The student has become the teacher. A 3D pen turns into a 3D printer, Via Fabbaloo
YouTuber Tinkernut shows how to produce a “cheap 3D printer” in a recent video, but there’s an ironic twist to the plan.
One of the key objectives of anyone making their own 3D printer is to reduce cost, and that’s definitely the case here, where Tinkernut somehow builds a working 3D printer for USD$65.
But the process involves a bit of a cheat. Basically, the design involves reusing a cartesian motion platform previously designed by Tinkernut, costing USD$20, and combining that with a modified 3D pen.
A 3D pen? You remember, those handheld devices that include an extruder and hot end, and hopefully some safety features to keep you from burning your fingers and home. You gently move them around in 3D space to “print” 3D things. My opinion is that these devices are not really 3D printers by any definition. They are a hand tool used manually to make stuff, like a hammer or saw.
However, if you take them apart, they do include a rudimentary hot end and a motor to push plastic filament through it. Those are just the things you’d need to add to the motion platform to make a real 3D printer.
In the video here, you’ll see how the pen is essentially used as-is, with a simple modification to trigger it remotely from an arduino board controlling the cheap 3D printer:
