laser cutting polycarbonate without burning

Laser will incinerate most flammable materials 3 to 5 meters from beam exit aperture -- without any optics! 0.5 - 2 mm), the darker the laser engraving will be. 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. I'm pretty curious about this picture off of Snapmaker's website (on the page for the 2.0): As you can see, it's listed as an example of what the laser can do with plywood. Quick, clean, accurate and adaptable, laser cutting plastics is the preferred method for many businesses across a wide range of industries. Also, be sure that you are using a DVD burner and not a reader/player. 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. Set the polycarbonate material on a cutting platform, as described in step 3 above. 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. There is a relationship between the laser power, cutting quality, cutting speed, and cutting thickness. Fortunately, there’s a simple, low tech solution for this problem. ), so let’s read on to see how to deal with this common issue. Not all materials react to the laser in the same way. The laser cutting equipment we have for sale at OR Laser is capable of cutting even … There was almost always some level of brown or amber color on the edges. 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. In fact, some laser cutters are not able to cut it because it ruins the lens and requires frequent stopping and cleaning. Laser will incinerate most flammable materials 3 to 5 meters from beam exit aperture -- without any optics! Laser cutting. Polycarbonate absorbs IR strongly, and is a poor material to use in the laser cutter. Compressed air (up to 4 bar / 58.02 psi) is used in most laser cutting applications to remove heat and combustible gases from the top material surface. We love all things crafty. Find out how to laser cut leather in this guide! At the beginning of a vector shape the laser needs to begin firing to pierce though the material. 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. Due to the nature of repeat cutting, residues from materials tend to build up on the honeycomb beds. The right laser optics. 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. How do we laser cut wood without burn marks? 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. Markings are an inevitable part of the process but they can be minimised. Another thing to note is the speed of the DVD burner. This entry point is most susceptible to damage since it receives the most sustained blast of heat. C02 laser cutting is essentially finely burning through a material and engraving is delicately burning into it. Unfortunately the more contact the reverse of the material has with the laser bed the higher the risk of marks on the reverse. or non-organic (metal, plastic, etc. 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. But I perfectly understand that sometimes that charring goes beyond the tolerable amount. Type of Acrylic 3. This is a neat demonstration for showing the potential use as a directed beam weapon! The underside extraction and efficient air assist via the nosecone of all Blu laser cutting machines makes cutting these otherwise difficult materials easy, fast and clean. Like burning with a magnifying glass. A 3000 watt laser can be reduced to 400 watts, but the result is not as good as with a dedicated 400 watt laser. While laser engraving, please pay attention to the following: The finer the details, the shorter the focal length of the lens should be. This is helpful for figuring out where the laser will cut before you run your job on your material. Polycarbonate (PC) is a durable, impact resistant, thermoplastic polymer. Adjust the saw speed so the blade is moving at approximately 12,000 strokes per minute. 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. 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. Smaller Kerf widths are also maintained with compressed air by minimizing the heat of the laser at point of contact with the material surface. 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. As the application continues to be used for many industrial purposes, it’s also growing in popularity … The Harmful Side Effects of Laser Cutting. Paper for instance needs quite a lot of support as it is not a rigid material. 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. In fact, some laser cutters are not able to cut it because it ruins the lens and requires frequent stopping and cleaning. A distinction must be drawn between engraving and/or cutting. Colored acrylics can in most cases by laser cut with excellent result. 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.
