Components of a 3D Printer and Steps to Work with 3d Printing

Here's how 3D printing works: CAD software is used to create 3-dimensional models, such as animal models, character models, parts models or miniature buildings, and so on. You can also use a ready-made model gallery. Then you copy them to the 3D printer with the help of an SD card or USB flash drive, set up the printer, and print them out.

    The working principle of 3D printers is basically the same as that of traditional printers, which are composed of control components, mechanical components, print heads, consumables and media. And the printing principle is the same. 3D printer key is the need to print before the computer designed a complete three-dimensional model, before the print output.

Components of a 3D printer

      Although FDM printers vary in size, material and role, they all basically have three different electromechanical systems. The role of these systems determines the results of your prints.

      Print head and extrusion system: The system responsible for heating and extruding the thermoplastic print material with the help of a nozzle to build the part. Factors such as nozzle size and extrusion speed affect whether the printer can print fine parts and how fast they can be printed.

      Hot bed and Z-motion system: The print head and extrusion system builds up the material onto the print bed. As parts are printed, the Z-motion system moves the bed in discrete, equal steps to build up each layer of the part. The accuracy of the motor driving the Z motion system controls the resolution and quality of the part as it is built in the Z direction.

      XY Gantry Motion System: The print gantry directly controls the X and Y operation of the print head. It is responsible for "making" the paths that create each layer. The strength of this frame and the quality of its motors and sensors interfere with the accuracy and precision of the parts on the same side of the hot bed.
