●High Precision Module: E40 is a high-power dual beam fixed focus high-precision module. E40 module has extremely small incisions when cutting MDF boards, leather, acrylic, fabric, cardboard and other high-density materials less than 4mm, and the minimum gap between incisions is less than 0.06mm. At the same time, it can carve stainless steel, stone, glass, ceramics and other high-resolution materials with high-precision rendering capability, and the imaging effect is meticulous and accurate ●High Power Module: NEJE E40 adopts NEJEs unique external lens optical compression technology, which makes the focus energy density amazing. The energy density is 2 times higher than that of the 20W optical power module, so it has faster speed and precision in the actual engraving process. The incision in XY direction tends to be uniform. Therefore, you will get a more even effect when drawing lines ●Longer Service Life: E40 module adopts more stable and reliable optical solution, which makes the service life of the E40 continuous cutting mode 40% longer than that of the ordinary laser module, and the service life of the E40 normal working mode (8 hours per day) even reaches 7 years. The NEJE teams goal for E40 is to become the next classic, You can always believe that it will constantly brings you more amazing projects ●Wildly Compatibility: In addition to being compatible with NEJE 3 Max, Plus & Pro laser engraving machines, also has excellent compatibility with other brands of engraving machines, 3D printers and CNC milling machines on the market.Also compatible with mature engraving software on the market (LaserGRBL, Lightburn) ●Professional Technical Support & After Sales Service: NEJE is a manufacturer that independently develops and produces core materials such as laser modules and software, and is committed to providing customers with the best products and services.
