The wavelength of a CO 2 laser is not suitable for metals and, therefore, cannot be used for applications involving metal cutting or engraving. Therefore, using a K40 laser to print a typical wedding invitation at this speed will take around 10 minutes to engrave one unit, and around 33 hours to print 200 invitations.įurthermore, these laser cutters generally provide a small work area that is suitable for working with objects like leather wallets, keychains, invitations, tumblers, etc. These lasers are ideal for personal use, but if you plan to run a small-scale business venture, these might not be ideal.įor example, a K40 laser can perform clean engravings on thick/dense paper with a cutting speed of around 100 mm/sec. However, the budget-friendly price comes with limited features, which cannot be compared to other expensive laser cutter manufacturers like Glowforge and FSL Muse. This makes K40 laser cutters ideal for beginners and hobbyists who want to explore CO 2 laser cutting on a budget. Most manufacturers now ship these units from various other countries, including the USA, and also provide US-based technical support.

These laser cutters were introduced by Chinese manufacturers to offer affordable CO 2 laser cutters at around $500. K40 is a generic name for affordable laser cutters with around 40W laser power.
