Engraving 100% done, cutting 100% done, total time 1:01:45
And the business keeps changing. The market and the customer demand flexibility from suppliers; meanwhile, the engraver has to keep an eye on the profitability of his/her business. Being successful requires meeting the needs of customers and being profitable at the same time. Having high laser power of your laser system helps you to break the limitations you might meet now.
The Impact of More Laser Power

Generally, you can say that more laser power means more productivity and more flexibility for almost all laser engraving and cutting applications. In laser theory, engraving and cutting speed increases linearly to increasing laser power. That’s true for non-heat conductive materials like rubber, wood, stone, ceramic, tiles, glass and any plastics—which means acrylics or laserable plastics. In these cases, more laser power enables the laser user to process his/her materials faster.
What Does This Mean for My Application?

On acrylics, the benefit of high laser power is very obvious. A rule of thumb says 10 watts provides the ability to cut 0.04 inch thick acrylic. E.g. 30 watts would give perfect cut quality and good productivity on a 1/8 inch sheet of acrylic. If you increase the laser power to 80 watts, you can process 5/16 inch perfectly in the same time as 1/8 inch with 30 watts. In addition, you can process the 1/8 inch more than two times faster with the high-power system.
Now let’s take a sample application: Acrylic dimensional lettering with flame-polished edges; a sheet of acrylic, 36x24 inch, 5/16 inch thick, fully nested with 64 pieces of 4 inch tall letters. On a 30-watt system, this job would take 4:18:00; the 80-watt system will cut it in 1:47:00 (See Photo 3).

Now, the assumption might be that sensitive materials can’t be processed with high laser power and that applications like engraving FlexiBrass or paper are restricted to low laser power. But that is not the case. Photo 4 and Photo 5 show two sensitive applications, both processed with an 80-watt system. The engraving quality is spotless, and the high laser power does not show any negative effects.
