15 watt (15000 mw) DUOS DIY real rated power output laser module. A DIY version – light and compatible with all frames.


SKU: 15wattdiy Categories: , ,


Improve your 3D printer / CNC gantry/engraving/cutting machine with a 15-watt (15 000 mw) real laser power.

Our customers are happy with our 15 watt (15000 mw) 445 nm blue diode “DUOS” laser head DIY version

“1st Cut Tests (with air assist) of dense 1/8” Balsa Using Duos 15 Watt DIY Kit. Almost through cut with 1 pass at 90% power with FR of 15 ipm. Complete Through cut with 2 passes at 70% power with FR of 15 ipm.
Would have taken 15 passes with JTech 3.8 watt laser (and air assist).
I’m extremely happy with the power increase and laser dot size. Appears to be just as tight as my single 3.8 watt JTech Photonics laser.

Will cut kit plane as next test.”  by Reginald Jones
