, wood, glass, plastic, stone;
- drawing patterns on leather materials, in the textile industry - cutting complex materials.
The engraving machine is also successfully used in funeral services for engraving inscriptions on monuments.
How to choose
It is not necessary to buy the most expensive engraver. There are decent cheap models. When choosing, several criteria are taken into account - purpose of application, materials, key characteristics and performance. This will help you buy a truly useful device.
Purpose of application
Laser engravers are needed in the following cases:
- production of souvenirs;
- jewelry making;
- production of awards;
- creation of advertising products;
- light industry.
Materials for processing
The more options the better. If you plan to work with a limited amount of materials, then you can choose a simple model. For example, which works with acrylic, MDF, plywood. Metal and leather will require powerful engravers.
Key Features
When choosing, you need to pay attention to:
- laser beam accuracy;
- size of the working area;
- software.
Consider the presence of a cooling system. It prevents equipment overheating and increases operating speed.

Key equipment characteristics
When the choice of equipment for laser engraving has been made according to the above criteria, we move on to the main characteristics of the machine. These characteristics are crucial for subsequent successful operation, and focusing on them can save a lot of money when purchasing.
5.1. Laser power
The amount of power is directly proportional to the overall productivity of the engraver, including processing speed. However, there are some peculiarities. For example, with high power, you can process harder materials, just at a slower speed. The downside of this option is high power consumption
5.2. Machine cooling system
There are options: whether the laser generator is equipped with such a system or not. The duration of continuous operation of the engraver depends on the cooling system. In addition, the cost of the machine directly depends on this parameter. When choosing a cooling system, we pay attention to the manufacturer and the technologies used. Branded products last longer than cheap Chinese counterparts, although, accordingly, they are more expensive.
5.3. Optional – electric drive and table lighting
Despite its simplicity, the electric drive of the table greatly facilitates laser control. Since the auto-focusing function of the beam is activated, which improves the engraving accuracy. The electric drive is used mainly in industrial or professional machines that work with large volumes of materials, and illumination of the work area makes it easier to control operations.
5.4. Software interface
Please note the variety of functions that can be reprogrammed. We will also make sure that the interface is easy to learn and its functions are intuitive.
If you plan to use a laser engraver on an industrial scale, you should think in advance about such a thing as the cost of a standard hour of operation of the machine.
Features and advantages of Chinese products
Among Asian engravers you can find models of different sizes. They have an average cost, but some people have distrust of such products. Modern Chinese production has high quality standards.
Important! When choosing an engraver, it is important to remember that the cheapest models do not differ in quality and performance.
The advantages of Chinese devices include:
- thoughtful and functional software;
- the plastic case is no worse than the metal one, but costs less;
- wide range of possibilities.
The peculiarity of engravers from China is the variety of forms. You can find a tabletop or manual version, also semi-industrial. Some models can accurately reproduce a seal or stamp - this function is needed for making corporate gifts.
You can apply text of any level of complexity to the material
When choosing a laser engraver, it is important to study the features of different types of devices. Only after this can you begin to search for specific models. This will save time and money.
Types of engravers and differences
The next step is to select a device based on the type of laser beam source. There are 3 types of engraving machines based on this feature:
- solid state;
- gas;
- hybrid.
In comparison with traditional methods of electrochemical and mechanical engraving, laser engravers show better characteristics in such parameters as visual appeal, pattern durability, and the ability to mark a product in series or in a constant technological cycle.
Engravers of the first type (including their varieties - fiber lasers) are designed to work mainly on hard surfaces: metal, plastic. They are distinguished by the highest quality and precision of patterns. However, these engravers do not mark wood, cardboard, or glass.
Gas engravers operating on CO² have proven themselves excellent on plastic, paper, ceramics, plexiglass and glass, rubber, and wood. However, metal as a material is not available for marking with this type of engraver. There are also restrictions on the size of working areas and the types of images displayed. For example, the inaccessibility of vector graphics images.
Hybrid devices combine CO² and fiber lasers, providing the advantages of both in “one bottle”, but losing in narrow specialization.
