About 3.5 watt diode laser attachment

Would you like to turn your 3D printer or CNC machine into an ultimate laser engraving or cutting machine?
In 2015 Endurance invented a way to convert your 3D printer or CNC router into a cutting or engraving machine with an Endurance diode laser add-on. The Endurance laser is the best upgrade for your existing 3D printer or CNC. Add to your 3D printing machine and ultimate ability to cut and engrave.

With a 3.5 watt Endurance diode laser you can engrave faster and cut deeper such materials as plywood, wood, acrylic, cardboard, hardboard, felt, leather, plastic (ABS, PLA) and many more.

The 3.5 watt (3500 mW) diode laser is a powerful and advanced laser to upgrade your 3D printer or CNC router with and is able to create beautiful engravings and laser cuts. It is very easy to install and does not require any special knowledge. It can be installed on almost any 3D printer or CNC mill. If you have any issues during installation or operation, we are always available to lend a hand. We provide an ultimate customer and after-sales support!
