Laser Engraving Technology

Laser etching with a laser engraver machine is utilized to give items an individual outline or an individual touch. A games trophy engraved with the champ’s name, ballpoint pens engraved with the organization logo or a part set apart with serial number and group number – these are commonplace applications for laser etching. The immense preferred standpoint: With a laser machine, it is conceivable to record practically any outline on various materials. On this page, we clarify how laser etching works.

How a laser engraver works?

In laser etching, the material is so strongly warmed by the laser engraver machine bar that, contingent upon the presentation time, the shading changes and makes a complexity, or the material dissipates or consumes. The laser etching got is lasting and exceptionally impervious to scraped spot.

Laser etching with any laser engraver machine is as basic as printing. In the first place, make the chronicle format in your standard visual communication program (CorelDraw, Photoshop, AutoCAD, Illustrator, InkScape, and so on.). At that point utilize the printer driver to send the realistic to the laser machine. At the push of a catch, the chose material is laser engraved or laser cut with the settings put away. On the off chance that vital, you can design propelled settings in the provided Job Control® laser machine programming. Process composes put away in the printer driver make day by day work significantly less demanding via consequently streamlining the required designs forms, regardless of the fiber laser cutting machine that you have.

The expression “laser”

LASER is an acronym for “Light Amplification by Stimulated Emission of Radiation”. In basic terms: Light particles (photons) energized with current radiate vitality as light. This light is assembled into a shaft. Along these lines, the laser bar is framed.

Specialized structure of a laser

Any laser is comprised of three components:

·         An outer wellspring of pumping

·         The dynamic laser medium

·         The resonator.

The pump source directs the outside capacity to the laser. The dynamic laser medium is situated inside the laser. Contingent upon the sort, the laser medium may comprise of a gas blend (CO2 laser), a precious stone body (YAG laser) or glass strands (fiber laser). At the point when the vitality is bolstered to the laser medium by the pump, it transmits vitality as radiation.

The dynamic laser engraver medium is situated between two mirrors, the “resonator”. One of these mirrors is a restricted mirror. The radiation from the dynamic laser medium is increased in the resonator. In the meantime, just a specific radiation can be discharged from the resonator through the restricted mirror. This gathered radiation is laser radiation. Read more.

Properties of a laser pillar: monochromatic and intelligent

Laser radiation has three central properties:

·         Monochromatic. It implies that radiation comprises of just a single wavelength.

·         Steady with stage photons.

·         The laser waves are for all intents and purposes parallel as a result of the intelligibility

Because of these properties, the laser engraver shaft is utilized as a part of numerous regions of current preparing of materials. The force is protected for quite a while because of the lucidness and can be additionally gathered by methods for focal points. The laser bar strikes the surface of the material, is consumed and, therefore, warms the material. This warmth can totally expel or vanish the material. Along these lines, it is conceivable to record, check or cut different materials. 

Know more about a laser cutter machine

In summary we can say that laser cutting is a process that uses a beam of light of high power to melt the material of a piece allowing cutting and engraving. That is exactly what a laser cutter machine does, in summary.

The laser cutter is the abbreviation in English of Light Amplification by Stimulated Emission of Radiation, for simplicity, we can make a comparison with something that many people have tried at home or at school, which is the joke of generating fire with a magnifying glass, the concept is the same, is to amplify the energy of light to the point of heating the material in a certain region, as well as the joke of the magnifying glass, which amplifies the light of the sun at a specific point.

This beam of light is so dense that it melts and causes the material to evaporate, enabling not only the complex cutting of parts from various materials but also the recording through the regulation of energy and depth. That is the same idea applied to the fiber laser cutting machine. Despite the time of use and maintenance the lasers are still considered low maintenance equipment.

The different types of laser cutter machine

You must be wondering now, are these machines and lasers all the same? The answer is no, with the advancement of technology the trend is to increasingly arise machines with lasers, currently the market offers three main types of laser cutting and engraving check out the below:

Laser gas orco2 laser cutter

This is the type of laser most used, it is used for cutting various materials among them are acrylic, plastic, wood, glass, paper, textiles, plates and films, leather and even stone. The gas laser is a mixture of carbon dioxide with other gases such as nitrogen and helium, which is stimulated electrically, its wavelength is 10.6 micrometers, which allows the work with non-metallic materials. The co2 laser cutter is quite affordable as well. Check here.

Crystal laser or nd: yag, nd: yvo

It is also a solid-state laser, of which the most common lasers are Nd: YAG (Neodymium doped aluminum yttrium) and Nd: YVO (doped with ortho-vanadate yttrium neodymium), its wavelength is 1,064 micrometers, The same length of fiber laser, the difference is the maintenance cost, these types of lasers are more expensive and their time of hours for maintenance ranges from 8 to 15 thousand hours while the fiber laser is 25 thousand hours for the maintenance or replacement of parts.

