Always wear red or green goggles when you operate the laser. Remember, Endurance lasers are class 4 item and must never be aimed in any live specie.

Endurance Lasers
for 3D printers and CNC machines

– Compatible with most 3D printers and CNC machines.
– Rated for real, continuous power output.
– Easy to use and install.
– Tested for 48-72 hour nonstop operation.

Endurance can make designs, builds, and delivers powerful solid-state laser add-on modules and a variety of engraving and cutting machines.

Effective laser attachments with different output: 2100 mW (2.1W), 3500 mW (3.5W), 5600 mW (5.6W), 8000 mW (8W), 8500 mW (8.5W+), 10000 mW (10W) 445 nm wavelength that can converts almost any 3D printer or CNC machine into an engraving or cutting machine.

The 20 Watt Endurance Laser
double beam laser attachment

Endurance presents a 20-watt double beam diode solid-state laser attachment for 3D printers and CNC machines.
The uniqueness of the product is that we focus two combined beams at one spot doubling the laser power.

The 20-watt laser attachment consists of 2 x 10-watt modules installed on one aluminum flexible plate.

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

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



The Endurance 20-watt laser addition consists of:

– 2 x 10-watt laser modules
– An aluminum plate to hold the lasers
– 2 x (Laser control board + voltmeter + thermometer)

Power supply

The 20-watt laser operates on 9 – 24 volts. There is no need for an additional power converter.
Lasers power consumption 12V 10A (2x laser control board)
Laser fans 12V 1A / 2A (recommended)

About laser driver & laser control board

A laser driver is one of the most important components in the laser module. The laser driver controls the voltage and the current that goes to the laser diode itself. It is important so that the laser driver sets and keeps the voltage and the current stable. It keeps the laser diode safe. Also, the laser driver turns on/off both lasers at the same time.

We add a Zener diode as an additional laser diode protection.

TTL wires (PWM) are also added to the laser driver. With a TTL (PWM) you may change the laser power (duty ratio) in the range of 3.5V to 12V For 20-watt laser module we use special tuned and set-up two step-down (buck) DC/DC converters with a current stabilizer on board. A buck converter (step-down converter) is a DC-to-DC power converter which steps down voltage (while stepping up current) from its input (supply) to its output (laser diode).
