The Eureka Moment

for 3D Printing

7 In 1983, on the night that 3D printing was invented, Chuck Hull
called his wife at home from the lab where he was working. She
changed out of her pajamas and came racing down to the lab.

8 Hull was excited because he had had a “eureka moment.” He
had been working for a small company in Germany that worked

planning, Hall was able to use this technique to create simple
objects. He was the first person ever to make a 3D-printed
object. Hull got a patent for his invention—at the time, called
“stereolithography apparatus,” or SLA.

9 Hull formed a company called 3D Systems in 1986, and
was able to sell the first 3D printers starting in 1988. Other
companies began to produce 3D printers as well, and scientists

and engineers began to experiment with this new tool for
creating objects.
