Good ventilation is always 100% necessary to achieve a perfect cut, while a lack of ventilation could cause vapours to ignite and start a fire. Caution: Don’t forget to mirror the job! This week, we will be doing an in-depth training video on finding the right laser settings for your Trotec laser machine. Due to this manufacturing process, the thickness tolerance is significantly higher - about 15% - which needs to be considered when completing applications with plug connections. Laser engraving also yields better results than with extruded acrylic, with a perfectly white engraved image being created. Ready to put your Glowforge, Mira, Thunder, Trotec, or Epilog Laser to use but don't want the wait for shipping from those other guys? Our TroGlass product line includes cast acrylic sheets designed for laser processing. Smaller parts might slide around or fall through the gaps of this table, so we don't recommend its use in these situations. This is what we call a 'lead-in'. Extruded acrylic is manufactured through an extrusion process that pushes an acrylic mass through a nozzle resulting in the desired thickness. Extruded acrylic is produced via an extrusion process. The lead-in should always be about 3-8mm outside of the finished contour and should make its way towards the actual contour in a straight, smooth line. Choosing the right lens is key when laser cutting acrylic. Laser engraving produces a white or clear engraved image, depending on the chosen settings. However, these configurations are only recommended for acrylic up to 8mm thick. In fact, it is paramount when completing any kind of laser application.

It's very useful to have a basic knowledge about these differences when deciding on a suitable acrylic for your chosen application. 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 vertical marks along the cut line. Even when using printed acrylic, the product can look much better when printed on the reverse. In principle, all Trotec CO2 laser machines are ideally suited for laser processing acrylic. Again, thicker materials will require a lens with a longer focal length. Typically, smaller parts can be unstable or tip, and are not suitable for the design of this specific table. Advantages of a Trotec laser. Here, you will be able to read all about how to select the correct materials and settings to achieve the best results. This is because the vapours within the machine can be dangerous to you, your machine and the environment. This production method creates different mechanical properties in the x and y directions for extruded acrylic, and it offers a lower thickness tolerance of ±5% making it well suited for applications with plug connectors. TroGlass Frosted is a heavy-duty cast acrylic glass with a matte, roughly structured surface on both sides (“sandblasted finish”), and this allows an anti-reflex surface. When the laser machine cuts into a material, it becomes visible from this point and cannot be avoided. You will be left with an elegant, white engraving result. Laser cutting cast acrylic creates burr-free cuts on both sides. In principle, all Trotec CO 2 laser machines are ideally suited for laser processing acrylic. Available in a wide variety of colors, textures and transparencies, TroGlass products combine benefits such as clarity and excellent light transmission with advantages such durability and scratch resistance. Alternatively, if the nozzle has a diameter that is too small or if the air pressure is too high, the result will be dull and milky edges from the material cooling too quickly. It also requires much less power than cast acrylic. You'll want them to be perfect to achieve a high-quality result, but also to remain safe. The frosted surface, combined with the intrinsic hardness of cast acrylic, allows applications where … Depending on the size of your machine and application, there are many different tables you can choose from. If the frequency is too low, fine ridges or 'chatter marks' can become visible on the cutting edges. The Trotec acrylic product assortment contains a large selection is exciting acrylic sheets. We suggest moving the focal point to the interior of the material whenever it is more than 6mm thick. Laser cutting cast acrylic creates burr-free edges on both sides, and laser engraving yields beautifully white engravings which are otherwise impossible with extruded acrylic. Utilising an appropriate exhaust system is extremely important when cutting any kind of acrylic material. Contact us and one of our top qualified and highly motivated laser experts will gladly assist you with any additional questions or problems that you have. Everything about TroGlass in the Trotec Webshop, Trotec Laser Engraving and Cutting Technology. For thicker acrylic, always use alternative cutting tables. A starting point that begins on a straight line or in the middle of a curve will be especially noticeable, and we recommend a starting point that is positioned in an unnoticeable corner. However, it is important to note that they behave quite differently to each other when laser processed. By mirror-engraving the back of the material with the appropriate design, the colored layer is removed during the engraving process and the area of the material becomes transparent. When extruded acrylic is laser cut, you will be left with a beautiful flame polished edge that is much less sharp on one side. CO2 laser machines are exceptional at laser cutting, marking and engraving acrylic, and are the ideal solution for creating displays, illuminated signage, decorative objects, toys and more. The process from sheet stock to finished award is a long one, but with the right settings on your equipment, you can create beautiful finished acrylic pieces that are perfect for various applications.

Starting points that are situated on a straight line or in the middle of a curve are especially noticeable. You should start high on cast acrylic (10 to 20 khz); and start lower on extruded (2 to 5 khz). Marking laser stations with galvo marking heads. We make tags, ADA signs, and larger format signs with your products. When flame polishing acrylic it is essential to cut the acrylic using a cutting table. Laser engraving on the back side of your acrylic workpiece will give the finished product a higher quality, and the engraving will be more resilient to external influences. This will give your material enough time to completely cool off, meaning you will achieve glass-clear cutting edges every time. The cutting sequence for individual objects can also have a heavy influence on the quality of larger quantities. The cutting sequence is visible in the level window of your graphics software (e.g., Adobe Illustrator, CorelDraw, etc.) Located in Spring Branch, near I-10 and 610, you can swing by and grab just what you need. Firstly, the number of nodes in the cutting contour needs to be reduced to a minimal amount, which allows the laser to process homogeneously without any necessary stops.
