This is a qualitative leap in 3D printing technology, and this change has only gradually occurred in the last two years. In 2011, the use of 3D printing metal for titanium alloy and stainless steel materials enabled Boeing to directly print aircraft wings with this technology. Of course, the size and price of this printer are on another level.

3D printers are limited by 3D printing filament, and the initial application of 3D printing is mainly limited to sample making. When auto parts manufacturers or dentists complete a product design, they often need to use a 3D printer to print out the designed product within a few hours, modify it repeatedly and then put it into a large-scale production line. Compared with traditional model making, the production method greatly saves time and material costs.

At present, Objet alone can use 14 basic materials and mix and match 107 kinds of Desktop 3D Printing Filament  materials on this basis. The mixing and matching and coloring of two materials are also a reality. The price of these materials is as cheap as several hundred yuan (RMB) per kilogram, and the most expensive is about 40,000 yuan.
