1. The History of 3D Printing

Early Innovations (1980s)

1981: Hideo Kodama patented the first rapid prototyping system (UV-cured resins).
1984: Charles Hull invented stereolithography (SLA) and founded 3D Systems.
1988: Fused Deposition Modeling (FDM) patented by Scott Crump (Stratasys).

Industrial Adoption (1990s-2000s)

Used primarily for prototyping in aerospace/automotive.
2005: Dr. Adrian Bowyer launched the RepRap Project, enabling low-cost DIY 3D printers.

Mainstream Revolution (2010s-Present)

2012: First 3D-printed prosthetic limb implanted.
2014: Desktop Metal pioneered metal 3D printing for mass production.
2020s: Bioprinting organs, construction 3D printing, and AI-optimized designs.

Today, 3D printing disrupts healthcare, construction, fashion, and food industries.
