LOCOmotive

The LOCOmotive was inspired by the 1876 Exhibition steam locomotive. After initial research, I found several reference images of the locomotive's exterior; however, details of the internal components were scarce. To bridge the gap, I extended my research to better-documented locomotives from the same era, such as the Jupiter and The General.
As I was unfamiliar with steam locomotive mechanics, I dedicated time to studying the engineering principles behind them. I then adapted the design to a smaller, functional scale, taking into account the absence of actual steam power. This required reinterpreting key components while preserving mechanical authenticity.
The model was 3D printed using a MakerBot Method printer. PLA was used as the primary material, with dissolvable PVA filament for support structures, allowing for clean, precise prints of complex assemblies.
The final product consists of approximately 90 individual parts, most of which interlock without the need for adhesive. The assembly relies on precise tolerances, clasps, and custom connection mechanisms. The wheel assemblies and driving linkages are fully functional, replicating the motion of a real steam locomotive. The two rows of driving wheels are connected by a central linkage that terminates in an improvised piston, simulating the operation of a traditional steam engine.
