It is one of the main things you should pay attention to when selecting a laser cutter. To determine the future use of the machine, you need to answer the following questions:

The working area of the machine depends on workpiece dimensions.
Some models are equipped with a lifting table function however, it only allows processing thicker materials or cylindrical objects. The size of the working area remains the same.
Laser cutting machines can be divided into three types according to the working area size:
The working area size should always be chosen according to the dimensions of the material to be processed. The cost of the machine as well as the power of a laser source increases pro rata with the size of the working area.
The choice of the power of a laser source also depends on the features of the material to be processed (its dimensions, thickness, and variety). For example, a 40 W laser is suitable for thin non-metallic materials.
In addition, the laser source power determines the machining speed. Laser sources have a quite wide range of power from 20-40 W to 25kW. For manufacturing souvenirs, tabletop models with 40-60 W laser sources are mainly chosen. To cut a 3 mm sheet of aluminium, you will need a laser source with a power of at least 1.5 kW.
