1500mW LASER diode modules are a very inexpensive accessory for cheap CNC machines, and are ideal for things like burning images and text onto wood. However, with a little care they can also be used for cutting thin materials. One of those materials that is likely to be widely used, especially when crafting or carding, is white paper. So I decided to see if I could cut some white paper, which was around 80 gsm (grams per square-meter) and came from a notebook.
Being white and fairly smooth it’s actually quite difficult to cut as it reflects a lot of the LASER energy. But with some care focussing the laser dot to be as small as possible, and adjusting the height of the LASER (as they often have short focal lengths so shouldn’t be too high), I was able to do quite a nice cut as shown in the picture above (100% power and 100 mm/min). Fortunately, the dot on the 1500mW LASER is quite small so I thought it could be fun to see how small I could cut out my dragon and the result is in the photo below: at less than 20mm wide the cut quality was still quite good.
