3D printed mechanical Clock with Anchor Escapement

pinshape

This innovative mechanical clock showcases that 3D printing is not just for aesthetics, but also for creating functional and intelligent devices. It features an anchor escapement and a balance wheel with a spiral spring, displaying seconds, minutes, and hours in real-time. The winding mechanism incorporates a nested planetary gear, allowing the clock to continue running while being wound up. Every component of the clock is 3D printed, except for a few small screws, metal pins, the cord, and the lead for the weight. This video demonstrates the clock's functionality and the building process, which can be viewed here: http://youtu.be/HgZBPYJ2Y-w The design was created using Blender and printed with a Rapman 3.2 in PLA material. To ensure proper fitment of certain parts, a loose clearance is required for components such as the hollow shaft for hours and minutes, while other parts like the hands need a press fit. The 3D files are optimized for older printers with inaccuracies in the xy-axis or a poorly guided z-axis. To compensate for this, overextrusion can be used, and Simplify3d offers an additional parameter: "process settings / advanced / other / horizontal size compensation". Pins: * 1 x Balance wheel: 1.5mm diameter, 40mm length * 1 x Escape wheel: 2.0mm diameter, 28mm length * 1 x Reduction gears: 2.0mm diameter, 60mm length * 1 x Drum Transmission: 3.0mm diameter, 60mm length * 1 x Drum Axis: 3.0mm diameter, 60mm length * 1 x Crank transmission: 3.0mm diameter, 30mm length * 4 x Planets Axis: 3.0mm diameter, 39mm length * 1 x Weight Axis: 3.0mm diameter, 15mm length Screws: * 6 x Frame: M3, 12mm, Flat Head * 5 x Winding Drum: M3, 10mm, Flat Head There are multiple STL versions of the winding mechanism available, each with a different combination of revolutions per hour and weight movement: a) Simple Ratchet v1: 4.22 revolutions per hour (weight moves 26.5cm/h) b) Simple Ratchet v2: 2.25 revolutions per hour (weight moves 14.1cm/h) c) Planetary Drum v1: 3.01 revolutions per hour (weight moves 18.9cm/h) d) Planetary Drum v2: 1.61 revolutions per hour (weight moves 10.1cm/h) The clock functions well with version c and a 1.2kg weight, but for version d, a weight of approximately 2.3kg may be required due to varying friction levels within the system.
