SLS printing – a printing revolution?

More and more often do we hear about 3D technology. It is conquering  the market, our homes and the world. What is it then and what does it offer? 3D printing, invented by Charles Hull in 1984, is without a doubt an innovative and prospective solution to printing as it can create any size and any shape objects incredibly fast. Used in many fields and areas, for example medicine, space travels, home management and building, architecture and security mechanisms. How does it work then?

What are the options?

There are many kinds of methods used in 3d printing. One of them is FDM (Fuse Deposition Modelling), that in the process uses melted plastic. The leading advantage of this technique is the possibility of creating objects of any size, that additionally are immune to damage.  Different method is SLA (Stereolitography). This type, on the other hand,  is based on a process of photopolymerization. This process relies on linking molecules by treating them with a beam of light. SLA’s main advantage is that it is very precise and operates with high quality, which result in high quality products. Another technique is SLS—Selective Laser Sintering. This one is most popular and is used most often, as it is the most cost-effective of the methods. The component that sls 3d printer uses is powder. The material is sintered by a laser. In the process, the pilot product is very resistant and have a long endurance.

What is the final effect?

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. Items that are useful, new and needed are air pollution masks and exoskeletons. The first ones can protect both adults and children from air pollution. The exoskeleton is a solution that helps disabled people, for example, who suffer from SMA (Spinal Muscular Atrophy) to function with full capability.

The limits of the kind of the product is only human’s imagination. You can create shoes, glasses, components of space ships and a lot more. 3D printing is used in everyday life, and it is reassuring that is highly developed every day, being more and more available for everyone. Soon enough, 3d printers will be present in every house in every corner of the world.
