This careful and comprehensive analysis examines not only the laser cutter equipment itself, but also the impact the new equipment will have on other existing sheet metal fabricating processes.
Fiber laser cutting has been one of the most “disruptive” technologies introduced to the metalworking market since CO2 lasers were first introduced for cutting sheet metal back in the 1980s. Fiber laser cutting technology is considered a disruptive and “revolutionary” change because it has impacted the entire status quo in sheet metal fabrication. And the opportunities are easy to realize.
Over a relatively short period of time we have seen exponential advances in Fiber laser cutting technology used for cutting flat metal sheets and plate. In just five years, Fiber lasers achieved the 4 kW cutting threshold that took CO2 lasers approximately four times as long to reach. After ten years, Fiber lasers have achieved the 10 kW to 12 kW range for which CO2 laser cutting never did. In all fairness, Fiber lasers – some exceeding 20 kW – have been used by other industries for many years in applications other than sheet metal cutting. More details!
The primary advantages of cutting flat sheet metal with Fiber laser technology are derived from its monolithic, Fiber-to-Fiber, compact solid state design configuration that is maintenance free and provides a lower cost of operation than can be achieved with comparable CO2 lasers.
Fiber laser beam characteristics also provide for much faster cutting speeds than CO2 lasers as we will explore below.
The focused beam of even a 2 kW Fiber laser demonstrates a 5X greater power density at the focal point when compared with a 4 kW CO2 laser. It also possesses a 2.5X greater absorption characteristic due to the shorter wavelength of the Fiber laser. (see Figure 1 and Figure 2).
The higher absorption of the Fiber wavelength and the higher power density created by the focused beam combine to achieve up to a five time increase in cutting speeds in materials that are less than 1/4 inch thick.
Fiber laser cutting systems can certainly cut up to one-inch thick with higher Fiber laser powers and even cut faster when utilizing nitrogen as the assist gas, but the “sweet spot” where the most significant benefits are realized is in the 5/16 inch and under range for steel when making comparisons with CO2 systems. For certain, if you are processing stainless, aluminum, brass or copper materials, Fiber laser technology is the fastest and most economical regardless of thickness.
Effectively utilizing the speed benefits from high power Fiber lasers takes careful planning and management of all processes. With a three to four time greater throughput and a cost of operation that is half of the CO2 laser, the financial gains can be game changing. The results are a lower cost per part, higher potential profit margins and shorter return on investment time. Let’s not forget the added benefit of increased machine capacity now that you are processing normal part volumes much faster, providing the opportunity to take on additional work to further increase your sales revenue and profits.
Fiber lasers can cut copper, brass and aluminum much better and more safely than CO2 because the beam is more readily absorbed and not reflected. Fiber laser operating costs are typically half of what a CO2 system can offer due to the lower electrical consumption and high electrical efficiency of Fiber lasers.
There are many aspects of operating a CO2 laser cutter that do not exist with operating a Fiber laser cutter:
Fiber optic beam paths maintain consistent nozzle beam centering.
Because the integrity of the Fiber beam remains consistent from day to day, so do the cutting parameters, requiring far less adjustments than a CO2 laser.
What becomes of all of this saved time? Higher productivity and greater machine capacity! With the Fiber laser cutter capable of five times faster cutting speeds, generating three to four times more parts per unit of time and coupled with 50% less operating costs as compared to CO2 lasers, this represents a large opportunity based on having created more machine capacity.
If you are running multiple lasers, perhaps you could consider replacing two CO2 laser cutting machines with one Fiber laser cutting machine.
The question of which technology is right for you really boils down to your operation. How well does the system fit your particular application? How much faster and how much more cost effective are your parts going to be produced? With this in mind it will be necessary to make a careful analysis of the pertinent data, including application range, operating costs, throughput, cost of ownership and, of course, the investment costs.
Whatever the final conclusion, don’t forget about the impact of this investment on your downstream processes: What effect does adding this new laser cutting system have on the flow of operations before and after the parts are cut?
Certainly knowing and preparing in advance that front-end office systems will need to keep up with the productivity of the Fiber laser helps fabricators adjust their front-end processes to keep the Fiber laser cutting, rather than waiting for jobs. Knowing that materials will need to be presented to the Fiber laser cutter in a timely manner will drive new efficiency in material handling and inventory. Knowing that increased cut part volumes need to be met with additional bending capacity will help prepare the bending area for the increased volume. For fabricators using CO2 laser cutting systems, making the move to Fiber laser technology represents a huge window of opportunity that can’t be overlooked.

