Nowadays, desktop-class 3D printers come in a variety of different types on the market, but the basic working principle is the same.
Compared with other technologies, desktop 3D printers have the advantages of high speed, low price and high practicability. Understand the advantages of 3D printers, we also need to know how it works. A 3D printer is a device that can produce real three-dimensional objects. It uses layered processing and superposition forming, which is to create 3D solids by adding materials layer by layer, which is completely different from traditional material reduction technology. It is called a printer because its processing is similar to an inkjet printer.
As we all known, ink jet printers print flat images, and the printer head moves only in the x-axis direction and the y-axis direction to print a flat pattern. The 3D printer prints layer by layer in a three-dimensional space. After the X/Y axis prints a layer, the Z axis moves up a specified distance, and then starts the next layer of printing, eventually producing a three-dimensional model.
For desktop-grade 3D printers, the printhead is an important part of material extrusion. Because the printed solid object, the material needed, usually ABS or PLA wire. At present, the most commonly used FDM printer uses hot melt forming technology to extrude a strip of material in a nozzle part by melting at a temperature of about 200 degrees, attaching it to the bottom plate or the next layer of material and cooling and solidifying it. .
It’s working steps are like this: use modeling software to design the model, if you have ready-made models, such as animals, characters, or miniature buildings. Then copy it to the 3D printer through the SD card or USB USB stick. After the print settings, the printer can print them out. The working structure is exploded as follows. The 3D printer works in much the same way as a conventional printer. It consists of a control component, mechanical components, printheads, consumables, and media. The printing principle is the same.
