The Working Principle Of 3D Printer
Nov 13, 2017

3D printer called 3D printer, is an accumulation of manufacturing technology, a machine that is rapid prototyping technology, it is a digital model of a file, the use of special wax material, powdered metal or plastic material can be bonded by adhesive material printing layers to create 3D objects. At this stage, three dimensional printers are used to make products. The technique of constructing objects by layer by layer printing. The principle of 3D printer is to put data and raw materials into 3D printer, and the machine will make the product layer by layer according to the program.

There are various forms of stacked thin layers on 3D printers.  The difference with the traditional 3D printer is the largest printer which uses "ink" is real in the raw materials, stacked thin layer in the form of a variety, can be used to print media types varied, from the range of plastic to metal, ceramic and rubber material. Some printers can combine different mediums to make the print object hard and the other soft.

1, some 3D printers use "inkjet" mode. Using a printer nozzle, a very thin liquid plastic material is sprayed on the mold tray, and then the coating is treated under ultraviolet light. After that, the mold tray drops a very small distance for stacking on the next floor.

2, there is the use of a called "deposition forming technology, the whole process is melting in the spray nozzle plastic, followed by the deposition of the plastic fibers to form a thin layer.

3. Some systems use a technology called laser sintering to use powder particles as printing media. The powder particles are sprayed on the mold tray to form a very thin layer of powder, which is cast into a specified shape and then solidified with a liquid binder.

4, there is the use of electron flow melting powder particles in a vacuum, when the complex structure contains holes and cantilever that requires medium with gel or other substances to provide support or to occupy space. This part of the powder will not be fused, and eventually the pores can be formed only by washing the support with water or air.
