3D printing may seem like a recent innovation, but its journey began more than 40 years ago. What started as a tool for rapid prototyping is now transforming industries — from healthcare and aerospace to education and fashion. Let’s explore how 3D printing evolved into the powerful technology we use today.
🕰️ When Was 3D Printing Invented?
- The concept of 3D printing began in the early 1980s.
- In 1981, Japanese researcher Hideo Kodama proposed the idea of layer-by-layer fabrication using UV light.
- But the true breakthrough came in 1984, when Chuck Hull invented Stereolithography (SLA) — the world’s first 3D printing method.
Chuck Hull later founded 3D Systems, one of the oldest 3D printing companies in the world.
