History of 3D printing
Research into creating physical objects through layer-by-layer build-up began long before the term “3D printing” became popular. The idea seemed to come straight out of science fiction, but over time it has become a reality.
History of 3D Printing: From the First Prototypes
In the early 1980s, Chuck Hull, an engineer from the USA, patented stereolithography technology. This method allowed the creation of solid objects by polymerising photosensitive resins using an ultraviolet laser. Considered one of the first 3D printing methods, this process set a foundation for what was to come. In 1986, Hull founded 3D Systems and produced the world’s first commercial 3D printer, the SLA-1.
Over the following decade, scientists and engineers globally developed various other 3D printing methods, notably including fused-deposition modelling (FDM) and selective laser sintering (SLS).
The Evolution to Modern Industrial Machines
With time, 3D printing has evolved to be more sophisticated and precise. Originally mainly used for rapid prototyping, 3D printers now significantly contribute to part production in aviation, automobiles, medicine, and myriad other sectors.
Today’s 3D printers can handle diverse materials, ranging from plastic and rubber to metals and ceramics. The quality of prints has seen considerable enhancements, resulting in parts with impressive detail and durability, rivaling those produced by traditional manufacturing methods.
Furthermore, many industrial 3D printers come furnished with cutting-edge features such as multi-material printing, integrated quality control tools, and automated material feeding systems.
So, the history of 3D printing is a story of tireless research, innovation, and man’s quest to transform his world. From the first experiments in stereolithography to today’s industrial marvels of engineering, it is a story that continues to inspire us with new achievements.
