What do you guys think of this kit? I'm thinking about buying it if everything they say is true. I'm not sure if it can cut acrylic like that.

... I won't drive this diodes with >1.7Amps (around 2Watts) for longer time, as they will heat up and degrade with time -- they are designed for 2Watts max.

Cutting clear acrylic isn't possible with 445 nm! - either you'll need dark coloured material (then the 'cutting depth' could be some Millimeters with several passes) -- or better search for a cheap CO2-laser ... somtehing like 40Watts tube with PS for the same price as this module ...

Just look on fleBay -

40w CO2 laser tube - [www.ebay.com]

Power supply - [www.ebay.com]

Water pump - [www.ebay.com]

Head and mirrors - [www.ebay.com]

And from there all you'll need is an XY CNC axis with provisions to mount the laser, head, and mirrors, reservoir and / or radiator for cooling the water, and a table in a vented enclosure, and your set to go. (well, there's a few more odds and ends in there winking smiley)

Here is a video of a nice little DIY setup - [youtu.be]

I planed on attaching the laser to the front of my extruder on my Prusa Mendel.
