Operation of a 3D printer
Below are 4 steps that explain 3D printing process.
Step I: (CAD)(3) file is developed by using a model program that is done either from the beginning or scratching of the 3D model that is produced by the 3D scanner. By use of either of the format, a file is generated to be sent to the 3D printer. While undergoing the process, the software slices the design into thousands of horizontal layers. The layers are arranged horizontally on top of the other until the 3D printable object is delivered. Examples of software that are used for 3D designs are AutoCAD and Solidworks, given they have a steep learning curve and are easy to learn. Also, Google SketchUp is popularly used, and the Blender program preferred for advanced features.
Step II: (motoring) the 3D printer the motoring is required to have high accuracy and low torque for proper functionality. The steeper motor is preferred for its ability to convert digital pulses to mechanical shaft rotations. The preference to use step motors is they are highly dependable, low costs, high torque at very low speeds, and they are considered to be simple in their operations. It is possible to possible that a fraction of degree is done by use of gears to move the printer head of its specific displacement. Four stepper motors are in the 3D printer, which is designed for particular functions. Three of the motors move in X, Y, X direction of the printer head while the forth one rests on the plate bed.
Step III: (processing stage) All the AM335x microprocessors are identified to have an enhancement in industrial interface options, better imagery, and excellent graphic processing. The device can produce great results with the embedded high-level operating systems (HLOSs). Some subsystems are present in AM335x microprocessor. First, Graphic Accelerator subsystem for all the 3D graphics to enhance the display and allows independent operations and clocking services for flexibility and efficiency plus upgraded speeds of 600MHz to more significant than 1GHz. The second subsystem is the Microprocessing unit (MPU).
Step IV: (MOSFET drive) MOSFET drive is fitted on to the bipolar stepper motor that allows the engine to have the capability to move in all directions. Given the stepper motor can open to a loop system, provision of high accuracy to facilitate printing in specific places. Thus, MOSFET is preferred for its fast frequency operations.
