RepRap 3D Printer Plotting Test

Today, I would like to introduce you to a 3D printer I am building. 3D printers are undoubtedly amazing machines, and the open-source movement has certainly left no stone unturned when it comes to these rapid prototyping ones. After having almost completed this printer, I have identified several shortcomings in its design, and am currently designing my own printer to share with the world – “innovation through iteration”, as I always say.

This is a perfect project for kids wanting to clinch a science fair ribbon too. Wow the judges by using a laser pointer to transmit your favorite song from across the hall! I ran
