Technology has reached a point where everyday individuals can purchase an entry-level laser cutter for an affordable price. We have a list of the very best laser cutter and engraving machines on the market today, for all possible price points. Even if you work in the printing and manufacturing industry, laser cutting and engraving is an entirely different beast. With so many new unknowns you may have no real clue what to go with, how much to spend, and what is right for your business.
The first experiment in laser materials processing which was subsequently to evolve into a significant industrial process, was conducted in May when Peter Houldcroft used an oxygen assist gas to cut 1mm thick steel sheet with a focused CO 2 laser beam. Using archive photographs and early film, this paper will describe the pioneering work on laser cutting using a W slow flow CO 2 laser. This laser was operational in the UK only two years after Patel had demonstrated lasing action from the CO 2 molecule. Early examples of laser cutting will be shown and reference made to the predictions of the early experimentalists. The paper will also discuss the evolution of the fast axial flow CO 2 laser and its subsequent use to produce the first keyhole laser welds.
Clean cutting, accuracy, and precision! These tools offer you endless possibilities to create different things. If you are a DIY enthusiast, you can create simple boxes and engrave graphics deep into the wood.
