High School Student Designs a Portable Battery-Operated 3D Printer

The vast majority of 3D printers today use a process called fused filament fabrication (FFF). They accept thermoplastic in the type of a thin hair of filament, which is melted and after that transferred onto the print bed in succeeding layers to make the desired part. Between the motors, fans, hot end, and heated bed, FFF 3D printers can take in quite a lot of power. That could be anywhere from about 50 W to numerous hundred watts, and peaks much greater than typical while the bed and hot end are warming up. That makes it difficult to power them from a battery, but this high school student had the ability to create a tiny 3D printer that is portable and battery-operated.

Redditor BingoFishy is a high school trainee and created and built this small 3D printer for a summer season project. That’s exceptionally outstanding when you see how professional-looking this 3D printer is. It looks as excellent or much better than most of the 3D printers you will discover on the marketplace today. This isn’t simply a lesson in great industrial design, due to the fact that this printer is entirely practical and handles to achieve a task that we sanctuary is seen before. The entire printer is approximately the size of a gallon container of milk and can printing continually for about three hours from the integrated battery. Yes, the build area is really little at just 50 x 50 x 46 mm (1.97 x 1.97 x 1.81 inches), however, that’s still enough to print numerous helpful things.

While the style of the printer is entirely custom, it was constructed using mostly off-the-shelf parts. The stepper motors and direct rods for each axis were salvaged from DVD drives. The X and Y axis each have a single stepper motor, while the Z axis has two. Those are controlled by a SKR 1.4 DIP control board, which is the same board utilized in the Creality Ender. This is coupled with a Raspberry Pi and OctoPrint, so BingoFishy can operate the 3D printer utilizing a smart device without the requirement to connect a computer. Extrusion is handled by a Creality all-metal hot end with a MK8 extruder upgrade. Power originates from a set of six 26650 lithium ion batteries, each with a capacity of 5300mAh, wired in 2P3S set up with a battery management system board. The battery level indicator is an inexpensive 3S touch sensing unit module. The print volume might be limited, however, we believe this small 3D printer would be best for a Maker Faire or other hacking occasion.
