How To Make 3D Printer at Home | Arduino Project

Introduction

This tutorial will guide you through the process of building a 3D printer at home using an Arduino kit and stepper motors. This DIY project is perfect for science fairs or college projects, allowing you to create any object using G-code files from your computer.

Step 1: Gather Required Materials

Before starting the assembly, ensure you have all the necessary components. Here’s what you will need:

• 3D Printer Arduino Kit
• Hot End
• Extruder
• Stepper Motors
• 12 Volt 10 Amp Power Supply
• PLA Filament
• Software:
  • Cura (for slicing models)
  • Xloader (for uploading code)
  • Pronterface (for printer control)

You can find links to purchase these materials in the video description.

Step 2: Assemble the Frame

1. Build the Base:

   • Start by assembling the base of the printer according to the instructions in your Arduino kit.
   • Ensure all parts are securely fastened.

2. Add Vertical Supports:

   • Attach the vertical supports to the corners of the base.
   • Check that they are perpendicular to the base.

3. Install the Bed:

   • Secure the print bed onto the frame.
   • Make sure it can move up and down smoothly.

Step 3: Install Stepper Motors

1. Attach Motors:

   • Mount the stepper motors to the designated positions on the frame.
   • Use screws to secure them tightly.

2. Connect Wiring:

   • Carefully connect the stepper motor wires to the control board as per the wiring diagram provided in your kit.

Step 4: Setup the Hot End and Extruder

1. Attach the Hot End:

   • Install the hot end onto the frame, ensuring it is positioned correctly for printing.

2. Connect the Extruder:

   • Connect the extruder to the hot end and ensure it is properly aligned.

Step 5: Power Supply and Wiring

1. Connect the Power Supply:

   • Connect the 12 Volt power supply to the control board and ensure all connections are secure.

2. Wire Management:

   • Organize the wiring to prevent tangling and ensure safe operation.

Step 6: Install Software

1. Download Software:

   • Install Cura, Xloader, and Pronterface on your computer.

2. Configure Settings:

   • Configure the printer settings in Cura according to your printer specifications.
   • Load the required firmware using Xloader.

3. Test the Connection:

   • Use Pronterface to connect to the printer and test its movement.

Step 7: Print a Test Object

1. Slice a Model:

   • Use Cura to slice a simple 3D model and generate a G-code file.

2. Upload G-code:

   • Load the G-code file into Pronterface.

3. Start Printing:

   • Begin the print and monitor the first layers to ensure everything is functioning correctly.
