neje dk-bl 445nm laser engraving machine is a blue high power engrving machine, It is designed for depth engraving, It's different from neje dk-bl 1500mw 405nm machine.
off-line operation: Support direct offline operation with mobile phone, built-in lithium polymer battery, no external power supply
445nm High Power: The smart 4pin laser head is powerful, but the absorption efficiency of 450nm light wave is a little lower than that of 405nm, If the object is white or through which it cannot be carved, 450nm is easier to reflect, so it is not suitable for carving delicate images of human portraits, if you need engraving depth and line type image, we recommend the 3000mw 445nm machine. if you want engraving human image we recommend the neje dk-bl 405nm 1500mw machine or neje dk-8-kz 1000mw / neje dk-8-fkz 1500mw.
Smart & Funny: Dk-bl is funny, you can take a poto and print it everywhere without any power, because there 6000mAh polymer lithium battery in the machine. you can also draw an image on a whith paper and take a poto to print it.
non-volatile memory: if it is low power, you can get a mobile power supply for a while and continue engraving. if the engraving is interrupted, the engraving can continue after the power is connected.
5v portable charging: 1A or 500ma charge switch design is safe, if you use it by a windows computer, you can charge it on 500ma or 1A, because some old computer only can provide 500ma charge, but most of computer can charge 1A.
High precision: The mechanical motion structure of the whole metal make sure the precision of image engraving, The point distance is 0.075mm, 550x550 pixel, you can disign a image and control the precision at 0.075mm.
Cloud service: NEJE cloud provided thousands of images, you can get it engraving directly.
safe:Can not be directly offline boot, must use a computer or mobile phone boot, to avoid children and animals accidentally boot injury
1. It can not engrave metal, acrylic and any other retardant material. white material doesn't work well.
2. The product is powered by polymer lithium battery of 6000 mah. The yellow light flashing once or twice means the power is low, which needs to be connected with 5v power supply.
3.The product is only suitable for personal diy, because of the speed of carving, it is not recommended for industrial use
4.When the machine is working, it is recommended not to look directly at the laser head, and not to operate the laser head directly by hand
5.Laser diode is a sensitive component, pay attention to prevent electrostatic damage (product includes electrostatic protection design, but there is a certain probability of damage)
6.This model is not suitable for carving portraits, but only for carving line images.(This is due to the 450nm wavelength characteristics)
If there is a customs spot check, the customs duty is borne by the customer,hope you can understand.
Do not accept bad reviews and disputes due to tariffs.
