Heartier fabrics such as denim, canvas and leather can withstand higher power settings during engraving. Clear acrylic parts get edges that is completely transparent and they rarely required more machining. You apply all of the application tape to the entire surface of the wood to be cut. When the laser comes into contact with the cutting bed as it slices through the material, debris is deposited onto the reverse face. I’m assuming you’ve clicked through to this article because the burn marks are undesirable (and you’re not making an attempt at the art of pyrography! This usually has more to do with the glue binders embedded in the material rather than any inherent property or grain of the wood itself. Why doesn't my laser burn things? As the application continues to be used for many industrial purposes, it’s also growing in popularity … they are suitable for cutting gems, jade, brick, marble, glass, etc. Also available is a laser cutter user guide.. If you’re cutting wood that has an uneven grain to it or a high moisture content (birch plywood would be an example), you will want to rely on higher tack masking tape, for the low-tack variety may not offer sufficient protection since it will peel off too easily. Benchtop Tool System. This is helpful for figuring out where the laser will cut before you run your job on your material. When your artwork is very dense or we are cutting a less rigid material such as paper or fabric we need to use the honeycomb bed to keep it evenly flat as the pieces are cut. This is helpful for figuring out where the laser will cut before you run your job on your material. Laser cutting is noncontact, which can deliver a finer finish without cracks. I hope this helped you and you don’t end up with too frustrating a problem or too high of expectations with laser cut wood. Laser cutting acrylic is developing a clear smoke with distinct sweet smell. As I already stated earlier, Fumes and/or debris residue is nearly always created when the laser cuts the wood. going again and seeing if anyone has any ideas here. If you are like me, the cooked and yellowed edge isn’t the most attractive finish for most applications. Close. Now, these burn marks don’t occur on every material you cut; laser cutters will either incinerate, vaporize, or melt certain materials depending on their composition. What exactly causes these burn marks to occur so prominently when cutting some materials like wood and not others, How to take preventative measures beforehand to ensure such unseemly burn marks don’t ruin future projects, Some quick tips to remove light charring on pieces that have already been cut, If you tried some of the other tactics and you only have a minor amount of burn marks and stains on the engraving edges, try.

Please contact your equipment’s manufacture to see if your laser is able to cut polycarbonate and for recommendations on the process. Material PreparationBy managing these variables, we are able to ensure perfect, reliable and repeatable laser cuts of our acrylic material. For burning, you need to turn the adjustment lens (black plastic piece) until the size of the laser dot is the smallest at a particular distance. All the markings will transfer onto the protective tape and not the material. The laser I use has the option to turn on a laser pointer that projects a red dot where the cutting/engraving laser will fire. Laser Material Processing uses laser energy to modify the shape or appearance of a material. To reduce burnt edges, there’s a few things you can play around with on your laser machine to see if it produces any positive results for you: An ounce of prevention is superior to a pound of cure. What makes a material not suitable for laser engraving and cutting? Fortunately, there’s a simple, low tech solution for this problem. If you do not mind the discoloration and fumes, you can laser cut very thin sheets of less than 1mm using a 10.6-micron CO2 laser. Polycarbonate is often found as flat, sheet material. Because of such high temperatures, these fumes scorch the surface right around where a laser beam cuts material. You will then need to peel off the backing to reveal the clean material surface. But here’s a couple of other things you can try if those seem to not be working as well: It turns out that certain kinds of wood are more susceptible to charring than others. As I explained in this video on using laser marking machines for other applications, there are some basic guidelines for laser cutting: Consider the type of material you want to cut, either organic (wood, packaging, etc.) When cutting acrylic on a metal cutting bed, the laser energy may hit the metal cutting bed and bounce back into the material causing divots or … Because of the glue embedded in materials ike plywood