3D Printer using Arduino - Arduino Geek

By
Hello everyone! Welcome to Arduino Geek. Today we will discuss about an Arduino based 3D Printer. So let's get started.

3D Printer using Arduino:

We can make a 3D printer using an Arduino board. The Arduino board is programmed to control the movements of the printer's various components, such as the stepper motors, extruder, and heated bed.

By using an Arduino board, a 3D printer can be customized and controlled using open-source software, which allows for greater flexibility and experimentation with different types of printing materials and techniques. Additionally, using an Arduino board for a 3D printer can be more cost-effective than purchasing a pre-built 3D printer with a proprietary control system.

However, building a 3D printer using Arduino can be a complex process that requires knowledge of electronics, programming, and mechanical engineering. It may involve sourcing and assembling the various components, configuring the firmware settings, and calibrating the printer for optimal performance. Despite these challenges, building a 3D printer using Arduino can be a rewarding project that allows for greater customization and experimentation in the world of 3D printing.

Components:

To build a 3D printer using Arduino, you will need the following components:
  1. Arduino board (e.g., Arduino Uno)
  2. A 3D printer kit (e.g., Prusa i3)
  3. Stepper motor drivers (e.g., A4988)
  4. Stepper motors (e.g., NEMA 17)
  5. Endstop switches
  6. Hotend (e.g., E3D V6)
  7. Heated bed
  8. Power supply (e.g., 12V or 24V)
  9. Cooling fan(s)
  10. Filament (e.g., PLA, ABS)

How to make 3D Printer using Arduino:

Building a 3D printer using Arduino can be a challenging but rewarding project. Here are the basic steps to make a 3D printer using Arduino:

1. Choose the 3D printer design and gather the necessary components: 

There are various 3D printer designs available, such as the RepRap, Prusa i3, and Delta. Choose a design that suits your needs and budget, and gather the necessary components such as stepper motors, linear rails, hotend, heated bed, and an Arduino board.

2. Assemble the frame: 

Follow the instructions to assemble the frame of the 3D printer. This usually involves connecting the linear rails to the frame and assembling the 3D printer's structural components.

3. Install the stepper motors: 

The stepper motors are responsible for moving the print bed and the extruder. Install them in the designated locations on the frame and connect them to the motor drivers.

4. Install the hot end: 

The hotend is responsible for melting and extruding the filament. Install the hotend on the extruder carriage and connect it to the Arduino board.

5. Install the heated bed: 

The heated bed is responsible for keeping the print bed at a constant temperature. Install the heated bed and connect it to the power supply and the Arduino board.

6. Connect the electronics: 

Connect the motor drivers, endstop switches, and other electronics to the Arduino board according to the schematic diagram.

7. Flash the firmware: 

Flash the firmware onto the Arduino board. There are various firmware options available, such as Marlin and Repetier. Configure the firmware settings according to your printer's specifications.

8. Calibrate the printer: 

Use a calibration tool to calibrate the printer's bed leveling and nozzle height.

9. Test print: 

Load a 3D model into your 3D printer software and start a test print to ensure that your printer is functioning correctly.

Making a 3D printer using Arduino can be a complex process, but it is a great way to learn about 3D printing and electronics. With some patience and effort, you can create a custom 3D printer that meets your specific needs and budget.

Arduino Code:

The Arduino code for a 3D printer typically involves configuring the firmware settings and defining the motor movements for the printer. Here is an example code snippet for a 3D printer using Arduino:

#include <Stepper.h>
#define STEPS_PER_REVOLUTION 200
#define STEPS_PER_MM 50
#define MAX_FEEDRATE 500

Stepper x_stepper(STEPS_PER_REVOLUTION, 8, 9, 10, 11); // Initialize X-axis stepper motor
Stepper y_stepper(STEPS_PER_REVOLUTION, 4, 5, 6, 7); // Initialize Y-axis stepper motor
Stepper z_stepper(STEPS_PER_REVOLUTION, 2, 3, 4, 5); // Initialize Z-axis stepper motor

int x_dir = 1;
int y_dir = 1;
int z_dir = 1;

float x_pos = 0;
float y_pos = 0;
float z_pos = 0;

void setup() {
  x_stepper.setSpeed(MAX_FEEDRATE);
  y_stepper.setSpeed(MAX_FEEDRATE);
  z_stepper.setSpeed(MAX_FEEDRATE);
}

void loop() {
  // Move X-axis
  if (x_dir == 1) {
    x_stepper.step(STEPS_PER_MM);
    x_pos += 1;
  } else {
    x_stepper.step(-STEPS_PER_MM);
    x_pos -= 1;
  }

  // Move Y-axis
  if (y_dir == 1) {
    y_stepper.step(STEPS_PER_MM);
    y_pos += 1;
  } else {
    y_stepper.step(-STEPS_PER_MM);
    y_pos -= 1;
  }

  // Move Z-axis
  if (z_dir == 1) {
    z_stepper.step(STEPS_PER_MM);
    z_pos += 1;
  } else {
    z_stepper.step(-STEPS_PER_MM);
    z_pos -= 1;
  }
}

Arduino Code Description:

This code snippet defines the number of steps per revolution, steps per millimeter, and maximum feed rate for the stepper motors. It then initializes the stepper motors for each axis and sets their speeds. Finally, it moves the X, Y, and Z axes in the desired direction and increments their respective position variables.

This code is just a simple example and does not include other important features like homing, bed leveling, or temperature control. It is important to note that 3D printer firmware can be complex, so it's recommended to use an existing firmware such as Marlin or Repetier instead of writing your own code from scratch.
