Project 7: Arduino-Based 3D Printer

Problem Statement

Commercial 3D printers are expensive and not accessible to schools, small labs, or hobbyists in developing regions. There's a need for an affordable, open-source, and educational alternative for rapid prototyping.

Description

This 3D printer is built using an Arduino Mega with a RAMPS 1.4 shield, stepper motors, limit switches, a heated bed, and an extruder. It uses G-code to print objects layer by layer. Open-source firmware like Marlin is uploaded to the Arduino. STL files are sliced using Cura or PrusaSlicer. The frame can be built from aluminum, wood, or 3D-printed parts.

Applications

• Rapid prototyping of mechanical parts
• Educational demonstrations in STEM
• Biomedical modeling (e.g., prosthetics, anatomical models)
• Creating customized enclosures for electronics
• Manufacturing spare parts in remote areas
• Innovation hubs and maker spaces
• Student projects and hands-on learning
