The Use of Laser Cutting in Sheet Metal Prototyping

Although there are several ways in which sheet metal can be shaped and cut, few are as accurate, reliable and inexpensive as laser cutting. The technology involved in laser cutting machine is so useful that a continuation, as well as improvement of their future capabilities, is inevitable.

Categories of Laser Cutting Tools

Laser cut is a flexible tool whose use can be applied in a wide spectrum of materials like stone, glass, plastic, wood, and sheet metal.

  1. CO2 laser

A CO2 laser cutter is a popular type of tool that is valued because it is easy to control and highly precise. A beam made of concentrated CO2 gas is activated by electricity to power the cut.

  1. Fiber Laser

A fiber laser uses glass fibers to enhance the potential of a seed laser. The result is a laser that is more powerful as well as more accurate than the CO2 laser cutter. A fiber laser is usually used for metals due to its focused and intense beam.

  1. Crystal Laser

A crystal laser is similar to a fiber laser, except that it uses pump diodes and crystals to generate the power of its beam. A crystal laser has a performance and application potential comparable to a fiber laser.

Benefits of Using Laser Cutting with Sheet Metal

There are numerous reasons why the use of laser cutting machine is the preferred method when developing a prototype sheet metal.

  • More Intricate

As a laser has an average size of just a few micrometers, it allows the accuracy to create and cut sheet metal prototypes that would not be possible if other methods were used. On the other hand, this results in an almost unlimited range of possibilities.

  • Finished Edge

The use of a physical technique like a blade, to cut metal sheets produces imperfections, such as roughness and burrs, along with the edge. For a lot of designs, these would need to be buffed out or otherwise eliminated which may increase the time it takes for the end user to get their product. The use of a laser eliminates this problem.

  • Scalability

The tools allow companies to cut as many or as few sheet metal prototypes as their customers want. In general, these lasers do not have to be adjusted or reconditioned to fit the design of a certain part. When adjustments are unavoidable, they are easier to perform when you use a laser cutter.

Laser Cutting and the Future

As of right now, CO2 laser cutters are still the industry standard, although fiber lasers are being rapidly adopted. Even though it is quite new, it is projected that fiber laser technology will become standard in the next 10 to 12 years. Several companies will continue to use their CO2 laser cutter along with their fiber lasers, providing them with more design options they can provide their customers. In addition, it could be combined with 3D printing to create accurate and reliable products for customers.…

Engraving Machines – A Lot Less Expensive Today

Engraving Machines

For most people, when we talk about laser cutting, we soon think of something expensive and inaccessible to small businesses. But it turns out that a new generation of low-cost machines are going strong in the market. How about we take a look at this technology? It is really affordable to find laser cutter machine that are good and fit for businesses of all sorts and sizes. If you need new technology and some extra cash at the end of the month then this definitely is for you.

What is laser cutting?

The laser cut is nothing more than a CNC system coupled to a laser emitter. As the emitter has a certain size it is not directly connected to the head of the CNC. In fact, in the head is only a mirror that captures the laser beam and concentrates the ray. This is available in all sorts of laser cutter machine.

A 40 w laser is capable of cutting multiple sheets of paper at the same time and up to other materials such as MDF (about 10 mm, acrylic or thin metal parts.

In heavy industry has laser of all that is power, cutting very thick materials. But let’s focus on those small machines, 40 w or more, that are very accessible to small business owners looking for an opportunity to get an affordable laser cutter.

Laser cutting operation

As the ancients would say, a picture is worth a thousand words! visit us now!

That’s why I preferred to show a machine like that by cutting pieces of paper. The machine used here is unimportant. The important thing here is to know that these machines take the vector files of Corel Draw and transform it into a way for the laser to make the cut. With small adjustments you can regulate the power of the laser to just mark the material or to make the cut by the laser cutter.

Other uses for the laser

Engraving MachinesBut having a laser just to cut paper can be a waste of time and money. Such a machine allows gains in several areas where the chart is already fit, but other people are not. And what else can we do with these machines?

One of the market that caught my attention for these machines was the craft. It uses laser to make cutouts in MDF, paint stencils (molds), wood engraving, plastic (care that gases can be toxic and need a good exhaust), metal or other materials and more.

In the area of ​​signage and marquee we can use these machines to make acrylic cut, making letters and figures complex, many of them difficult to be made with other types of router. It is good to remember that the machine regulates the intensity of the laser, allowing both cutting Such as roughing or even just burning or heating the material. Therefore investing in a laser cutter is indeed a good idea, even for the small business across the world. Are you ready to invest little cash and get tons in return?  I like  Epilog Laser cutters but if you want to buy direct from China and go cheap be careful!  I’ve read some bad forum reports on China made laser cutters.  Here’s a Bodor review for example.  Its your choice and the risk to buy cheap usually doesnt pay off.…
