As we said in our previous post, we've got more information on saltwater etching from Bruce Bradley, who's put together a nice instructional video, which we've uploaded to our Youtube channel. Bruce has been using automotive primer as a masking paint for his etching; over here in our lab, we've been using Duplicolor as our go-to brand, but most others designed for sandability and weather resistance are fine. Enjoy the video, and let us know if you have done anything cool with our products yourself!
The L-Cheapo Mk7 is back in stock! We've also made some small changes to the way we build the L-Cheapo Mk7, and would like to share them with you. It's still the same laser; but the next run should get a wee bit better.
We have for you today another submission from Bruce Bradley, the gentleman responsible for the six-year L-Cheapo, demonstrating saltwater etching with his laser. Saltwater etching of conductive metals is a relatively simple electrochemical process. A good Instructable explains the details of the process. The purpose of the laser in etching is to cut the mask material or paint, instead of using a scalpel as in the above demonstration. This allows for complex shapes to be very precisely cut, and with the right mask material, a clean edge mated to the metal.
We had an interesting support ticket come in recently; an original L-Cheapo Mk1 needed a PWM adapter to be moved to a new machine. After running for six years, we thought this venerable laser deserved a salute. We don't play around when we guarantee our product for life. (We sent out a custom-designed PWM adapter, of course).
The L-Cheapo Laser Cutter Module has a new iteration! The Mark 7 is the newest iteration of the L-Cheapo laser cutter, with an even greater peak output than the 10W Mk6.
The L-Cheapo laser cutter is a great tool for artistic projects. Davide Antonello, a graphic designer and artist from Italy, sent us these photos of a monitor he rebuilt using laser cut plywood.
This was the first power output test of the L-Cheapo Mark 2. This solid state laser cutter, and others, are available for under $300.