and MDF, these materials will typically leave more burn marks than pure wood. It … Then run the file and watch where the red dot goes. The first step in avoiding burning fabric with a laser engraving/cutting machine is to understand which fabrics can withstand the process and at what temperatures. This is a neat demonstration for showing the potential use as a directed beam weapon! Browse the materials gallery to see more on how certain classes of materials react to the laser and how we go about minimizing them. ABS Emits cyanide gas and tends to melt ABS does not cut well in a laser cutter. It has a printing/ engraving area of 214 x 186 mm (8.4 x 7.3 inches). Sometimes burn marks will occur where the laser comes in contact with the cutting bed as it slices through on the reverse side of the material. Residues from repeat cutting can also transfer back onto the reverse of a material from lamella but unlike honeycomb, the marks are a lot less. You need to analyze and compare data of different configurations of lasers (power, core diameter) and cutting head (focusing and expanding beam ratio, focusing method) and data such as air pressure, focal length, and moving speed to obtain a set of systematic cutting data through experiments. The Harmful Side Effects of Laser Cutting. Smaller Kerf widths are also maintained with compressed air by minimizing the heat of the laser at point of contact with the material surface. Other materials like acrylic will usually appear slightly melted or glossy, but barely noticeable where the laser beam has cut. Laser Process Setup 1. Also called "burning stabilized laser gas cutting", "flame cutting". The tips I’ve already mentioned are probably the most common. Very thin polycarbonate can be cut, but tends to discolor badly. 2. This is the frequency of light the laser cutter uses to cut materials, so it is very ineffective at cutting polycarbonate. Adjust the saw speed so the blade is moving at approximately 12,000 strokes per minute. from Achievement Matters PRO . C02 laser cutting is essentially finely burning through a material and engraving is delicately burning into it. Laser cutting is a poor choice for a thick polycarbonate panel of more than 1mm thick. If you’d like to learn more about ablative laser cutting, check out this article on Micron-Scale Manufacturing.. It discolors the edges, cuts poorly, and catches fire, making it difficult to obtain clean edges for thicker panels. That is because outside of the design, it has some intuitive features for those who want to start laser engraving. Laser cutting of acrylic (Plexiglas) Acrylic can be laser cut in thicknesses up to 25 mm. The aluminium honeycomb cells support the material whilst allowing heat and debris to dissipate from beneath. When you stop to think about what is happening, a CO2 laser is basically just finely burning through some material like wood. We usually need to vector order your artwork (select the order in which pieces are cut) to achieve this. The high-precision laser vaporizes a cut line through the acrylic, leaving a 90-degree high-quality cut-edge finish. So now that we’ve briefly looked at some of the reasons why laser cutter burn marks happen in the first place, let’s look at a few ways that one can minimize some of these ugly marks that might ruin your project, or otherwise make it turn out in a way that’s suboptimal. Then run the file and watch where the red dot goes. Many proprietary grades of polycarbonate are manufactured under trade names such as Lexan™, Makrolon ™, Anjalon ™, Durolon ™, Lupilon ™, Lupoy ™, and Panlite ™.Laser cutting polycarbonate is best done using a 10.6 micron CO 2 laser, which produces a smooth but often discolored edge. Laser cutting machines are classified by the American National Standards Institute, with most being designated as a Class 1 laser. © 2015 CutLaserCut Ltd. All Rights reserved.Company registration no: 9850549 Unfortunately the more contact the reverse of the material has with the laser bed the higher the risk of marks on the reverse. No burning occurs with other materials, like metals or plastics. Therefore one should naturally expect there to be at least some browning or amber color along the edges of a cut project. Although some degree of this is to be expected, it quickly turns problematic when there is significant charring and soot that is no longer aesthetically pleasing (typically when the burn marks are too dark or leave “laser tails” on select portions of a cut). Laser will incinerate most flammable materials 3 to 5 meters from beam exit aperture -- without any optics! 4. Given its dominance in the sheet metal cutting industry, this article focuses on laser fusion cutting. In fact, the best surface to use when printing with Polycarbonate is Polycarbonate.

