20W TOP Cutting Capability: ORTUR Laser Master 3 LU3-20A takes advanced coupling technology, which compresses the spot to 0.08*0.08mm. It is a great acrylic cutting machine as powerful as an industrial CNC Cutter because of the 20W higher power laser output. This laser engraver can cut 10mm basswood plywood in one pass, 15mm pine board in one pass and 8mm black acrylic in one pass. It is ideal for those who have high requirements for laser machine cutting ability. (The cutting capacity is related to the output power of the laser, not to the power of the machine)

Equipped with 50L Air Assist Pump: Ortur Laser Master 3 LU3-20A equipped with a 50L air assist pump also. It allows you to enjoy precise beauty while increasing laser cutter efficiency and saving time. The laser air assist quickly and efficiently reduces the surface temperature of objects during the engraving and cutting process, resulting in cleaner and clearer edges.

High Precision and 20000mm/min higher Speed: ORTUR 20W laser module adopts the COS chip packaging technology. Four laser chips are welded inside the core of the tube via spatial combining, which further improves the combining accuracy to bring smaller square laser spots (0.08*0.08mm). LU3-20A was upgraded from LU2-10A. It keeps the design of dual fan and built-in air assist and optimizes the layout of the dual fans, which makes it more reasonable and looks pretty. The maximum processing speed can reach 20000mm/min. With such engraving tools, you can complete your engraving artwork quickly and well.
