Types of Laser Equipment
Laser Sheet Cutters
Laser sheet cutters are precision woodworking tools used to precisely cut and engrave wood, plywood, and other materials using a concentrated beam of light. The designed laser works with a computer-guided mechanism to precisely cut out shapes or engrave complex patterns with precision. Laser sheet cutters can be used with a variety of materials, including plywood sheets with a wood grain, as well as a number of different types of metals.
CO2 Lasers
CO2 lasers are one of the most popular types of laser cutting equipment used for cutting and engraving wood. This type of laser operates by generates a beam of infrared light that is focused on the wood cutting surface with a lens. By focusing this light, it increases in intensity and can burn or cut through material.
CO2 laser cutting wood is suitable for a range of wood materials, from plywood sheets to thicker boards.
CNC Laser Cutters
CNC Laser Cutters are by far one of the most popular laser cutting tools available today. CNC stands for “Computer Numerically Controlled” and these lasers use a beam of light that is focused through a lens to cut or engrave on almost any material. These machines are used by hobbyists, students, and professionals alike because of the accuracy, speed and versatility they offer.
Materials
Plywood
Plywood is a great material to work with when laser cutting, as it offers a wide range of customizations and cutting possibilities. When looking to use plywood with a wood laser cutter, it is important to keep a few key things in mind. First, always check with the manufacturer of the plywood to make sure that it is safe and compatible with laser cutting.
Basswood
Basswood is an ideal material for laser cutting, engraving, and etching due to its unstained, uniform, and pliable nature. This type of wood is often found in hobby and craft stores, and it’s commonly used for model building, art, and certain types of woodworking. This wood is optimal for laser cutting wood sheets because it can be laser-cut without breaking, shredding, and splintering.
Its nature makes it suitable for creating intricate shapes and designs.
Other Types of Wood
When it comes to laser cutting wood sheets, materials, there are a few different types of wood that you can use. Plywood sheets, which can come in a range of thicknesses, are a great option for laser cutting. Plywood is a great option for laser cutting because it is very dense and it can handle the intense heat from a laser cutter.
Hardwoods, such as Oak, Cherry, and Walnut, are also a good option for laser cutting. These can be stained, painted, or sealed depending on the project.
Design Tips
Minimizing Vertical Features
One of the key things to consider when using laser cutting wood sheets is minimizing vertical features. When cutting perpendicular to the wood grain, it can reduce the risks associated with the produced debris. Vertical features can cause burning and charring of the wood, which can be difficult to clean up.
Additionally, these vertical features can create small areas of heat that can create a weak cut. When working with a laser cutter, a good rule of thumb is to focus on cutting horizontally with the grain. This way, the cutter can get deeper into the wood without having to worry about burning or charring.
Additionally, it helps to keep the edges of the cut neat and clean without having to worry about chipping during engraving.
Clarity of Design
When cutting wood sheets with a laser cutter, it is important to have a clear and consistent design. Clarity of design means that you can clearly and easily identify the design elements you want to cut before laser engraving them onto the wood. This is especially important if you are working with a laser that has a lower power output than other machines because it can be harder for the laser to penetrate a denser material, such as plywood.
Additionally, if you are cutting with a laser that has more power, you can achieve better contrast and depth when engraving.
Setting up the Machine
Laser Power Settings
When it comes to setting up a laser cutter for cutting plywood sheets with a wood laser, one of the most important factors to consider is the laser power settings. This setting significantly impacts the speed and accuracy of the laser’s cutting ability, so it’s important to make sure it is adjusted properly. The power of a laser is measured in milliwatts, and the output of the laser is often adjustable.
Speed and Focus of Laser
When it comes to laser cutting wood sheets, the speed and focus of a laser cutter are crucial components to get the best results. For example, when cutting plywood with a laser, the speed needs to be adjusted depending on the thickness of the sheet. Slower speeds will enable the laser to be more focused and provide a more accurate cut, while a higher speed will result in a faster finished product.
Additionally, the focus of the laser is important to ensure the detailed cuts are precise and smooth.
Cutting the Wood Sheets
Choosing the Right Settings
When it comes to using laser cutting on wood sheets, choosing the right settings is key. Plywood sheets are usually made of thin layers of wood bonded together, so you need to tailor your settings to make sure you get an accurate and clean laser cut. When selecting settings, you need to consider the type of wood you’re going to engrave with a laser.
You will then need to set the power levels accordingly.
Tips for an even Cut
When it comes to cutting plywood sheets with a laser cutter, the process can be quite tricky. It requires precise accuracy, complex geometry, and a lot of patience. But, with a few tips and tricks, you can make the process a little easier and ensure an even cut.
One of the most important tips is to make sure that you are using the right type of laser cutter. For cutting wood, you want to use a CO2 laser and not an Nd:YAG laser.
Tips for Avoiding Debris/Smoke
When laser cutting wood sheets, it is important to take safety precautions to protect yourself from fumes and flying particles of the material.