I've found the best way to eliminate burning on any kind of acrylic/plastic/delrin is to make a jig with an 1/8" piece of scrap acrylic, laser small dots where you won't be lasering through your finished piece, and then glue long 6"+ nails (head down) in those spots (5 minute epoxy works well to support the nail). These machines can cut or engrave steel, titanium, stainless steel, wood, plastic and much more. This is a similar process to using masking tape. Polycarbonate is a poor choice for laser cutting. Laser engraving is similar, but instead of using the laser beam to cut through the material sheet, it engraves the material surface. Accurate focusing and the right choice of the optics are crucial for this process. The first step in avoiding burning fabric with a laser engraving/cutting machine is to understand which fabrics can withstand the process and at what temperatures. Large format protective backing is a sticky back masking tape that can be applied to a material surface prior to any cutting or engraving is carried out. Leather is a premium material that's been used for centuries but also exists in modern fabrication processes. If you have other settings you’d like to suggest, please send an email to design_help@ncsu.edu with the details. On plastic for instance the edges appear melted / slightly glossy. Make sure to smooth out all bubbles beforehand, otherwise that could lead to results that are even worse. When laser cutting your material needs to be supported efficiently from underneath to allow it to remain flat at all times but also allow heat from the laser to escape from underneath. First, it’s important to note that what’s typically causing the burn marks to be left in the first place is not the high-powered beam hitting the surface of the wood itself, but rather the fumes and debris emitted while the cutting process ensues. Laser machines can cut wood, paper, plastic, fabric, foam, and much more with such high precision and speed, giving lasers a clear advantage over other types of cutting technologies. In this process both Laser Kiss cutting and Thru cutting of difficult polycarbonate material is achieved without a pre-mask. In fact, some laser cutters are not able to cut it because it ruins the lens and requires frequent stopping and cleaning. If the materials listed above are laser engraved or laser cut, dusts or gases may be produced that endanger the laser user or the functionality of the laser machine. So ideally, you’ll want as little contact between your project and the cutting bed as possible. Apparently this seems to work well because it prevents the edges of the engraving from getting stained. To complement this calibration, air nozzle settings of 26 – 30 pounds per square inch (psi) are also optimal, as well as a cutting speed of about 25 inches per minute. Table Setup 2. We love all things crafty. Determining the laser engraving parameters. Many proprietary grades of polycarbonate are manufactured under trade names such as Lexan™, Makrolon ™, Anjalon ™, Durolon ™, Lupilon ™, Lupoy ™, and Panlite ™.Laser cutting polycarbonate is best done using a 10.6 micron CO 2 laser, which produces a smooth but often discolored edge. Fumes and debris are emitted when cutting / engraving. The visor is cut from 0.5mm polycarbonate and the retaining/adjustment straps are made from 0.75mm polypropylene. The ideal scenario is for us to completely float the material so no heat builds up underneath. First, it’s important to note that what’s typically causing the burn marks to be left in the first place is not the high-powered beam hitting the surface of the wood itself, but rather the fumes and debris emitted while the cutting process ensues. All our material settings are optimised to maintain the cleanest cutting and engraving conditions and to keep these burn and heat marks to a minimum. It comes in rolls up to 1220mm wide. Leather is a premium material that's been used for centuries but also exists in modern fabrication processes. Heartier fabrics such as denim, canvas and leather can withstand higher power settings during engraving. Reactive cutting is like oxygen torch cutting but with a laser beam as the ignition source. Again, allow the blade to perform the cutting; do not force the saw through the material. Exhaust 4. Laser cutting wood without burning it? By directing a constant stream of compressed air at the point where the laser meets the material, flaming, scorching and charring is reduced on materials such as wood, acrylic and rubber. Reverse marks occur when the laser runs over the honeycomb cells. Best Laser Cutter and Engraving Machine Under $500 1.

