We strongly recommend that you wear safety goggles when working with laser equipment. However, you can engrave anodized aluminum with a diode, CO2, or a fiber laser. The depth of the embossment (engraving) depends on the type of the processed material, processing speed and power of the laser. Getting started with Endurance diode lasers - focusing, settings, parameters, misc, How to connect the laser to 3D printers and CNC machines, How to connect the laser to your CNC machine or 3D printer. in the case of cutting the laser beam goes through the thickness of the material. WebProduct DetailsBring style and sophistication to office signage or special occasions with these engraved metal signs. There are 3 metal colors and engraving combinations available. Get the bubbles of air you see under the soaked napkin out as good as possible, so the soaked paper is evenly spread on the metallic surface, but get sure not to tear it apart. Glowforge is a good option for engraving anodized aluminum (and aluminum in general). We always recommend engraving a serial number and/or other identifying information on 80 percent lower receivers. You can easily get the machine for $800 to $1,500, depending on the features and other specifications A diode laser can also engrave other materials, such as solid wood, plywood, acrylic, ceramics, glass, stone, metals, etc. You can also get the infrared laser module, which is specifically made for metal and plastic engraving. Most projects utilize 60-watt CO2 laser or 30W Fiber Laser. You can choose between a handsome black aluminum with gold or silver engraving, or Noteworthy is the capability of the laser to remove rust (at minimal power and maximum speed using a 30 Watt Raycus + Sino-Galvo; or at moderate power and maximal speed with a 10 W DPSS). A diode laser is the most cost-effective solution for engraving anodized and powder-coated aluminum. It is corrosion-resistant and easy to engrave. The term anodizing refers to an electrochemical process that adds an oxide layer on aluminum. Both machines are compact and can be used inside your home or garage. YAG (for yttrium, aluminum, garnet) is a crystalline, solid-state laser that emits a wavelength of 1.064 micrometers (1064 nanometers). However, with slower speeds and more laser passes, a 10-watt diode laser will get the job done. Your Snapmaker lets you turn your ideas into reality. If so, please fill in the form, and we will help you with advanced solutions from Endurance. Depending on the metal type and laser parameters, it is possible to get either black or color marking.

Anodized aluminum has an extra oxide coat which makes it a very good material for laser engraving projects. Anodized aluminum comes in various colors, offering more design flexibility. To increase the processing speed you need to have a galvanometer option (Sino-Galvo SG7110). With clear anodic coatings, the depth of color (usually shades of gray) is dependent on both the alloy and temper of the part being engraved, as well as the anodic coating thickness. The processing procedure: a metal workpiece is covered with acetone-soluble paint. Also depending on the wavelength of the diode you may not get a perfect black to white colour change might be a bit grey. Dry moly lube is a little messy but works well.
