who invented 3d printing
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.

|---|---|---|---|
| Hideo Kodama | Early UV-curing, layer-by-layer resin system similar to stereolithography. | [1][4]1981 | Often cited as first to describe a modern-like 3D printing method, despite incomplete patent. | [7][1]
| Chuck Hull | Invented stereolithography, coined the term, and built the first commercial 3D printer (SLA-1). | [6][3][2]1983–1987 | Widely regarded as the “father of 3D printing” due to patent, commercialization, and industry impact. | [3][2][1]
| French research trio | Laser-based system to cure liquid monomers into solid parts for rapid prototyping. | [7]Mid‑1980s | Parallel pioneers whose work showed similar ideas arising in multiple labs. | [7]
| Scott Crump | Invented Fused Deposition Modeling (FDM), extruding melted filament to build parts. | [2][7]Late 1980s | Laid groundwork for today’s most common desktop 3D printers. | [2][7]

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.
