The History of 3D Printing
AI will be bigger than 3D printing. Although some feel that 3D printing did not live to its hype, evidence shows the contrary. 3D printing continues growing every year, and its potential remains tremendous. AI will have a similar trajectory, where reality may not meet initial expectations for a while, but the technology will continue growing and growing in the background.
The History of 3D Printing
The concept of 3D printing, also known as additive manufacturing, originated in the 1980s. The first working 3D printing technology was developed by Charles W. Hull, who invented a process called stereolithography.
In 1983, Charles Hull co-founded a company called 3D Systems Corporation and received a patent for stereolithography apparatus and method. Stereolithography involved using a computer-controlled laser to selectively solidify layers of a liquid polymer to build a three-dimensional object. This marked the beginning of the modern era of 3D printing.
Throughout the 1980s and 1990s, Hull and other researchers and companies continued to refine and develop various 3D printing technologies. These advancements included the introduction of new printing methods like selective laser sintering (SLS) and fused deposition modeling (FDM).
The term "3D printing" became widely used in the early 2000s, as the technology gained more attention and commercial viability. Since then, 3D printing has undergone significant growth, with improvements in printing speed, quality, and accessibility. It has expanded into a range of industries and applications, from rapid prototyping to custom manufacturing and even medical applications like bioprinting.
While the concept and early development of 3D printing can be traced back to the 1980s, it is important to note that the technology has since evolved and continues to advance, with ongoing innovations and new applications being discovered.

3D Developments as of September 2021
The 3D printing industry has experienced significant growth and advancements. Here are some notable developments and trends:
- Expansion of Applications: 3D printing has expanded beyond rapid prototyping and is being increasingly used for manufacturing end-use products across various industries. It has found applications in aerospace, automotive, healthcare, consumer goods, architecture, and more. The technology's versatility allows for complex geometries, customization, and cost-effective production in certain cases.
- Improved Technology and Materials: The quality, speed, and capabilities of 3D printers have improved over time. New printing technologies, such as selective laser sintering (SLS), digital light processing (DLP), and binder jetting, have emerged alongside traditional fused deposition modeling (FDM) printers. Materials available for 3D printing have also expanded, including metals, ceramics, composites, and biocompatible materials.
- Lower Costs and Accessibility: The cost of 3D printers and materials has decreased, making the technology more accessible to individuals, small businesses, and educational institutions. This accessibility has led to a growing maker culture and the democratization of manufacturing, allowing people to create prototypes or custom products on their own.
- Advancements in Bioprinting: The field of bioprinting, which involves the printing of living tissues and organs, has seen significant progress. Scientists have been able to print functional tissues, such as blood vessels and skin grafts, and are actively researching the potential for creating complex organs for transplantation.
- Sustainability and Circular Economy: 3D printing has the potential to reduce waste and promote sustainable manufacturing practices. By enabling localized production and on-demand manufacturing, it can reduce transportation emissions and minimize excess inventory. Furthermore, 3D printing allows for designs that optimize material usage, reducing material waste.
