It is important to understand that the laser from a laser cutter does not directly cut material, and that it works by leveraging the concepts of optic bending and focusing to orient and focus the laser’s power to a single point in or on the stock material. The focal length of the lens in the machine’s focusing head assembly is therefore an important variable to take into consideration for lasering, and as an operator, the distance of the focusing lens to the stock material must be taken into account if you wish to obtain good results. Always remember to focus your laser. Thankfully, laser cutting machines usually come with a focusing tool of sorts to assist operators with the setup of a lasering job.

It is important to remember that a laser cutter focusing head can only move along the X-Y plane. While this may seem like a limitation at first, the focusing head’s movements are very precise and allow for the manufacturing of parts that contain special assembly features, which in turn easily mesh together to result in complex 3-dimensional structures. A good example of such a feature is that which can be seen on-screen. This part holds together by what are called finger joints. Keep in mind that making this part on a laser cutter instead of a 3D printer or a manual milling machine can greatly reduce both manufacturing time and costs.<gallery mode="slideshow" caption="Example of laser cutting images">