Wood, newspaper, cardboard, plastic material, PMMA.Moreover,also, plastic, leather, metals, and ceramics: the actual applications of the co2 laser cutter are infinite. Perhaps because of this, among the countless different laser beam types developed over time, the CO2 laser beam has become the most broadly diffused laser technology for laser beam material processing applications. The technology of this kind of laser goes back to 1964: since then it has been successfully used in several industrial sectors.
However, regardless of the large use of the CO2 laser, there is still a great deal of confusion about how exactly the laser beam can be utilized. Do we receive many questions like Which materials can be cut by the CO2 laser? Can the CO2 laser cut hardwood? Alternatively, Can CO2 laser cut plastic? However, still What are the actual applications of the CO2 laser beam? Moreover, so forth.
There is a fairly good supply of materials sold at home supply stores, lumber yards and through commercial source channels. Manufacturers tend to procure their materials from specific providers since they’ll receive their desired width right off the truck.
Here are a couple of popular options for finding co2 laser cutter able materials:
The versatility of laser cutters is remarkable, considering they can cut, draw and etch. The laser cutter can accurately trim or etch numerous materials such as solid wood, paper, cork, plus some sorts of plastics. Laser etching can produce great results on nearly every organic material. The primary materials shops will will include wood, cardboard, lightweight aluminum, stainless steel, plastic, tile, marble, anodized aluminum, stone, and cup. Most reflective materials, such as raw aluminum, sterling silver, copper may necessitate a different wavelength and perfection beyond some co2 laser cutter machinery’s capacity. Check here.
Laser lowering materials offerartisans and manufacturers detail results using the vitality of lasers and the strength of CO2. Before you begin any cutting project, always examine your machine, take notice of the chiller temp and gauge your central heat to meet up with the wattage needs of your cutter. For an 80-watt co2 laser cutter that’ll be used in warmer climates as an example, make sure your chiller is adjusted to handle the heat load. Temps above 75 certifications F can reduce laser power significantly.
Clean your laser lens often as well. Built-up residues will cause a dramatic reduction in cutting power and reliability, with an eventual lens cracking imminent.
The list above is merely a short set of the many different materials that can be prepared by the CO2 lasers: several other materials canbe minimized with the co2 laser cutter beam. Research on the applications of the CO2 laser is still a continuing process, which experimentation plays an important role: only testing provides us with certainty about the possible claims. Because of this, we invite you to get hold of us whereby the materials you want to work is not provided in the list above. Collectively we will see you the answer that fits yourco2 laser cutter preferences!

The purchase of a laser engraver is a great decision for many businesses and is on the wish list of many amateurs. As the name implies, these complicated pieces of technology employ high-power lasers to etch designs on surfaces. Like 3D printers, laser engravers are computer controlled and perform work independently once the CAD design is available. But before buying a laser engraving machine, there are lots of things you should consider first. All these considerations are related to making the right choice when buying a recorder for your business. Here are the things you should think about before making a considerable investment in a laser engraver.
The first thing to think about when buying a laser engraver is how much maintenance costs will cost. Though you may find a laser engraver that looks like a real bargain originally, later on you could simply realize that the maintenance of that particular machine will be excessive. This is one of the reasons why it is sometimes better to invest a little more in a high-quality machine.
Another main consideration is whether you will have a hard time getting replacement parts for your new laser engraver when it breaks. And it will surely decompose ultimately, despite the machine you select and how carefully you keep it. Eventually, there will come a time when it will be necessary to replace one or more pieces. When this happens, will you have to wait weeks to get the parts you want?
A few laser engravers are very easy to maintain, which means that the maintenance staff of your company must be able to take care of the essential maintenance of the laser machine. However, some other laser engravers are difficult to perform. These more difficult machines can be extremely hard to repair as well.
In these cases, your business will have to hire a technician to perform the maintenance and repairs of the laser engraver. This costs of the company’s extra money that should be included in the purchase decision. That is why it is better to look for a laser engraving machine that is simply maintained by your maintenance staff. Click here for more information.
