More Saltwater Etching with L-Cheapo!

A Steel Plate Etched by Saltwater
Oct 12, 2020

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!

Saltwater Etching Metal with L-Cheapo

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.

L-Cheapo - Built to Last Since 2014

An L-Cheapo Laser Cutter Module, Original 2014 Model
May 6, 2020

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).
