Good Morning America (1989) 3D Printing: how it started

  • Chuck Hull, father of 3D Printing
  • Came up with the idea in 1983 while using

UV light to harden tabletop coatings.

  • Developed many of the concepts and

processes still in use today

  • First commercial 3D printing system in

1989

3D Printing – why all the excitement?

– complexity is for free – Monolithic fabrication of multi-material objects – best option for one-off’s – empowers new designers
