It all began in 1984. Charles Hull—the alleged father and inventor of the technology came out with the idea of 3d printing during working with the UV light. Later on, more and more scientists found the concept appealing. After the foundation of 3D Systems by Hull, the technology has begun to be continuously and rapidly developed. This finally led to a whole new field of science—stereolitography.
Today, this kind of printing is sneaking into all possible aspects of human life. The fields of usage vary from medicine to spacecraft construction, from kitchen accessories to dentures alongside architecture and security mechanisms. The only limit is your imagination, as the printer adjusts to any design or sketch. What are the mechanisms?
Different types for different hypes
So many possibilities are linked to many different kinds of 3d printing. One of them is FDM (Fuse Deposition Modelling), that processes and melts plastic—the main material and source of future products. It’s main advantage is a great range items’ sizes. Additionally, they are more resistant to damage. Another method is SLA (Stereolitography). This one, on the other hand, involves photopolymerization, a process that relies on connecting molecules with a beam of light. Here, the main assets are precision and high quality. Next technique is SLS (Selective Laser Sintering). This one is most popular and is used most often, as the price of products is closely related to their quality. The material used in SLS is powder processed by a special laser sintering printer. There are also sls nylon printers. After the process, the final product’s main assets is resistance to damage and long lifetime.
How it is used?
With 3D printing makes it is possible to create objects of any kind, shape and size. Moreover, it is possible to reshape items already printed. As this technology is being more and more efficient, products of 3D printing are used in industry, medicine and stomatology, advertising, space exploration, architecture, army, even fashion along with shoe industry.
Item that are useful, new and needed are air pollution masks and exoskeletons. The first ones can protect both adults and children from air pollution. Considering the contamination that is beginning to be more and more threatening, this solution is more and more appealing. The exoskeleton is a solution in a different field. It helps children with many bone and body disorders to function fully in everyday life.
