In early 1980, an engineer named Chuck Hull came up with an idea for his boss: to make a machine that prints out objects you can hold in your hand. His manager dissuaded him. After all, the company is producing UV lights, not \"Star Trek\" replicators. But in the end, the two reached a compromise: Hull dedicated his strength to the company\'s lamps and lanterns every day; In the evening, he will piece together his dream machine. At the beginning, ultraviolet rays gave Hull insight. The factory uses these lamps to harden the plastic finish onto the table top or rubber tile. Hull realizes that he can etching plastic layers into whatever shape he likes with UV rays, and then stacking those layers into 3-D object. At the beginning, he had to write code to tell his machine how to cut each layer, which was a hard process. \"I was limited to a fairly simple shape,\" he said . \" One day, for example, he brought home a snack. The size cup for his wife. \"It looks like something you bought to wash your eyes at a pharmacy,\" he said . \". His first 3- \"D printer\" is so messy that it looks like it was mailed Just like some of the devices they use in the movie water world. But in the last century 1980, the printer has developed into a product that can work, although it costs several hundred thousand dollars. Because the printer was too heavy to drag the demo, Hull made a home movie for executives. Still, he said, \"We have a huge response. Especially in Detroit. \"At that time, AmericaS. \"The auto industry is already far behind Japan, and auto companies are in desperate need of a secret weapon,\" said Hull.
