3D printing, sometimes known as additive manufacturing, stands as a monumental leap in technology that allows us to transform digital designs into tangible objects. The limelight for this invention often shines on Charles Hull, who introduced stereolithography in the 1980s. Yet, some also credit Dr. Hideo Kodama for inventing an early rapid prototyping machine in 1981. With such a rich history, one might ask, “who invented 3d printing?”

Charles Hull The Father of 3D Printing
Charles Hull is celebrated as the father of 3D printing. In 1983, he conceptualized and pioneered the stereolithography (SLA) process, using a laser to harden liquid resin layer by layer, forming solid objects. His groundbreaking innovation didn’t stop there; in 1986, Hull founded 3D Systems Corporation, aiming to commercialize SLA technology.

Dr. Hideo Kodama The Early Pioneer
Before Hull’s invention, Dr. Hideo Kodama had already made strides in the realm of 3D printing. In 1981, he developed one of the first rapid prototyping machines. This invention, which utilized a resin solidified by UV light, laid the foundation for what we recognize as 3D printing today. However, his brilliance didn’t get the same commercial recognition, primarily because he didn’t patent his invention.
Dr. Adrian Bowyer The RepRap Project
The world of 3D printing owes a lot to Dr. Adrian Bowyer as well. He initiated the RepRap Project, an open-source endeavor to produce self-replicating 3D printers. This project aimed to make 3D printing accessible and affordable, fostering countless innovations in the process.
The Formation of 3D Systems Corporation
In 1986, Charles Hull secured a patent for his stereolithography. That same year, he established 3D Systems Corporation, which launched the SLA-1 in 1988, marking the debut of commercial 3D printing technology. This innovation was soon adopted for rapid prototyping across various sectors like aerospace, automotive, and medical.
The Debate Charles Hull vs. Dr. Hideo Kodama
Who truly invented 3D printing? While Charles Hull is credited for the commercial advent of 3D printing, Dr. Hideo Kodama undoubtedly played a pivotal role in setting its foundational stones. Both contributed immensely, and perhaps the credit for “who invented 3d printing” can be shared between these two luminaries.
The Early Concept of 3D Printing
Rewind even further, and we find Murray Leinster’s 1945 short story “Things Pass By,” envisioning a machine converting digital designs into physical objects. Though purely conceptual at the time, this vision set the stage for what would later become a transformative technology.
Different Methods of 3D Printing
3D printing isn’t monolithic. Several methods exist, each with its own merits:
- Stereolithography (SLA): Uses a laser to solidify liquid resin layer-by-layer.
- Fused deposition modeling (FDM): A heated nozzle extrudes thermoplastic filament, forming objects layer by layer.
- Selective laser sintering (SLS): A laser fuses powdered plastic or metal, crafting solid objects.
- Digital light processing (DLP): A projector methodically cures liquid resin.
Conclusion
Tracing back the annals of 3D printing history, we see the monumental roles played by Charles Hull and Dr. Hideo Kodama. Their pioneering work has given rise to an industry that continues to reshape the way we design, produce, and perceive objects.
