All makers love lasers and so they make nice store instruments. Even low-power lasers can engrave a wide range of supplies. Reducing materials requires extra energy, with the most well-liked slicing lasers being CO2 with energy between 10W-100W. However the small, inexpensive strong state laser modules can reduce some supplies, like acrylic, in case you get a robust sufficient mannequin. If you’d like an inexpensive approach to make use of a type of, then the Mokey Laser v1.0 is value taking a look at.

Lasers like these can engrave and reduce materials, which implies they’ll completely damage you — your eyes are particularly susceptible. In case you’re going to construct one thing like this, be sure you perceive how one can function it safely. It isn’t proven within the video, however it’s best to completely use some sort of shielded enclosure that may deal with the wavelength and energy of the laser you employ. Even with such an enclosure, it’s best to put on the suitable security goggles.

This design cuts prices by using 3D printer-style elements and by omitting the optics which might be crucial for CO2 lasers. As a result of strong state laser modules are so compact, it’s sensible to maneuver them on a gantry in the identical approach as a 3D-printer’s extruder as a substitute of redirecting the laser beam with mirrors and lenses.

The construction of the Mokey Laser v1.0 is 8020 aluminum extrusion, which additionally acts as rails for the V-roller wheels on which the gantry rides. Many of the different elements are 3D-printed, with customary stepper motors and GT2 belts offering movement. An Arduino Uno board controls these stepper motors via a CNC Defend V3 with A4988 drivers. In case you construct this, you’ll have many software program choices. As proven, it runs GRBL 1.1 and that’s suitable with nearly each open supply g-code sender on the market, together with some which might be add-ons for Inkscape so you’ll be able to management the laser from the identical software program you employ to create toolpaths.

The overall construct value with the invoice of supplies introduced is $402.61, which makes this fairly inexpensive for the dimensions and functionality.