Fiber laser cutting machine

The fiber laser cutting machine is a more complex machine, belonging to the solid state laser group, where a laser beam is generated or as it is known laser seed, amplified with special glass fibers, the wavelength is of 1,064 micrometers, its intensity is 100 times more than the co2 laser cutter, which allows much more precision in cutting, this laser due to its power is indicated for cutting metals, but also can cut other non-metallic materials.

Learn to Laser Engrave & The Advantages

There are plenty of different laser engravers on the market. If you’re looking for something that can engrave wood, plastic, marble, leather, paper, fabric, etc., then you’re looking to purchase a laser engraver. You can hook one up to your personal computer similar to that of a printer, then you’ll be etching your designs in no time.

How Laser Engraving Works

Laser engraving happens by implementing a beam of light as the etching tool. Designing with a laser is one of the fastest ways to customize any product. The most widespread laser cutting technology is that of the CO2 laser cutter or engraver. These lasers use a carbon dioxide formula that is manipulated electronically. During the laser engraving process, the surface of your chosen material is melted or vaporized by the high temperatureproduced from the beam the laser engraver makes. This process is known as ‘material removal’ and the absence of the detached substance becomes the engraving. You have the capability to choose various options through software included with your machine. This provided software helps reduce material waste, and allows quick changes to your chosen substance. Typically, laser machines require minimal maintenance and have tremendously high precision.

What Can I Laser Engrave?

When it comes to using a laser engraving machine, you typically have the capability to either use Vector or Bitmap files. Vector files consist of mathematical formulas that define lines and shapes, and are created by programs such as Adobe Illustrator, Inkscape, AutoCAD, and Corel. Bitmap files are collections of pixels and appear in Adobe Photoshop, JPGs, and digital photos. Double checking what specified file is needed for your laser engraving machine is always a smart idea, but usually vector or bitmap files are capable of being engraved. As previously mentioned, materials like some metals, woods, plastic, marble, leather, paper, and fabric are all materials that can be laser engraved.

Precautions for Laser Engraving Machines

Be careful and conscious when purchasing a laser machine. If you would like to test one out and see if its right for you, there are many options for leasing and renting laser machines. Know that laser machines operate by using a carbon dioxide laser that emits a laser that produces a wavelength of 10.6 microns. These lasers are potentially dangerous to human eyes because of the infrared radiation that they produce. This energy can easily be reflected off of materials while being cut or engraved. Also, smoke and gasses that are released while the engraver is in use are theoreticallyhazardous. Each user is responsible for their own safety while operating and reading your laser engraving machines manual is necessary.

Laser Engraving

With laser engraving being one of the most accurate processing methods in the engraving industry, it is no wonder why the success has skyrocketed in the last few decades. By producing detailed graphics with the capability to achieve a resolution of up to 1,000ppi, and the ease of use provided by laser engraving machines, it’s no wonder why laser engraving businesses are booming.

Fiber versus CO2 (carbon dioxide) laser cutting

Have you considered the differences between a fiber and a CO2 laser cutter? Deciding which machine is best for your company can be a difficult decision and this article hopes to help you differentiate between the two and decide which would be best for the specific use you intend it for.

Fiber laser cutter

A fiber laser cutter machine works by using banks of diodes (diodes act to allow an electric current to block electric current in one direction and allow it to pass in another). The light that is created is then channeled and amplified through a fiber optic cable, straightened (or collimated – “aligned”) and then focused by a lens onto the material that you intend to cut. The light creation and delivery is roughly 200% more efficient and less complex than a CO2 laser cutter machine. There are also no moving parts, which can reduce both operating and maintenance costs. They are used for many different applications – material processing (cutting, engraving) as well as telecommunications. It is also preferred to cut copper, brass and aluminum due to no fear of the machine being damaged by back reflections. It was invented in 1963 by Elias Snitzer (after roughly 2 decades of development). They have an average output power of 2.0 to 4.0 kilowatt (kW).

CO2 laser cutter

A CO2 laser cutter is a type of gas laser. This is one of the earliest gas laser to be developed, in fact. It was invented in 1964 by Kumar Patel of Bell Labs. The electricity is run through a tube filled with gas that produces light. The light is focused with the use of mirrors, which causes the nitrogen to build in intensity, become excited and release infrared light.  A concern with CO2 laser cutters are that they have moving parts that are more likely to need to be replaced and they also consume more energy, which leads to a larger environmental impact. This can lead to a more expensive end cost for this machine. They are, however, very efficient – with a ratio of output to pump power up to 20%. They are mainly used for cutting and welding. They have an average output power of 2.2 to 6.0 kilowatt (kW).  You can find co2 laser company reviews here.   More and more companies are seeing the benefits of having a co2 laser machine alongside of their CNC router.  They’re offer a lot more detailed material processing and typically not difficult to run and operate.

