In short, the answer is not at all! Not just it isn't bad, but according to some, it is even helpful to reduce pollution and helps make the world green again. And here is why 1. Production is on a small scale and locally; therefore, no shipping is required (at least not international shipping), which is a tremendous benefit considering that the main source of greenhouse gas is transportation. 2. Less waste than traditional marking, stamping, and cutting. It doesn't leave waste, and it rather makes the material resolve in the air. Additionally, the machine itself does not require a lot of replacement, and one laser tube can handle 15 years of cutting as opposed to blade cutting that has to be replaced often. 3. Energy reduction is a great way to keep our planet green, and when you use a laser cutter, you will use less energy per project. It also can help you sometimes complete your whole project with the same machine, such as cutting, marking, and engraving, so less machinery is used, which means less energy to power up those machinery.
