8/8/2023 0 Comments Laser cutting machinery![]() If you are interested in getting some hands-on experience with a laser cutter, I recommend looking for a local makerspace. ![]() There are a lot of other options to get access to a laser cutter: Makerspaces In many cases the answer will be no – you don’t need to buy a laser cutter. The edges of acrylic do not change color and have a nice glossy finish after laser cutting. For example, the edges of cut wood are typical of a darker brown than the original wood. The look of the cut edges depends on the material. A laser cut is generally very precise and clean. When the laser beam goes all the way through the material of the workpiece it creates a cut. In general, there are three tasks that a laser cutter can perform: Cutting, Engraving and Marking. When the laser hits the material, a very small area is heated in an extremely short period, causing the material to melt, burn or vaporize. The shape is defined by an input file which can be a vector or raster image. Electronically controlled motors move the laser head to cut or engrave the desired shape into the material of the workpiece. Next, with the help of mirrors and lenses, the laser beam is directed to the laser head and focused on the material surface. In a CO2 laser cutter machine, the laser beam is created in a tube filled with CO2 gas. For more materials and details look here. Other types are for example fiber or crystal lasers which are mostly used for industrial applications.ĬO2 laser cutters are capable of cutting and engraving a wide range of non-metallic materials such as wood, paper, acrylic, textiles, and leather. This guide will focus on gas lasers and CO2 lasers in particular, as this type is most commonly used by hobbyists and small businesses. There are different types of laser cutters. Laser technology was developed in the 1960s. The term “ Laser” is an acronym for “Light Amplification by Stimulated Emission of Radiation”. The kind of material that a laser can cut depends on the type of laser and the specific machine’s power. The laser beam causes the material to locally burn, melt or vaporize. A laser is basically just highly focused, highly amplified light. What is a laser cutter?Ī laser cutter is a computer controlled machine that uses a laser beam to precisely cut or engrave material. You’ll also learn which material can be used and how to get access to a laser cutter. In this beginners guide, I will explain the basics of how a laser cutter works, show you some examples of things that can be made with a laser and how to create designs for laser cutting or engraving. From simple boxes to engraving detailed graphics into wood or building complex three-dimensional objects. Standards regarding tolerances are described in ISO 9013.Laser Cutters are great tools offering the possibility to create many different things. In addition, not all material thicknesses are suitable for laser cutting and, with only one torch per machine, it is a relatively expensive process. Using nitrogen entails a relatively slow cutting speed, while oxygen can burn the material in the corners of the cut. This technique also has its limitations, however. In both cases the result is an attractive narrow cut and we can work with great precision. Oxygen provides the benefit of a high cutting speed. The use of nitrogen ensures that there is less residual heat, which means that hardly any deformation occurs. To cut the products, we use nitrogen for stainless steel and oxygen for carbon steel. Other information like position numbers can also easily be provided by engraving. Engraving is useful if you wish to have setting lines and construction lines marked, for example. In addition to cutting, it is also possible to have your product engraved. This laser cutting machine is used to cut steel up to 20 mm thick and stainless steel up to 15 mm thick. One of the newest halls houses the machine that can rapidly cut products into any shape that you require to very close tolerances. Prins Staal has two laser cutting machines. ![]() A vey concentrated beam of light heats the material to melting point and the cut is blown clean by gas. Laser cutting has the greatest dimensional accuracy and best tolerances. ![]()