More content is on the way! Very thin fabrics and some papers can also be cut on the engraving table because they require a very low laser power. The engraving table is a essentially a flat metal surface used more to support the material for engraving only. The thinner the sheet you are cutting, the better the cutting results you will obtain. Birch plywood for instance has such a high moisture content and uneven grain structure that the backing peels off after a few minutes, and sometimes during the cutting process which can make it appear even more burnt than if it wasn’t used at all. Marks also appear from hot debris which glazes or scorches the exhaust-facing edges of the cut line. The following are suggested laser cutter configuration settings for various materials. Due to this, small flare marks can appear on material surface. In this case thinner strips of high tack masking tape are layered in strips to cover the reverse of the material. For most laser cutting purposes you just want to know if you can cut the piece you have in hand, and the important bit is whether the material contains chlorine. Different types of masking tape have varying mounts of tack. There are a couple things you might want to consider. This method of material modification provides a number of advantages such as the ability to quickly change designs, produce products without the need for retooling, and improve the quality of finished products. Adding a focusing lens will provide temperatures in excess of most cutting … This didn’t ruin those projects for me, as I saw it as just a natural byproduct of cutting wood and was used to it. Extremely thin sheets (0.5mm and less) may cut with yellowed/discolored edges. One sort of makeshift measure that seems to work for a lot of people is the use of regular, everyday masking tape that you can find and purchase at office supply or arts and crafts stores. Gas 5. The most significant charring and scorching will appear on chiefly combustible materials. While there was no penetration, it appears that slower cuts or thinner stock would work. Laser cutting of foils, films and membrane keyboards made of polyester, polycarbonate, polyethylene terephthalate and polyimide. I dislike that yellow edge! Low Tech Tape. Protective backing can be used on most materials but not all. Paper for instance needs quite a lot of support as it is not a rigid material. Laser cutting wood is a sublimation process. Laser cutting is primarily accomplished by melt shearing. Polycarbonate is produced using phosgene , which is not really something you ever want to be exposed to. The idea is that you want to cover the entire wooden surface with masking tape prior to cutting your project. Since the exact composition of various wooden materials you will be using is not always known, it’s best to do preparatory cuts before you commence to finish projects. 4 years ago.

Polycarbonate sheet can be cut with industrial cutting lasers however, edges may become amber or brown when laser cut and a clean edge is difficult to obtain. The tackiness of large format protective backing is sometimes insufficient for some materials particularly those with a rough surface. This entry point is most susceptible to damage since it receives the most sustained blast of heat. In some cases the material can be “floated” completely minimising marks on the reverse. The following are suggested laser cutter configuration settings for various materials. But I perfectly understand that sometimes that charring goes beyond the tolerable amount. Markings are an inevitable part of the process but they can be minimised. There is a relationship between the laser power, cutting quality, cutting speed, and cutting thickness. Plastic can be laser cut to: any shape; produce small kerfs of just 0.15mm; cut fine details and the smallest pieces; produce inlays without gaps; avoid burning or breaking; save costs and reduce waste Marking is accomplished by melting the surface of the plastic to provide a slightly engraved mark. One of the most common materials to cut and engrave using a laser cutter is wood. ), so let’s read on to see how to deal with this common issue. Burn marks and heat marks occur in following ways: This differs from material to material. Low tack masking tape should be sufficient for most projects, but there may be some instances where you will want to rely on higher tack tape. Plastics is Laser cut with a power of 100-500w and without cutting gas. Applying the tape helps to limit surface burn marks particularly on the reverse surface. Cutting: Thin sheets of polycarbonate can be cut with our CO2 laser systems, but the material tends to discolor when heated by the laser beam. These stains are not from the laser itself, but are due to the smoke produced from the combustion action caused by the laser. Thanks for visiting craftcutguide! Brand of Acrylic 2. It won’t bother everyone. Polycarbonate (PC) is a durable, impact resistant, thermoplastic polymer. There are 146 more on our website at present.
