How large are your production runs? 3.) How do you want to use your laser, and how much laser power is necessary? e size of your material determines the size of the laser machine that you will need, but batch size may also be a factor. For example, if you are process- ing a large order with multiple parts, they can be processed in one job with a larger working area, saving time, and increasing productivity. "The most important criteria when selecting the power of your laser machine is the primary application you will process most frequently with the laser," explains Stevens. "If the laser is mostly used for engraving, you will achieve good results with laser powers between 25 and 80 watts and will not require higher power." For laser cutting or high-speed applica- tions, Stevens recommends a laser power of more than 80 watts. "Every laser varies between type, model, and manufacturer, so make sure you not only have the space for a large piece of equipment, but also the electrical and ventilation requirements," says Stevens.
