When we think 3D printers, we most commonly think of the fused-deposition modelling type that squirts molten plastic out of a hot nozzle. Typically, these are tabletop units designed to be set up and used in a workshop environment. [BingoFishy] dared to think outside the box however, and whipped up a compact, portable 3D printer for working out on the road.

The printer is almost entirely self-contained, running an OctoPrint controller with built-in hotspot which allows print files to be sent to the unit over a smartphone. The motion platform is built out of DVD drive stepper motors and rails, with dual motors used on the Z-axis to ensure there’s enough torque to move smoothly. Power is courtesy of 26650 cells, in a 2S3P configuration, which provides 3 hours of runtime. While this might not sound like much, for a compact printer with a small build volume, it’s a […]
