This is a compact and highly portable FDM printer designed to print small, high-resolution components. The entire frame (in yellow) can be 3D printed on a standard size printbed (220mm+). It is intended to be used in situations where a small size and high accuracy is needed. Because of the small size, the hotend is limited to around 220°C safe printing temperature. There is also no heated bed (yet), so PLA is the best bet for now.
The build process isn't too difficult, as long as you have a basic know-how of 3D printers you should be fine.
The frame size is 200x141x153mm. The build volume is 100 x 40 x 50mm. It is intended to be used with a 0.2mm nozzle.
It uses tiny NEMA 8 stepper motors to drive all 3 axes with ease because of the low-mass/inertia of the moving components. In fact, the Bowden tube's bend creates more resistance to the motors than the hotend carriage.
The complete BOM with pricing matrix is included. The current total build cost is **$135 USD** not incl
