Building a 3D Printing Pen

Overview

Objectives/Goals My goal is to build a benchtop model which shows the concepts and mechanics of a 3D printing pen. Methods/Materials I first researched my topic and started to make my logic diagrams. Then, I bought my materials, including the Arduino Uno micro controller board, J-head hotend nozzle, 5 line 4 phase step motor, Kootek DC 5V 4 phase test module board, and relay. I practiced using the Arduino board with tutorials from the Vilsro manual. I created the individual circuits and programs by referring to online programs, which I modified for my use. I manufactured the phenolic board base. I attached the individual parts to my board and combined the programs and circuits. Results For my project I was able to research, build and design the necessary circuits and programs to create a benchtop model of a 3D printing pen. I was able to see how a relay, thermistor and motor circuit are all necessary to make a 3D printing pen work. Each of the circuits worked individually, however, I was not able to combine all the programs and make the model work in unison. I was able to combine the two programs without getting an error alert but, when tested the different circuits would not work together. Conclusions/Discussion I found that a motor, relay and thermistor circuit are all necessary components for building a 3D printing pen. I believe that with more time I can fix the programing bugs and get my benchtop model to work together. Also with specialized parts and some added components such as a portable battery package, this idea, with these circuits could become a safe, handheld, 3D printing pen.
