In August 2015, a Russian entrepreneurial team called Endurance was developed to develop the L-CHEAPO module (priced at $195) to convert a conventional 3D printer into a laser cutting machine that can penetrate 3/16 inches. Thick paper and wood. Since then, they have often been asked whether the device can be engraved on metal such as aluminum. Considering that the melting temperature of aluminum is as high as 600 degrees Celsius (the surface of the aluminum oxide can reach about 1000 degrees Celsius), many people think that this laser adapter is only 195 dollars is unlikely to do this. But in fact, Endurance gives a viable solution. All you need to do is a 9-12 volt charger, salt, insulator (plastic), nails, water, and their L-Cheapo. Laser module. The following steps will give you a quick and intuitive understanding of their approach. First, you need to prepare a bitmap image that lets the laser software convert where it needs to be ablated and which does not. For this device, images that are too complex or have grayscale requirements may not be suitable, as the image below is suitable (see the figure below). Next, you need to use protective film (tape or paint is enough) to cover the aluminum surface to be etched, then the stage on 3D printing mechanism Jianping modified with a laser. The L-Cheapo laser adapter can now be used to etch through the protective film. Keep in mind that the laser power here is not strong enough to etch aluminum on its own, but it can easily pass through a protective film (such as tape or paint), and the rest of the work requires a current-driven brine solution. finished. You didn't guess wrong! Endurance's solution actually uses electrolysis to achieve the etch. Of course, other tools can also cut the protective film on the aluminum plate, but the non-contact L-Cheapo laser adapter is obviously the most convenient. The next step is critical. You need to place the laser ablated aluminum plate in a plastic container filled with saline solution, connect the cathode and anode to its end, and then open the circuit. Once activated, the etch electrolysis process in the solution begins. Depending on the concentration of the solution, the time required is approximately 3-5 minutes. Then turn off the circuit, and the only thing left to do is to remove the aluminum plate. If your steps are not wrong, you should get a good etch. It is undeniable that this is a clever and simple method of etching metal materials, which can be carried out at home or in the workshop. The simple description above also includes the necessary steps of the whole process. However, if you are ready to follow the instructions, I still recommend that you first contact the Endurance team to solve all the problems you don't understand. After all, you are playing with a laser. Click here to go to the full tutorial.