It is very good to buy a laser engraving machine of quality, economic and easy maintenance. But will someone on the staff have the experience to use the machine of your choice? You do not need to make a key investment in a laser engraving machine just to discover that none of your people recognize how to use it.
When it turns out that none of your employees is known with any laser engraving machine, one or more maintenance staff members will have to take courses that cover the machine you buy. This must include security procedures. Surely, it is cheaper and easier to buy a machine that is familiar to at least one person who works for you. In addition, you can make your machine vigorously produce for you much earlier, so you can begin to recover your investment.

In spite of being the oldest form of gas lasers, CO2 laser cutter are still considered one of the most valuable types of lasers. Also, it is included in the list of supposed versatile lasers since it is actually helpful in several applications and procedures. It is made of a combination of various chemical components. Apart from carbon dioxide, nitrogen and helium are present at the outlet as well. The ratio of these 3 components is 9.5: 13.5: 77. These have various roles to play in the technique. It is in nitrogen where the energy is engaged before it ignites carbon dioxide. Since CO2 produces a laser, nitrogen carries on igniting it. The role of helium is seen through the process of heat transfer.
The basic types of carbon dioxide lasers are divided into three. First, there is the axial gas flow that pumps the mixture of carbon dioxide, helium and nitrogen from one end of the tube before it exits towards the other. To ensure that the flow is maintained well, carbon dioxide is continuously pumped into the pipe. The role of helium and nitrogen in the procedure is to improve efficiency. The length of this carbon dioxide laser can be condensed with the help of folded optical methods. Also, there is a CO2 laser cutter of transverse gas flow. The gas flow for this technique is horizontally done. A third type well-known as the sealed tube is available as well. This is just same as the sealed argon and krypton lasers sealed with helium and neon. It is not filled during the process.
In addition to these types are various construction materials to take into account. The mirrors, for instance, use silicon, gold, and molybdenum, all coated. For windows, germanium and zinc selenide are used in construction. In some cases, the diamond can be used in the production of windows or mirrors. Some of the traditionally produced optical elements were made of sodium or potassium chloride. Currently, these materials are no longer used because, in spite of their low cost, production degrades rapidly, in particular when there is moisture in the atmosphere.
The cutting quality of a CO2 laser remains constant in all ranges of material thickness, while a fiber laser is a better cutter in the range of thin material, but begins to lose the quality of cutting when the thickness of the material exceeds 5 mm. Although fiber optic provides performance advantages in the range of thin material, CO2 lasers surpass them when the thickness of the metal that is cut exceeds 5 mm. While this can be true when comparing most fiber lasers to CO2, in several units the common consensus of fiber cut quality can vary. In 2kW IPG’s fiber laser units have been shown to reach a cutting quality equal to or better than the CO2 laser up to 12 mm in mild steel. With this thickness, the laser cut at the similar speed as CO2 and the power consumption per cut was even lower using fiber technology. Check this site.
In general, CO2 laser cutters are used in cutting, engraving, and heat treating, as well as welding. In addition, they are significant in the production of cardboard, fabric, paper, plastics, wood, and ceramics. They can also be used in medical fields especially in the world of dermatology. Dermabrasion, laser surgery, and skin rejuvenation are some of the examples in this application.

If you want to stand out with customers or clients then you should understand the benefits of laser cutting.
Within the past few years, businesses have launched which specialize in custom laser cutting operations. These specialists work with everything from metal to paper. Cutting paper with a laser is particular exciting because it allows very complex designs to be replicated exactly. Paper works as an excellent substrate and can be cutting with near perfect edges.
Until the past few years paper products have been cut by a hand with scissors or by a blade-based machine. Both of these methods have severe limitations. With hand cutting, the cut is only as good as the worker and machines quickly dull or lose alignment. Both of these methods often produce a less than perfect result. Unfortunately, a few decades ago before the commercialization of the laser these were the only options.
Another benefit is the relative speed of most commercial systems. Hand cutting detailed patterns can take hours or even days. Also, with hand cutting, mistakes are frequent and precision is often fair at best. Powerful lasers have the ability to cut the same pattern in often a few seconds. Furthermore their ability to replicate the same design is unmatched with conventional methods. The newest system can cut with precise down to a fraction of a millimeter with a perfect edge. This precision also enables layering of patterns or even mass production of paper products.
