Let’s delve into the history of this groundbreaking technology and explore the key moments and figures that shaped its evolution.
The Genesis of 3D Printing: Early Inventions (1980s)
The 1980s marked the true birth of 3D printing, with several pioneers independently developing technologies that laid the foundation for what we know today. These early inventors were driven by the desire to create faster and more efficient prototyping methods, moving away from traditional subtractive manufacturing processes.
Dr. Hideo Kodama’s Early Rapid Prototyping
One of the earliest forays into 3D printing came in 1981 with Dr. Hideo Kodama in Japan. He is credited with inventing one of the first rapid prototyping systems. Dr. Kodama’s approach involved a layer-by-layer manufacturing technique using a photosensitive resin that solidified when exposed to UV light. While his work didn’t immediately achieve commercial success due to patenting challenges, it was a crucial early step, demonstrating the potential of additive layer manufacturing. He developed a system remarkably similar to stereolithography, highlighting the parallel inventive spirit of the time.
Chuck Hull and Stereolithography (SLA) – “Inventor of 3D Printing”

Often hailed as the “inventor of 3D printing,” Chuck Hull made a significant breakthrough in 1986. He filed the first patent for stereolithography (SLA), a technology that uses UV lasers to cure liquid resin, layer by layer, into solid objects. Hull didn’t just invent the process; he also commercialized it. Crucially, he developed the .stl file format, which remains the standard file type for 3D printing to this day. His company, 3D Systems Corporation, released the SLA-1 3D printer in 1989, marking the arrival of the first commercially available 3D printing system. Hull’s contributions were pivotal in establishing 3D printing as a viable technology and setting the stage for its future growth.
Carl Deckard and Selective Laser Sintering (SLS)
In 1988, Carl Deckard, then a student at the University of Texas, developed and licensed selective laser sintering (SLS) technology. SLS is another form of 3D printing, but instead of liquid resin, it uses a laser to fuse powdered materials – such as plastics, ceramics, or metals – together layer by layer. This opened up possibilities for using a wider range of materials in additive manufacturing. Deckard’s invention broadened the scope of 3D printing beyond photopolymers and demonstrated the versatility of layer-based manufacturing.
Scott Crump and Fused Deposition Modeling (FDM)
Adding another key technology to the 3D printing landscape, Scott Crump patented Fused Deposition Modeling (FDM) in 1989. Also known as Fused Filament Fabrication (FFF), FDM involves extruding a thermoplastic filament layer by layer to build a 3D object. Crump co-founded Stratasys, which became a leading company in the 3D printing industry. FDM technology is known for its accessibility and affordability, making it one of the most widely used 3D printing methods, especially in desktop 3D printers.
Growth and Commercialization in the 1990s
The 1990s witnessed the early 3D printing industry taking shape. New companies emerged, and research and development continued to explore and refine additive manufacturing technologies. While the technologies existed, the widespread commercial availability and adoption were still in their nascent stages. It was a decade of building the foundation for future expansion, with companies like 3D Systems and Stratasys leading the way in developing and marketing these innovative systems primarily for industrial prototyping applications. The focus was on demonstrating the value proposition of rapid prototyping to various industries, highlighting the time and cost savings compared to traditional methods. The decade laid the groundwork for the more accessible and diverse 3D printing landscape that would emerge in the 21st century.
The RepRap Revolution: Open Source 3D Printing (2000s)
The early 2000s brought a significant shift in the 3D printing narrative, marked by the rise of open-source initiatives. This era democratized the technology and paved the way for wider accessibility and innovation.
The RepRap Project and Self-Replication

2005 was a pivotal year with the launch of the RepRap Project, spearheaded by Dr. Adrian Bowyer. RepRap, short for Replicating Rapid Prototyper, aimed to create a low-cost, open-source 3D printer capable of self-replication. The RepRap printer was designed to print many of its own plastic parts, allowing users to create copies of the printer itself. This groundbreaking concept significantly lowered the barrier to entry for 3D printing, making it accessible to hobbyists, researchers, and small businesses. The RepRap project became a catalyst for the desktop 3D printing movement and inspired countless innovations in the field.
Open Source and the Rise of Makerbot & Ultimaker
The open-source nature of the RepRap project had a profound impact. As the patents for FDM technology began to expire around 2006, the RepRap project’s influence fueled a surge of new 3D printer manufacturers. Makerbot, founded in 2009, was a prominent example. Makerbot focused on bringing 3D printing to a broader audience, offering DIY kits that enabled users to build their own affordable 3D printers. Their online platform, Thingiverse, became a central hub for the 3D printing community, hosting a vast library of free and paid 3D printable designs.
Around the same time, in 2011, Ultimaker emerged from the Protospace FabLab in the Netherlands. Inspired by the RepRap project, Ultimaker’s founders sought to create a more user-friendly and reliable 3D printer, moving beyond DIY kits to offer a complete ecosystem of hardware, software, and materials. Both Makerbot and Ultimaker played crucial roles in popularizing desktop 3D printing and expanding its reach beyond industrial applications into homes, schools, and maker spaces.
