The mini laser engravers are also known as the portable laser engravers, and small laser engravers, and desktop engravers. It has the characteristics of small size, being easy to carry, and more practical, and can work in a small space.

The common laser engravers are generally heavy, bulky, and not easy to move in the workshop. The operators need to move the materials or work-pieces to the workshop for laser engraving. If the work-pieces are too heavy to move, it is more convenient to use the mini laser engravers. The mini laser engraver is small in size, light in weight, and flexible in use. It is very easy to move the laser engravers to any place at any time the users want. The users only need to put this small laser engraver near to the work-pieces and turn on the power. And then they can set up parameters on the computer and begin engraving graphics or letters on materials.

· Categories and applications of the laser engravers:

The following mainly introduces the categories and applications from the aspect of the laser sources. According to the laser sources, the mini laser engravers are mostly divided into CO2 mini laser engravers and fiber mini engravers.

1. CO2 mini laser engravers:

The CO2 mini laser engraver is the marking equipment using carbon dioxide laser technology for marking non-metallic materials mostly.

The CO2 mini laser engravers can engrave a variety of non-metallic materials and some metal products. The most common materials include paper, leather, cloth, epoxy resin, acrylic materials, plastics, ceramics, bamboo, and wood.

This small laser engraver can be widely used in advertising, packaging and printing, plastics, textiles, leather, wood, and crafts industries. And the applicable industries also include electronic components, watches, glasses, and other industries.

2. Fiber mini laser engravers

The fiber laser engraver is the mini laser engraving machine for metal, and use fiber as the working medium. And it can be mainly used to engrave on the stainless steel, aluminum, carbon steel, and many metal alloy materials.

The applicable industries are generally the hardware machinery processing, tool accessories, and precision equipment industries. There are also many users in the auto parts, plastic buttons, medicine, and electrical appliances processing industries.

In addition, there is another kind of mini laser engraving machine for metal, that is, fiber handheld laser engraver. The users can hold the laser head of such a handheld laser engraver to engrave or mark on the metal parts of the large machinery.

Other types of mini laser engraver like desktop laser engraver can also be regarded as DIY laser engraver. It can be used at home, and people only connect it with their computer that the control of the desktop laser engraver happened. You can use the mini engraving machine to create wood engraving or glass engraving for personalized laser engraved gifts. The DIY laser engraver will satisfy all the requirements you want.

According to the manner of application, the small laser engraver can be divided into these types:

Desktop laser engraver: The desktop laser engraver is mini engraving machine. It has equal fundamental function with common laser cutter and smaller volume. Because of its convenience and flexibility, the desktop laser engraver has become the popular type of home laser engraver.

Portable laser engraver: If you want to engrave for enormous, unmovable objects, the portable laser engraver is your best choice. This type of engraving machine can be hold, and very easy to create high-contract pattern on the surface. Therefore, the portable laser engraver has another name Handheld Laser Engraver.

Home laser engraver: Most mini laser engraving machine can be used as home laser engraver, but the more strict requirement of home laser engraver is about the safe. You must ensure the safe of your self and families when you use home laser engraver.

No matter what kind of small laser engravers, they are easy to carry, and take up a small place. The users can also carry the mini engravers to the exhibition or market stall for laser engraving business. And they can serve as a home laser engraver, hobby laser engraver, or personal laser engraver to meet individual hobbies.

The working principle of the CO2 mini laser engraver and the fiber mini engraver is similar. The difference lies in their laser source. CO2 mini laser engraver adopts CO2 gas as the medium to generate laser. And the fiber mini laser engraving machine uses the fiber as the laser medium.

After the laser is generated, it is transmitted to irradiate on the work-piece through the optical lens. And the surface of the work-piece is under the strong heat energy of the laser. The temperature increases sharply and the materials at such a point rapidly melts or vaporizes due to the high temperature. And the laser head moves according to the working path in the computer to engrave the graphics or letters.

The users can connect the small laser engraver with the computer through the data cable. And there is the mini engraving machine software. The users can input and set the graphics for engraving into the control system of the laser engraver through software.

5. After the operation for a long time, the optical lens will be polluted by the smoke and dust.If not cleaning in time, the reflectivity and the laser outputwill be affected. The operators must check and clean the optical lens regularly. The operators can use absolute alcohol or special lens cleaning solution, and wipe it carefully with absorbent cotton.

6.During the operation process, do not move the mini engraver to avoid damaging the machine.

7. 7. Do not put anything on the mini laser engraver to avoid affecting its heat dissipation effect.After the operation, the operators need to clean the working table and the appearance of the small laser engraver.

While choosing the mini or small laser engravers, the buyers can consider three main factors. They are respectively the materials for laser processing, the power, and the laser of the machine.

· Materials for laser processing 　　

Different materials require different types of laser engravers. If the material is metal, such as stainless steel, iron, or electroplating materials, it should use fiber mini laser engraver. If it is non-metallic materials, such as cloth, wood, plastics, or epoxy resin, a CO2 mini engraver should be used.

· Power

The power of the small laser engraver is generally divided into 10W, 20W, and 30W. The greater the power, the faster the engraving speed. The power most commonly used on the market is 20W, and 10W is rarely used. After all, the speed at 10W is slower. And if the buyers have high requirements for engraving or marking speed, they can choose 30W. Of course, the price of 30W is much higher than that of 20W.

· Laser 　　

The quality and stability of the lasers are also very important. The high-quality laser can bring greater advantages to the laser engraver. First, the manufacturing technology and technical support of the high-quality laser are much better. Secondly, the good optical quality of small laser engraver can absorb the photo-electricity uniformly and automatically. The high-quality laser also has the lower environmental requirements and the higher tolerance for dust and temperature. It can be competent in a variety of environments and owns a high-quality conversion rate to save energy and cost.
