Then the so-called laser engraving is the use of laser technology for engraving. The principle is to use laser heat to burn or chemically change the engraved surface to produce engraved marks.
The advantage of Sculpfun laser engraving machine over hand-held tools is that the engraved text and pattern can be controlled, the size can also be controlled, and the engraved pattern is relatively fine. The disadvantage is that it is not three-dimensional like manual solid carving. Therefore, laser engraving machines are mainly used for shallow marking.
The concept is clear, let's talk about the structure of the Sculpfun S10 laser engraving machine. The laser engraver realizes the engraving function,
It mainly requires software to control the mechanical transmission and several main components of the laser light source. Among them, the software is used as a human-computer interaction page to perform graphics and text editing, parameter adjustment, start-stop and other operations.
The traditional engraving machine is driven by a stepping motor or a servo motor through the mechanical transmission part. Of course, due to the nature of lasers, many modern machines employ galvo mirror systems that control the position of the laser by controlling the slight movement of the lens.
The laser light source is the core component of laser engraving. The characteristics of the light source determine the material effect of the laser machine to achieve engraving. The amount of energy has a great influence on the depth and speed of engraving.
Classification of laser engraving machine light source
At present, the common light sources of laser engravers on the market mainly include CO2 light sources, fiber light sources, purple light sources, green light sources, and diode light sources. The laser wavelength is different, and the engraving efficiency is also very different
●CO2 laser engraver is mainly suitable for the engraving of wood, leather, plastic and other non-metallic materials
● Optical fiber light source, the main engraving material is metal or paint material, with high density. Wood is generally not easy to carve unless it is very dense and hard.
●Purple light source is a relatively high-end light source, the engraving is very fine, and the engraving range is very wide
●Green light source, we may see a lot of 3D images in the middle of acrylic, usually engraved with green light source. Can engrave transparent glass and other materials
●Diode light source, originally a stage lighting light source, has achieved a gorgeous turn in the laser engraving industry. Its carving principle is somewhat similar to lighting a cigarette in the sunlight of a magnifying glass.
Selection criteria for laser engraving machines
I believe that many friends who want to buy a laser engraving machine are most concerned about this issue. Everyone definitely wants to choose a practical and economical laser engraver machine. So before choosing, you can first understand the advantages and disadvantages of various laser engravers
●CO2 laser engraving machine: The advantages of engraving materials are a wide range of wood, leather, plastic, rubber, etc., high power, fast engraving speed and high precision. Disadvantages The machine is bulky, generally weighing 40-50 kg. Moving is inconvenient and the price is average. Suitable for factory
●Fiber engraving laser machine, advantages: high engraving precision, fast speed, suitable for batch operations in factories, and can be connected to factory automation production lines. Disadvantages The machine is generally more expensive, the volume is relatively large, and the weight is more than 30 kilograms
●Purple laser engraver, advantages: wide range of engraving materials, both metal and non-metal can be engraved. One machine can be used for many purposes. The disadvantage is that the price is expensive, because of the characteristics of the purple light source, the machine is also relatively heavy. Suitable for high-end manufacturing
●Green laser engraving machine, the advantage is that it can realize three-dimensional engraving and three-dimensional positioning engraving. The disadvantage is that it is bulky and expensive
● Diode laser engraving machine, low price, small size, easy to move. Disadvantage: The engraving speed is slow and cannot engrave pure metal. Due to the speed limitation, it is generally more suitable for personal DIY home use, or small-scale customization of small and medium-sized enterprises, such as: Sculpfun S9. In addition, the power of Sculpfun S30 Pro Max laser engraving machine is up to 20W, which is much more powerful than the same type of desktop laser engraver.
