Check Out the Collapsible, Compact Flatpack 3D Printer

Reddit user Eponra has posted the details of their Flatpack 3D printer on GitHub. You can make this fixed bed cantilever foldable printer with easy-to-source parts.

Eponra assures makers that all parts are off-the-shelf, meaning it’s easy to assemble and source for DIY enthusiasts.

Once folded, the printer can fit into a spool box (220x210x75mm), making it entirely small enough to carry around. It can print in a respectable 120x 114 x 114 mm build volume when unfolded and set up.

The design has a fixed bed, with a cantilever-mounted print head moving in all axes. It can print at temperatures up to 300°C if using Eponra’s suggested Mellow Copper NF Smart 500°C. This hot end uses an Ender/CR-10 style mount, so we surmise it could use a large number of hot ends.

The printer can be powered using a 150W external power brick.

For safety reasons, Eponra chose a DC-powered print bed but stated the design could also use an AC bed, which would mean quicker heating but a trickier, less accessible build for DIY novices.

The design is entirely open source and available on GitHub. Eponra credits apsu for coming up with the idea to use a fixed bed cantilever on the 3D Printing discord #reprap-and-custombuilds channel, where designers can find plenty of inspiration and conversation about custom builds like the Flatpack.
