A friend who recently acquired a CO2 laser cutter for his school recently sent me a message. “What is the difference between a laser that will cut metals and one that won’t?”. I thought this is a good question, as the answer will help with understanding how to work with many materials.
Recently I have been building a train set, I will blog the progress, in six parts, highlighting how I get certain things done.
I needed some fan guards for my arcade machine and for a neat little entertainment centre hack. Playing around I made a fish-eye honey-comb screen that looked pretty good. The pattern has larger holes near the centre of the fan and smaller holes where it counts.
Laser engraving text on acrylic / perspex does not create a lot of contrast. This leads to the subject of painting text on the acrylic. I have developed some useful methods of achieving this that I thought I would share.