In Summary

If you are a DIY shop owner the most important thing to consider when choosing which laser cutter to use is the thickness of the material you intend now and in the future to cut. Fiber laser cutters cut metals more efficiently, especially materials from 1-2mm in thickness. CO2 laser cutters have a significant advantage when cutting thicker materials (above 5mm). It also produces a smoother surface.  If you want a quicker metal cut, choose fiber. If you need a thicker material cut, choose CO2.  Suffice it to say fiber laser cutters seem to be the better emerging technology.

More subcontractors (nearly 70%) prefer the newer fiber technology laser cutter, especially those that are cutting thin metal. They are a good compliment to business that already has a CO2 laser cutter at their disposal to cut the thicker materials needed.   However, if you’re only looking to mark or engrave organic material typically a 50 or 60 watt co2 laser cutter is more than enough power to get the job done.

Some of the General Points to Laser Engraving Machines

There is tons of information out there about the laser engravers. There are also many different types of engravers to choose from. There are many things that you might want to know about the engravers, especially if you are considering buying one for personal use or for your business. This is why these general points to laser engraving machines might be something that you will be interested in:

Can be used on different materials

Depending on the type of laser engraver that you are going to purchase, or the quality of the engraver, you can engrave on different materials. Normally, when you are thinking about engraving, the first thing that you might think is, that we are talking here about the engraver that is engraving on metal.

However, there are many laser engravers that are engraving on different materials. Materials like all kinds of wood, rubber, plastic, glass, metal, etc. There are other materials that you can use for engraving, depending on the type of engraver that you’re purchasing.

Materials that you can’t engrave on

Normally, you are only thinking about the materials that you can engrave on. But there are a couple of materials that you can’t engrave on, for different reasons.

For example, engraving on styrene, Lexan and PVC will not work well at all, and can even cause damage to the material or even on the laser engraver. You simply can’t engrave on them, not only because of the damage, but because of the toxic gases that can be harmful to you and all the other employees that are working and inhaling these gases. Plastic also has fumes that can be dangerous if you are not careful.

Knowing the safety measures

If you are working with laser engravers all the time, you might know about all the safety measures. However, you might not really be cautious about these safety measures anymore.

There are many reasons why there are so many safety measures that you need to take, when you are using any type of engraver. This is because of the danger that it causes. You should make sure that you are wearing the right clothing while working with the engraver and the right footwear. We don’t always know and consider these measures, because some people don’t know about the dangers that engravers can hold, especially with the larger industrial engravers.

Reading the manual carefully

Laser Engraving MachinesWe tend to throw away the manual that we get when we are purchasing new machinery. And there is no difference with laser engravers. However, there are important things that you should know about safety measures, using the engraver correctly and how to clean the engraver correctly. Read more from http://www.printweek.in/news/image-gravures-invests-direct-laser-engraver-22779

If you don’t read the manual, you might put yourself – or your workers – in jeopardy. Reading the manual carefully is essential.

These general points in laser engravers are essential to know, especially if you are going to purchase an engraver for the first time. The main thing that you should consider before you are deciding on an engraver, is the material that you want to engrave on, and the materials that aren’t recommended. This will make sure that you are buying the right laser engraver for your business or for your personal use.

Safety Glasses for Laser Engraving Machine

Who really needs to wear safety glasses when they are just using a laser engraver machine? This is the last thing that you might think about, when you are starting your working day behind a laser engraver. What serious effects can really happen with a laser machine? Here are some things that you might not know about using a laser engraver without the correct safety glasses.

 Why do you need to wear safety glasses when working with a laser engraver?

We don’t always think about the risks that there might be involved when you are using a laser engraver machine on a daily basis, especially if you don’t even consider wearing the right type of glasses.

However, there are many risks that you are exposing yourself to by using this type of machinery without protection. First of all, you might not realize it, but there are actually small pieces of scrap metal that might land in your eyes. These scrap metal might be small, but it can cause some serious trouble.  I like and recommend some of the CO2 laser safety glasses here.

Something else that can put your eyes in danger, is the laser light itself. For you, it might not look dangerous, but the sharpness of the light can cause some serious loss of eyesight, even total blindness. The light can damage your eyes without you even knowing it.

Facts about the safety glasses for the laser engraver

There are a couple of things that you should consider when purchasing safety glasses for a laser engraver. This is so that you can make sure that you are protecting your eyes as well as possible. There are some features that you should consider when purchasing your glasses to use with your laser engraving machine.

The first thing that you should know is that you should ensure that the glasses are protecting your eyes at specific wavelengths. We don’t always see these waves, but our eyes are feeling the effects of it.

The second thing that you should consider is the density of the lenses. The higher the density levels, the more protection you are going to have. For the best protection, you should look at density levels that are above 5 for laser engravers.

Shop around for your safety glasses

Laser Engraving MachineYou should make sure that you are buying your safety glasses for your laser engraver at trustworthy places, where you can know for sure that you are going to get the best possible safety glasses.
