20 watt (20000 mw) double beam laser attachment for metal etching. Compatible with all CNC machines


SKU: 20watt Categories: , ,


Endurance presents 20 watt double laser beam system for efficient laser engraving. An effective tool for laser etching / engraving / marking.

20 watt (20000 mw) double laser beam system allows combining 2 beams together under a small angle. By combining two-beam together – it increases power density on a spot and allows quick and efficient laser engraving / etching / marking on all surfaces without engraving paste (except brass and copper). For brass and copper, you would need engraving paste such as Cermark or Dry Lube Moly.

Key features about 20 watt (20000 mw) diode double beam laser

  • The first and unique double-beam laser for 3D printer / CNC machine.
  • Up to 20000 mW real optical laser power.
  • Fast and easy engraving on metallic surfaces, stone, and ceramics.


About the 20 watt blue diode Endurance laser attachment

Endurance presents 20 watt double-beam diode solid-state laser attachment for 3D printers and CNC machines.
The uniqueness of the product is that we combine two beams in one spot doubling the laser power.
20 watt laser attachment contains out of 2 x 10 watt modules installed on a one aluminum flexible plate.






By combing 2 beams in one you get higher power & temperature in a spot that enables faster cutting, engraving and enables engraving on metallic surfaces without additional chemicals.

An Endurance 20 watt semiconductor laser add-on device is one of the most powerful units on the market with 445 nm wavelength while having relatively small sizes which enables easy installing on almost any 3D printer and CNC router.

2 x 10 watt lasers are aimed in one spot by adjusting laser direction over X & Z axes using M6 and M4 screws on the aluminum plate which holds both lasers very tightly.

In the parcel

We ship everything you need to get started. It will take 5-15 minutes to mount and wire the laser to your 3D printer or CNC machine.



Plug and play

All Endurance lasers are plug and play. Just mount the laser to the spindle or extruder without removing them. Connect wires to the fan / spindle / laser pin on your board.
Generate a g-code and run the laser from your computer or SD card.



The Endurance lasers are sold “AS IS” and in this case they there is no need for mandatory certification.


Tests and proof of work

All Endurance lasers are assembled and tested manually which reduces the risk of failure. Every single laser is been tested before shipment on a special stand.


Taxes and duties

All prices include all sales taxes and do not include import duties.


Support & help desk (pinouts inquiry)

Get an instantaneous help over any messenger indicated in the top (under phone numbers).


Laser Safety and security

Your safety and security is our top priority. All Endurance lasers are shipped with protective goggles. Operating lasers wearing protective goggles is secure and harmless.
However, if you want additional protection you may add an acrylic plate or window to your 3D printer or CNC router. It should be made out of black, green or red acrylic. It will not let the laser light go out and will make laser working more comfortable.
All Endurance lasers are class 4 lasers.
