A CO2 laser cutter is a laser cutting machine that utilizes a carbon dioxide laser to cut a variety of materials.
Purists may say you have to have a fiber laser to cut metal, but that's not entirely true.
Rubber bands are ancient! They are inaccurate and are a harbinger of the technology soon to be obsolete. Over time, rubber bands become loose and can lead to reactionary forces and inaccurate cuts.
UV lasers reduce thermally induced material distortion in thermal processing equipment such as fibre lasers and CO2 lasers.
The design of the UV laser makes it a practical solution for marking on plastics and glass.
Over time, the tools you use most often will break. That's a given.
