The Early Pioneers of 3D Printing
While 3D printing has recently risen to fame due to its many practical uses and applications, the technology behind it has existed for many decades. In fact, it was in the 1980s when the first ever patent for 3D printing was filed by Dr. Chuck Hull, co-founder of 3D Systems Corporation.
Dr. Hull’s invention, which he called stereolithography, works by turning digital design blueprints into physical objects by layering liquid material on top of each other, and then curing them to turn them solid. This allowed for a level of customization and complexity in the manufacturing process that traditional methods just could not match.
Though Dr. Hull’s work was groundbreaking, other inventors in this field were also making significant strides in the technology. One such inventor was Hideo Kodama, a Japanese researcher who filed the first patent for a 3D printing technology that used photopolymers to create solid objects in layers. Kodama’s invention was a major leap forward, as it allowed for the creation of much larger and more complex objects than had been possible before.
Another pioneer of the technology was Carl Deckard, who in the early 1990s developed a process known as selective laser sintering (SLS). This method uses lasers to heat and solidify powdered material into a specific shape or design. Like stereolithography and Kodama’s invention, this allowed for complex and customizable manufacturing that revolutionized the industry. In fact, Deckard’s SLS process is still used today in a variety of applications, from aerospace to medical implants.
While these early pioneers of 3D printing helped lay the foundation for the technology as we know it today, it was not until the early 2000s that 3D printing really began to take off. Thanks to advancements in computing and digital design, as well as a growing community of hobbyists and enthusiasts, 3D printing became more accessible to the masses. As the cost of printers continued to fall, more and more people began experimenting with 3D printing, and using the technology to create everything from simple toys to complex prosthetic limbs.
Today, 3D printing is a multibillion-dollar industry with countless applications across a wide variety of industries, from manufacturing to medicine. While the technology has come a long way since the early days of stereolithography and selective laser sintering, we owe a debt of gratitude to the early pioneers of 3D printing who helped set the stage for the incredible advancements we see today.
The Industrialization of 3D Printing
3D printing may seem like a futuristic concept, but it has actually been around for decades. In fact, the first patent for 3D printing was granted in the 1980s to Dr. Chuck Hull, the co-founder of 3D Systems Corporation.

The industrialization of 3D printing refers to the process of using this technology to mass-produce consumer goods and other products. The idea is simple: instead of relying on traditional manufacturing processes, which can be time-consuming, expensive, and wasteful, companies can use 3D printing to quickly and efficiently print products on demand.
One of the most significant developments in the industrialization of 3D printing has been the emergence of additive manufacturing (AM) technologies. Unlike traditional manufacturing processes, which involve subtractive methods (cutting, drilling, etc.), AM is an additive process that builds up products layer by layer, using materials like plastics, metals, and ceramics.
One major player in the industrialization of 3D printing is General Electric (GE), which has invested heavily in AM over the years. In 2016, for example, GE announced plans to 3D print more than 100,000 fuel nozzles for its LEAP jet engine each year, which could save the company millions of dollars in production costs. GE has also used 3D printing to create lightweight parts for its GE9X aircraft engine, which could improve fuel efficiency and reduce emissions.
Another area where 3D printing has been heavily industrialized is in healthcare. 3D printing has revolutionized the way medical devices are made, allowing for personalized and customized implants and prosthetics. For example, surgeons can now create 3D-printed models of their patients’ organs or bones, which can allow them to practice surgeries before operating on the actual patient. 3D printing has also been used to create hearing aids, dental implants, and even pharmaceuticals.
One company making significant strides in the industrialization of 3D printing in healthcare is Stratasys, which has developed a 3D printer that can create complex medical models and devices. The company has also partnered with leading medical firms to create 3D-printed surgical guides and implantable medical devices.
Finally, the automotive industry has also begun to embrace 3D printing, using it to print everything from engine parts to car bodies. For example, Local Motors, a Phoenix-based automaker, has used 3D printing to create the Strati, a two-seater electric car made with just 49 parts, all of which were 3D-printed. By using 3D printing, Local Motors was able to reduce the time it took to create the car from months to just weeks.
Overall, the industrialization of 3D printing has been a game-changer for many industries, enabling companies to produce products more quickly, efficiently, and economically than ever before. As the technology continues to evolve and improve, it’s likely that we’ll see even more innovative uses of 3D printing in the years to come.
