You should cut clear acrylics at 1 8 39 41 power while doubling the power for.
Minimum laser power to cut metal.
1in 2 645mm 2 a 100 watt laser can achieve a power density of 1550 watts mm 2 in a spot size that is 0 6452mm 2 a spot size that is 0 6452mm 2 has a diameter of of 28mm or 280 micron using area pi d 2 2 280 micron.
In this age of cnc machines laser cutters capable of cutting through metal are still too expensive for the average hobbyist.
You can buy low power machines less than 100 w fairly cheaply but these will hardly scratch a metal surface.
This video shows the laser cutting 100 1 8 holes in 18 gau.
The following are the minimum power ratings we recommend for cutting into materials like wood and plastic.
Laser cutting power speed.
The relationship between laser wattage to cut speed is not linear for a number of technical reasons.
By far acrylic is the cheapest material to laser cut.
30w 1 8 3 4mm 40w 5 6mm 50 60w 3 8 10mm 75 120w 13mm these values can vary significantly due to different types of materials different focal lenses alignment of optics etc.
Under certain plate thickness and cutting speed there is an optimal range of laser power.
Mike klos laser mechanisms converting to millimeters that s 1550 watts mm 2.
Sheet metal cutting requires a power density of 10 6 watts in 2 source.
The laser power has a great influence on cutting thickness cutting speed cutting width and cutting quality.
Generally speaking the larger the laser power the thicker the cutting board and the faster cutting speed.
