The 3D printer (3D printers) abbreviation (3DP), a magical printer designed by an inventor named Enrico Dini (Enrico Dini), is not only able to "print" a complete building, but can even print an astronaut the shape of any desired item in a spaceship.
3D printer is also called a three-dimensional printer (3DP), is a kind of cumulative manufacturing technology, rapid prototyping technology, a machine, it is a digital model file based on the use of special wax, powder metal or plastic and other fusible materials, by printing a layer of adhesive material to create three-dimensional objects.
The principle of 3D printer is to put the data and raw materials into the 3D printer, the machine will be in accordance with the program to create a layer of product. 3D Printer The biggest difference between a 3D printer and a traditional printer is that it uses "ink" as a solid raw material, with a wide variety of layers, which can be used to print a variety of media, from a wide variety of plastics to metals, ceramics and rubber.
1, "Inkjet" way. Use a printer nozzle to spray a thin layer of liquid plastic onto the mold tray, which is then disposed under ultraviolet light, and then the die tray drops a tiny distance for the next stack.
2, "melt molding" technology, the whole process is to melt plastic in the nozzle, and then through the deposition of plastic fibers in the form of thin layer.
3, "Laser sintering" technology, powder particles as the printing medium, powder particles sprayed on the mold tray to form a very thin layer of powder, casting into the specified shape, and then by the spray liquid adhesive for curing.
4, some are the use of electronic flow in the vacuum melting powder particles, 3D Printer when encountering complex structures such as holes and cantilever, it is necessary to add gels or other materials to provide support or to occupy space, the powder will not be cast, and finally only water or air flow to wash off the support can form pores.
