Comparing laser CNC with wire tip

COMPARING PYROPRINTER WITH LASER ENGRAVER

HALFTONES

Laser CNC draws dots and it can’t create halftones in the image. In other words, the laser puts a black dot or miss it. Any artist knows that the painted shadows in the image create the volume effect and make it “alive”. In many ways, the human brain recognizes the person because of the shadows on his face.

Laser CNC engraver creates a halftones decreasing of the density location of the black dots. That is, instead of the five gray dots laser will draw 2 black dots and 3 dots it misses.  PyroPrinter draws the image without lifting a hot nichrome sting (wire), and changes the time of contact with the wooden surface. If the hot tip is moving fast, the contact time will be minimal. As a result, we get a light tone. If sting will move slowly, the hot soldering iron tip will take longer to touch the wood. So we get black. Because of the large speed range PyroPrinter gets a large range of shades.

 

Speed of burning

Laser CNC burns at a rate of 10 points per second. Thus, a picture size 20*20 cm we burned 10 hours. In this case, the image was quite bright.

PyroPrinter burns formats with the following speed:

— A4 format — 1.5-2.5 hours

— A3 format — 3.5-5 hours

— A2 format — 7-9 hours
