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 24V 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).

All Endurance driver/laser control boards are very reliable and been tested before shipment.

All you need to know about an Endurance 20 watt (20000 mw) 445nm diode laser module for 3D printer / CNC router and existing engraving frame


In early 2019 Endurance presented 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 on 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.

By focusing two combined beams at one spot you get a higher power & temperature to speed up cutting, engraving and engrave 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 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.

Key features of the 20 watt laser attachment

– Combined high laser power focused at one spot.
– Portable and compatible with many 3D printers and CNC machines.
– Easy to run and mount.

Tech datasheet for 20 watt laser module

It is the same 10-watt laser that is used in this model, that is why a 10-watt laser datasheet is relevant.


20 watt laser beam focusing – all you need to know

The 20-watt (20000 mW) laser is already focused and ready to go. The preset focusing range is around 6-8 cm. You’ll get a note with the laser specifying the focus range for the particular laser module.


What makes it stand out from other models and other suppliers.

Endurance is the first company to present a double beam laser for 3D printing enthusiasts and CNC makers. Unlike the other Endurance models, a 2 x10-watt laser has ultimate power and opens the ultimate abilities of your 3D printer or CNC router.


The uniqueness of Endurance lasers

The Endurance 20-watt lasers are very reliable. Every unit is carefully assembled and individually tested what decreases the probability of defects.

An effective cooling system with manually built heatsinks keeps the laser diode cold during continuous operation. The heatsink is made out of a special aluminum alloy and the laser diode is installed inside and pressurized what keeps the best contact and removes heat very effectively.

All Endurance lasers are tested before shipment. We take care of our customers and offer ultimate customer support by answering any questions about connecting, mounting, pinouts, and generation of g-codes.

Security and protection while operating Endurance lasers

Endurance cares about your safety and your comfort that is why we ship protective goggles with every order. Keep in mind that all Endurance goggles are being tested and have OD5+.
You must also follow basic rules of safety and never use the laser outside your 3D printer or CNC machine, never aim it at anyone.

We recommend wearing goggles all the times you operate the laser.
If you need additional protection we recommend adding a door or a box out of green, red or black acrylic.

If you do laser engraving or cutting using chemically active materials (plastics) we recommend air ventilation to remove hazardous smoke

Compatibility with 3D printers / CNC routers and engraving machines

The Endurance 20-watt laser is compatible with many 3D printers and CNC machines.
The 20-watt laser module is bigger and heavier than the other Endurance models but is still good for installing.
