Cutting Metals With A Diode Laser?

Hobbyist-grade laser cutters can be a small restrictive as to the sorts and thicknesses of materials that they can slice. We’re generally speaking about CO2 and diode-centered equipment here, and if you want to lower non-plastic sheets, you are normally going to be on the lookout toward normal supplies these kinds of as leather-based, materials, and slender wood.

But what about metals? It is a popular beginner’s issue, frequently asked with a resigned glance, that they currently know the solution is going to be a challenging “no. ” Even so, YouTuber [Chad] decided to answer to some responses about the likelihood of chopping metallic sheets utilizing a higher-electric power diode laser, with a easy experiment to basically ascertain what the boundaries really are.

Using an XTool D1 Pro 20W as a testbed, [Chad] tried a wide range of resources together with mild metal, stainless, aluminium, and brass sheets at a selection of thicknesses. Metal shim sheets in thicknesses from just one to 8-thousandths of an inch appeared to be beautifully cuttable, with an acceptable air help and velocity settings, with thicker sheets needing a excellent couple passes. You can surely see the influence of excess heat in the workpiece, resulting in some discoloration and recognizable warping, but all those difficulties can be mitigated. Copper and aluminium weren’t touched by the beam at all, most likely owing to the extra reflectivity, but we do have to marvel if suitable area treatment options could enhance issues.

Definitely, we have observed that diode lasers can have an influence on metals, simply smearing a tiny mustard on the workpiece seems to make marking a snap. Although we’re on the issue of diode lasers, you can get a good deal of mileage from just strapping these a laser module onto a desktop CNC.
