A 3D printer takes a CAD file or a 3D scan and uses it to form an item by adding thin layers of sintering powder or resin until the item is fully formed.Ī laser 3D printer cures the resin into the hardened plastic you’re used to seeing on 3D printed objects. What is a 3D printer and how does a laser come into play? These are reasonable questions.įirst, let’s talk about how 3D printing actually works.
Thicker materials are a bit harder to deal with and you may have some occasional burnt edges. There’s also a risk of toxic emissions, depending on the material. However, lasers understandably use a lot of energy. The biggest benefits include high precision, the ability to work with a wide range of materials and no risk of contamination. You’re probably asking yourself what are the laser cutter’s pros and cons. They work well for reflective materials and hold up longer than crystal laser cutters. They’re cheaper and work well for multiple types of materials.įiber laser cutters– These use fiberglass and are often referred to as solid-state lasers. This amazing technology is credited to Kumar Patel, who created the first Co2 laser in 1963.ĭespite being called a cutter, modern lasers are used to engrave, cut and mark materials.ĭepending on what you want to do, you can choose between three different main types, including:Ĭrystal laser cutters– These cut through thicker materials, but the higher-power requirement means they wear out faster.Ĭo2 or gas laser cutters– These are powered by Co2 and other gases, such as helium and nitrogen. Laser engravers are most often used on glass, wood, gemstone, paper, plastic and metal. If you’ve been wondering what a laser cutter is and why you’d use one, the simple answer is that it’s a great non-touch way to create highly intricate designs with precision. Depending on the laser and the material, the laser might vaporize, melt or burn the material in order to create the design. A laser cutter uses lasers to cut all types of designs and patterns into a material.
