![]() ![]() In 2002 it was possible to print a fully functional kidney in 3D. In particular, a synthetic coating (from the patient’s own cells) could be used to implement solutions to problems in certain organs, such as a bladder. In 1999 it was already being used in medicine. Expansion and diversification of 3D printingģD printing had been given the starting shot and was being experimented with in all sorts of areas. One of these machines, working “alone” for an entire night, could have a rather complex piece ready the next morning. In 1992, and with the help of 3D Systems, the first SLA or stereolithographic printers appeared on the market.Īlthough with imperfections, it was already possible to create an object layer by layer, with a three-dimensional shape.Īn ultraviolet ray solidified a type of photopolymer (viscous liquid) and thus built the object, superimposing layers on top of others according to the 3D design submitted. The first commercial 3D printing machines In addition, the STL file format was born, which today is the most used by all 3D printing software.Īlready in the 1980s other researchers were making popular alternative methods, such as Beaman and Deckard and their selective laser sintering, or the company Stratasys, which patented molten deposition modeling and a decade later acquired the Polyjet Photopolymer technology. It was revolutionary since it was now possible to test and see how the printed object would look in a very approximate way, without having to spend time, resources and materials on testing.ĭo you think 3D printers have changed much since 1984? Not at all! Here you can see the diagrams presented by Charles Hull in his original patent and what a Form 2 stereolithography printer looks like today. In other words, it makes it possible to create a 3D model from a simple image. This is the technique that makes it possible to create a 3D object from digital data (nothing but zeros and ones). The first 3D printing patent, filed by Charles Hull in 1984 and approved in 1986 ![]()
