Laser power: Higher power offers greater flexibility
The most critical question to ask when trying to decide how much power your laser should have, is what will be the most common application you are likely to process with your laser? If you intend to use the laser mainly for engraving, then you can achieve good results with just 30 to 80 watts of power. But for regular cutting of materials and high speed engraving applications, we would recommend laser powers higher than 80 watts. Materials respond in different ways when heat is applied, so having just the right amount of laser power is important to obtain the best results. For example, engraving paper will generally require less power than engraving woods. When engraving acrylic, low power is all that is needed in order to create a uniformly homogeneous, not too deep engraving. But when engraving plastic laminate materials (such as TroLase), higher power enables you to prcoess work far more quickly.
Laser power can easily be controlled from within the software, however, the maximum amount of power available depends on the hardware. The following rule applies: A laser machine with higher power offers greater flexibility because it permits the processing of a wider variety of materials.