Here are a few list of the laser cutting designs:
Clear Acrylic – 3.0 mm. Top Quality: Engraves Beautifully. Why is clear acrylic the #1 choice of makers in 2016? Because of what it shows during the reaction to the laser machine. The surface and the area of the said thermoplastic engraves a super nice and artistic frosty finish product that catches the light so wonderfully and also the edges will melt smoothly instead of burning such as the wooden materials. Clear acrylic is popular for co2 laser machines as you can see here.
Amber Bamboo – 2.7 mm. Top Quality: Natural Honey Tone. Bamboo is said to be the super versatile. Makers will use it create designs for jewelry, electronics enclosures, tableware, conference badges, book covers, signage and also displays for sale purposes.
Birch Veneer – 5.2 mm. Top Quality: Thicker yet Economical. When you need thicker wood for your laser cutting projects, this is the top choice. Like its thinner companion, this birch is commonly used in making product for housings, drones, prototyping, clocks, furniture and also signage.
Black Acrylic – 3.0 mm. Top Quality: Classic Black. Black acrylic is a classic favorite. Why? Because engraving looks so good on this material. This frosty white kind of engraving contrasts creates a beautiful black design.

Typical custom laser cutting projects begins with a designer creating a digital image of a pattern. This design should be reviewed carefully to ensure that all regions of the pattern are connected and well supported so it will be structurally strong. Modern co2 laser cutter system can cut thick paper products and even textiles which give designers a wide range of substrates to choose.
For more detailed patterns thicker substrates are often recommended to prevent structural instability. Often, trial or sample cutting on a variety of substrates to a good way to judge if the laser cut design is strong enough to fulfill its purpose. To avoid these downfalls often choosing a manufacture’s professional pre-made design can ensure it is both pleasing and functionally strong.

Design using code. Paul Krix who is a designer, creates intricate designs of his work that were pattern-based in nature which were manipulated through software in order to generate the final designs. Many designers who use laser machines are inspired by forms or patters found in nature, but there are few articulate organic influences from a scientific ways. Paul Krix creates uniquely and artistically an individual personal laser cut for jewelry which was aesthetically being informed using programming based on algorithms that he discovered several years ago. Later, Paul came across to the field of research about algorithms copying the chemical procedures and process of leaf formations as well as deciding to use it as his basis for the modelling system. visit her latest blog posted at http://awesomesaucebookclub.com/how-to-laser-cut-the-basics-of-cutting-with-a-laser-system/
The incredible, amazing Folding Ukulele which comes from the ‘maker of anything’ called Brian Chan. The ukulele was designed by Brian Chan who didn’t want a traditional ukulele, and so went about changing the basic shape to make it foldable for ease of portability. Soprano and the supermini sizes of this kind are available anytime on Ponoko, either fully finished or in kit form. With the design being drafted already, Brian was able to get in touch with Josh, a Community Support trusted Manager, to make a prototype of his project through laser-cutting. As you can see, the design is pretty complex, consisting of multiple flat pieces that need to fit together perfectly to create not just a 3D object. visit their official website for more details.
Generative laser cut puzzle. This unusually intricate laser cutter design of a wooden puzzle through the Nervous System which was unique in a sense. It was then designed using the so-called generative technique in the form of processing—that is why every single piece is made uniquely and each puzzle was made in this manner would be somehow amazing and unique. If 2 or 10 puzzles were being made, no 2 pieces in every puzzle would be the same.
The said puzzle happens to be just an experiment for an upcoming potential product. I cannot wait to see what image and form they will include in it. If you’re looking for a laser cutter machine check out www.bosslaser.com. You can find reviews of Boss Laser in Google by just typing their company name.
Robotic claw business card. Another top headline contender. My old favorite laser business card project was, of course, Meat Cards, thus robot claws will definitely outclass for a contact information jerky. The design continues to evolve, so be sure you check out the latest updates about instructions where you may able to find all of the needed information in order to build unique robotic claw for business card solely.
Ornamental laser cutting. This is a roundup post of several breathtaking ornamental forms of laser cut arts and designs covered by A laser cutter. My favorite of all is the topographic model cut in a form of a chunk of Mars. It is the sort of this thing which you could see in photographic or data form coming from the NASA; however, only digital fabrication can possibly make it more tangible.
