How to Make a Fully Mobile 3D Printer Powered by Trash

🔌By repurposing a motor from an old pressure washer and a treadmill, you can generate electricity by manually spinning the motor, powering the 3D printer.

♻️The project emphasizes the use of recycled and discarded materials found in garages and workshops, reducing waste and promoting sustainability.

⚙️To regulate the engine speed based on the printer's operation, the throttle is adjusted to increase or decrease RPM, ensuring stable power supply.

🔧The project involves trial and error to determine the right pulley sizes and gear ratios to match the motor speed with the desired voltage output.

📶A capacitor is used to smooth out current fluctuations, ensuring a more stable voltage supply to the 3D printer and preventing power interruptions.

Can I use any type of motor for this project?

—It is recommended to use motors that generate electricity when spun manually, such as those found in pressure washers or treadmills.

Are the materials used easy to find?

—Yes, the project focuses on using recycled and discarded materials commonly found in garages and workshops, making them easily accessible.

How do you ensure a stable power supply to the 3D printer?

—The engine's speed is regulated by adjusting the throttle, allowing for increased or decreased RPM to match the printer's power requirements.

What if the voltage output is too high or too low for the 3D printer?

—The project involves adjusting the pulley sizes and gear ratios to match the motor speed with the desired voltage output, ensuring compatibility.

What role does the capacitor play in the project?

—The capacitor is used to smooth out current fluctuations, providing a more stable voltage supply to prevent power interruptions during 3D printing.
