Laser engraver: how does it work?

1. Laser engraver: how does it work? A laser engraver exploits the reactions of the materials when they are subjected to irradiation: the irradiation can remove a part of the surface of the material. It causes a scratch or a chemical reaction that creates a new layer with a different color. A laser engraver can process all types of materials, porous and non-porous: paper and cardboard, wood, metals including Memorial plate engraving, ceramics, and glass. Among all, the most requested are the laser engravers for wood and those for metals: the former are appreciated for the contactless processing, the absence of waste material and the range of possible customizations; metal laser engravers, on the other hand, are more versatile and guarantee a clean and precise marking. The advantages of a laser engraving: • Precise, clean, high definition markings. • Wide range of tractable materials, from wood to fabric, from glass to cardboard, from laminates to metals. • Contactless processing, with consequent cancellation of the risk of damaging the substrate. • No chips and dust production. • Reduced wear of laser machine components. • Optimization of time and production costs. • CO2 laser engraver: secondary packaging The CO2 laser engraving is the technology that uses a gaseous source which, once excited, produces a laser beam. It is also the most widely used laser technology for making Steel marking punches. The sectors of application of a laser engraver range from food to pharmaceuticals, from cosmetics to electronics, from automotive to heavy industry. Does it also work on metals? Yes, in the case of lacquered or anodized metals. Fiber laser engraver: high contrast messages: The fiber laser is a semiconductor laser: the resonator element is made up of glass fibers which, when diode pumped, generate the laser beam whose wavelength is very small. This means that the focal diameter of the laser engraver is very small but with very high intensity. For this reason, the fiber laser technology is the preferred one when it comes to marking very hard or plastic metals where a high contrast of the messages is needed. YAG laser engraver: hard metals and plastics: The YAG laser engraving shares some characteristics of the fiber laser engraving - wavelength, application sectors - although it stands out for greater versatility. Particularly used for Control panel engraved and industrial level marking, YAG laser engravers can mark a large number of materials: ABS, acrylics, aluminum, copper, brass, carbides, carbon, cast iron, gold, PA, PC, platinum, steel, titanium, and many others.
