The origin of laser machine
Many people think that the first laser equipment was invented by Theodore Maiman in 1960. But in fact, Gordon Gould is considered by some people to have invented the first laser lamp. Gould expounded his invention in 1958, but failed to submit a patent. Until 1959, his patent application was rejected, and then other companies used this technology. Gould finally won his patent battle at 1977. )
The birth of LMI
In 1970s, the founder of LMI(Laser Machining Inc) bought a laser machine and tried to make a new engraving machine on different platforms, which was successful. It was at this time that the first user bought a laser engraving machine.
The appearance of internal carving machine
In EJ》(Engravers Journal), a leading professional sculpture publication in the United States, it once said, "In about 12 years, LMI almost created the method of DIY (indoor) laser sculpture."
My English is not good, but it seems that the first appearance of the internal engraving machine is related to the extinct LMI company.
