The person most commonly credited with inventing 3D printing is Chuck Hull , who developed stereolithography and built the first commercial 3D printer in the early 1980s.

Quick Scoop: Who Invented 3D Printing?

  • In 1983, American engineer Chuck Hull created a prototype system called stereolithography, using UV light to cure liquid resin layer by layer into solid objects.
  • Hull filed his famous patent “Apparatus for production of three-dimensional objects by stereolithography” in 1984, and it was granted in 1986, often cited as the birth of modern 3D printing.
  • Around 1987–1988, his company 3D Systems released the SLA-1, widely regarded as the first commercial 3D printer.

So when people ask “who invented 3D printing?” the short, widely accepted answer in industry and media is: Chuck Hull, the “father of 3D printing.”

But Was He Really the First?

The story is a bit more nuanced, and that’s where it gets interesting.

  • In 1981, Japanese researcher Hideo Kodama described and patented an early system using UV light to solidify layers of photopolymer resin, a clear conceptual precursor to stereolithography.
  • Because Kodama did not complete all the patent formalities, his system never became the dominant commercial standard, but many historians now highlight him as an original pioneer of 3D printing.
  • A few years later, a French research trio also explored laser-based curing of liquid monomers for rapid prototyping, but their project was ultimately shelved before reaching commercial success.

So:

  • Kodama : early conceptual inventor and pioneer.
  • Hull : first to successfully commercialize, standardize, and popularize 3D printing, which is why he gets the mainstream credit.

Person / Group Main Contribution Year Why They Matter
Hideo Kodama Early UV-curing, layer-by-layer resin system similar to stereolithography. 1981 Often cited as first to describe a modern-like 3D printing method, despite incomplete patent.
Chuck Hull Invented stereolithography, coined the term, and built the first commercial 3D printer (SLA-1). 1983–1987 Widely regarded as the “father of 3D printing” due to patent, commercialization, and industry impact.
French research trio Laser-based system to cure liquid monomers into solid parts for rapid prototyping. Mid‑1980s Parallel pioneers whose work showed similar ideas arising in multiple labs.
Scott Crump Invented Fused Deposition Modeling (FDM), extruding melted filament to build parts. Late 1980s Laid groundwork for today’s most common desktop 3D printers.
Carl Deckard Developed Selective Laser Sintering (SLS), fusing powder with a laser. 1988 Opened the door to industrial metal and polymer powder printing.

Why This Question Is Still Trending

Even in the mid‑2020s, “who invented 3D printing” keeps popping up in tech blogs, forums, and news because the field keeps leaping forward.

  • Recent work ranges from biocompatible micro‑optics for endoscopes to new methods that cut 3D printing waste by recycling support materials.
  • Researchers are also exploring high‑performance materials and faster light-based printers for tissue engineering and next‑gen medical devices , keeping 3D printing in the spotlight as a “future‑shaping” technology.

As new breakthroughs hit the news, people naturally look back and ask how it all started—and that leads straight to names like Hideo Kodama and Chuck Hull. TL;DR:

  • The widely accepted answer to “who invented 3D printing?” is Chuck Hull , inventor of stereolithography and founder of 3D Systems.
  • Historically, Hideo Kodama proposed a very similar UV-based 3D printing concept earlier, so many historians also credit him as a key originator of the idea.
