"Swipe", accompanied by a slight printing sound, within a few minutes, an exquisite plastic three-dimensional avatar model was produced on the printer! On February 27, our province's first self-developed and manufactured 3D printer met with the media at the Hefei University of Technology 3D printing and laser remanufacturing center, and demonstrated a variety of three-dimensional models on the spot.
This 3D printer is slightly taller than traditional printers. A printing pen ejecting printing materials is suspended at the upper end. There is an operating table at the bottom. The middle is free to carry the printed objects. When working, the printing pen rotates from bottom to top and 360 ° according to the set program, and the material is ejected at a uniform speed to complete the printing. Yuan Zijun, one of the inventors of this technology and the director of the 3D printing and laser remanufacturing center of the Polytechnic University, explained that 3D printing is actually the reverse process of tomography. Tomography is to "cut" something into countless superimposed pieces. 3D Printing is printing piece by piece, and then superimposed together to become a three-dimensional object. The biggest difference from a traditional printer is that the "ink" it uses is a real raw material. At present, the technology they master can realize the printing of engineering plastic parts, metal castings and glass parts.
Compared with the traditional manufacturing process, 3D printing can save a lot of raw materials and produce high-precision parts. From the perspective of the world, the earliest 3D printing appeared in the 1980s, but it has been put into civilian use in recent years. It is mostly used in large-scale manufacturing, such as: the aircraft produced by the US Boeing Company, 10% of the parts are like this. " Print it out. The biggest feature of this 3D printer independently developed and manufactured in our province is that it is designed for individuals, paving the way for entering the home. "After realizing home use, as long as you can think of things, as long as the materials allow, you can quickly print them out, such as toys, slippers, keys, etc., that will take us into a wonderful world of manual self-help." Professor Yuan said, this kind of A 3D printer with pure "Anhui blood" will be able to enter the home market as soon as this year, and the price is expected to be more than 1,000 yuan.
