Laser cutting is definitely an amazing technology that’s key today to make correct cuts on flat supplies. It cuts, marks, or engraves materials like wood, acrylic, and metal by giving out a concentrated beam of light through a movable head.
This subtractive machining procedure is great for reducing simple to intricate design into flat sheets associated with material. While there are some laser cutters that may cut material as heavy as 20 mm, most machines work towards materials closer to 0. 5-12 mm heavy, depending on what’s getting cut.
This article will concentrate on cutting wood with laser cutters, but if you need to cut wood thicker as compared with 20 mm, it’s best take into account using a CNC router. That’s since it will take multiple passes to get a laser to cut by thick materials and won’t create a clean cut. A CNC router can easily handle thicker materials, but it’ll build a larger kerf (width) in exchange. (CNC routers also can carve wood while laser cutters engrave fire wood. )
When cutting wood using a laser, there are two primary options from which to choose: CO2 and diode lasers. After providing a synopsis of these two sorts of lasers, we’ll go over safety concerns before engaging in more details about lasers, what they might cut, and how considerably they cost. Then, we’ll talk a bit about different types of woods that you can easily cut, some pre- and also post-processing information, and last but not least, some services that feel free to use if you don’t possess a laser cutter.
With that, let’s jump into the actual lasers!
When using or purchasing a laser cutter, it’s important to know which kind to work with with your project. Almost any laser cutter can cut wood, but not every laser is necessarily used to. It’s always best of choice the right tool to the right job.
Here include the two main categories of lasers:
These lasers can be found in red, blue, and green colors and so are weaker compared to CARBON lasers. When working about wood, it’s best to work with these laser cutter products for etching and marking as a consequence of their power constraints. Some diode lasers have the ability to cut wood, but they’re commonly limited to cutting tiny and soft woods.
These laser cutters come in a variety of sizes and powers. With regards to working on wood, these machines are designed for marking, engraving, and slicing with amazing results.
Another attention is what sort with laser cutter projects you’re keen on working on. If your plan could be to primarily burn pictures or perhaps imagery on wood, you could think about sticking with an affordable diode laser. In the event you want to mark, engrave, and also cut wood, it’s best to think about committing to a CO2 laser cutter.
While particular machines aren’t as powerful as others, they all come with potential dangers. Always remember these lasers might actually blind or burn people. Use proper personal protecting equipment when necessary.
With the three colors they consist of, red diode lasers is the weakest, but can continue to cause vision loss. Green laser diodes is a bit stronger and can certainly blind you with infrared lighting emitted by inexpensive designs. Blue lasers are even more powerful and considered dangerous to the human eye from through 200 meters away!
Each colored diode laser runs for a certain wavelength that you’ll want to know in order to have the right colored safety camcorders to wear.
CO2 lasers are powerful lasers that can burn your skin plus retina by direct and also reflected exposure. These lasers utilize infrared light, which is invisible to the naked eye, to generate cuts. This means you could potentially go blind without realizing you’re looking at the laser beam.
Working on reflective material can as well redirect the beam in other places, resulting in blindness or burns. Protective eyewear for the following laser is almost always clear compared with diode lasers’ red, azure and green safety eye protection.
Not only are this lasers themselves dangerous, but cutting certain materials can lead to the emission of dangerous fumes. Whichever laser cutter you may get, make sure to perform proper research on basic safety equipment and best practices. Information can easily end up being found online in various forums and from vendors, including this laser protection guide.
