3D Tech Works 2.8W, 3.8W Laser Modules
3D Tech Works is pleased to announce the availability of a new 2.8W Blue Laser Module.  This module has enough power to engrave almost any material, except metal, and to do limited cutting of thin materials such as Balsa wood, thin plywood (1/8"), acrylic, foam, etc.

The laser module simply bolts onto the front of the standard router mount, and the controller mounts on the top of most Z Axis beams.  All electrical connections are by simple plug ins, which allows the unit to easily be installed and removed to swap out for the standard router.

The system includes the 2.8W Blue Laser, mounting with forced air cooling, the control module, and a power supply for the laser.  It also comes with a pair of Laser Safety Goggles, which are an absolute must.  The system comes completely wired, but the user must add a couple of wires for power and Laser Enable to his existing machine.  If the Laser Module is ordered with the machine, the installation is included.

The Laser Control Module has connections for an interlock loop, which can be used for an E-Stop switch or door interlocks for the laser.  It also powers the Laser Module, the Fan, and has a keyswitch that disables the laser so the user can be confident no one can use the laser without authorization.  LED indicators indicate the status of the Laser at all times.   In addition, a safety power interlock disables the laser in the event of a power failure, the system must be reset if the power fails when the laser is on.

A separate 12V power module is included to power the Laser, it can be plugged in anywhere.  

New!  A 3.8W Laser module is now available for extra cutting and engraving power!

Free Software is available to run the laser, and the latest version of GRBL and GRBL Panel have Laser support.

Warning:  Lasers are extremely dangerous, and at these power levels can cause extreme skin burns and destroy your eyesight in seconds.  We take no responsibility for any injury sustained as a result of purchasing and using this equipment.
