A Brief History of 3D Printing

7 Mins read

The revolutionary 3D Printing technology is rapidly spreading across the world and being adopted across sectors. But where did this technology come from and how did it came to be?

Read to know more about the glorious history of 3D Printing as it went from its first technology (Stereolithography) to a stream of technologies, printing a wide range of materials, used in innumerable applications and impacting the global manufacturing sector.

Late 1970s to End of 1980s

When we talk about the history of 3D printing  we will have to start from the late 1970s, even before the first technology – Stereolithography – was invented. The technology is older than you think. It may seem a fairly new technology but it is not. The birth of 3D printing can be traced back to late 1970s when the first inkjet printer was manufactured. The technology generated quite a buzz but nothing substantial could be achieved in the following half-decade.

In 1981, Dr. Hideo Kodama of Nagoya Municipal Industrial Research Institute, Japan, published a paper on Rapid Prototyping (RP) system. He imagined a system of printing layers of a model on a platform and building layer above layer to form the final product. He was to subsequently file for a patent but somehow Dr. Kodama could not do so and the application expired its one-year deadline. The RP system was in itself a great ideological breakthrough but with no practical use. The end piece of the jigsaw puzzle was still eluding many researchers.

Simultaneous to this effort by Dr. Kodama, a French researcher, Alain le Méhauté also got interested in the rapid prototyping system when he was working for Alcatel in early 80’s. He consulted with his colleagues about such a prototyping system but they were not interested in his ideas. But still determined to pursue his ideas, he shared his thoughts and ideas with Olivier de Witte who was working with a subsidiary or Alcatel at that moment. Olivier was quickly interested and his background in lasers meant that he knew of materials that could be cured/hardened on application of laser energy.

The two of them then brought their idea to Jean-Claude André who was working at the French National Center for Scientific Research (CNRS). On a personal front, Andre was interested in the idea but the CNRS rejected their proposal to fund.

The trio however still filed for a patent but sadly the had to abandon the project as their funding dried out.

Around the same time, in 1983, Charles Hull, an American Engineer, invented Stereolithography Apparatus (SLA) which also marked the year the first-ever part was 3D printed. He patented the technology in 1984 itself.

In 1986, Charles Hull was granted the patent and in the same year Co-founded 3D Systems, which is now one of the largest 3D Printing organizations. In the subsequent year, in 1987, the world’ first commercial 3D printer SLA-1 was launched.

Stereolithography is the first 3D printing process which was commercialized. The process involves namely four components:

1. A Laser beam – Source of Laser to solidify the resins
2. Elevator – For movement of Vat
3. Vat – It contains the material for creating the 3D product
4. Photopolymer Resins in liquid state – Material used in Stereolithography

The laser source flashes a Laser beam to solidify the semi-liquid Photopolymer resins. The Laser beam moves in X-Y axis across the surface of the resin. It moves across as per the 3D design of the model from the software. Once a layer of the resin is solidified, the elevator moves down lowering the Vat in the Z direction and now the laser traces the next layer. This process continues until the product is completely traced out. The elevator is now moved up to remove the product from the Vat.

In lay man’s language, we can say that the process is used to basically to slice a product into numerous layers and place those thin slices one over the other to form the final product.

The 3D product is created as the layers are formed one above the other. Due to the complex nature of the process, the products sometimes need support structures. These are mainly required for products with undercuts or overhangs. Like every process, this process too requires post-processing for removing the support structures and smoothening the walls. But comparatively the processing is far too less in Stereolithography.

Selective Laser Sintering

The second stage in the history of 3D printing brings us to the decade of the 90s. Stereolithography was the first 3D printing method which paved the way for the technology to grow and prosper. Although the technology was patented in 1984, it took another 6-8 years to build the first 3D Printer. In 1992, 3D Systems actually built an SLA Machine to present it to the world and let them see the power of 3D printing. By the same time, a start-up, DTM Corp invented the world’s first Selective Laser Sintering (SLS) Machine.

These machines were charting unexplored frontiers but still, a lot of years of research had to be put in it to make it commercially viable. These machines were slow to operate and still required some amount of manual intervention. The research went on until the 2000s.

History of 3D Printing

The third stage to understanding the history of 3D printing starts from the new century. Almost 20 years had passed since the first paper was published and technology was patented but still, the technology was in its infancy. This was the time for the technology to grow and showcase its true potential.

In 2000, a new breakthrough was achieved. First 3D printed organ was implanted in a human body. The scientists at the Wake Forest Institute for Regenerative Medicine, 3D printed the synthetic building blocks of human bladders. This newly generated tissue was then implanted in the human body.

This was the decade when the Bio-Printing took center stage and came up with exciting and prospective inventions. Scientists were eager to understand more and more about the technology and use it in the medical field due to its main feature of customization.

This was a golden period in the development of 3D printing in the medical application. Many start-ups started creating medical applications like printing a functional miniature kidney, building prosthetic limbs and other complex parts. Scientists even bio-printed the first blood vessels.

In 2005, the open-source movement took over and Dr. Adrian Bowyer’s RepRap Project launched an open-source initiative to manufacture a 3D Printer which could print many basic products. Its 2008 upgrade was a self-replicating printer. Suddenly, people everywhere had access to printers and they could print tangible products from just their ideas. The research was still going on and, in 2006; the first commercially viable SLS printer was manufactured and received widespread acceptance and demand from industries.

The creative innovations were effectively clubbed together by Shapeways, which was a marketplace where designers could display their designs and receive feedback on the same. Another company emerged in this technology boosting environment, MakerBot. They provided Do-It-Yourself open-source printers. This was the time when even regular designers could afford the 3D Printers to test their designs. The Entry barrier was breached and designers everywhere could now get their hands on this technology.

The current decade has been one of the most vibrant. It forms an important part of the history of 3D printing. As the days are passing by, the advances in 3D Printing are only following an upward trend and will continue to do so for the coming decade. 3D printers are available at most affordable rates and the accuracy is getting better with each iteration. This will continue year on year. The applications have crossed all limits which Charles Hull might have dreamt about. From plastic products to body organs, from automobile to aerospace, from manufacturing to jewelry and to the latest being Food Printing. We have also heard of 3D printed offices and 3D Printed cars and aircraft.
