Titanic's Engine

cults3d

This is a historically accurate model of the Titanic's starboard triple expansion steam engine. When fully assembled, it is approximately 550 grams heavy, 25 cm long and 15cm high. This translates to a scale of roughly 75:1. All the cylinders, valves and the crankshaft are able to turn over. Plus, if you use the right kind of PLA and put a lot of extra effort into the model, you can run it with pressurized air.

This is by far my most complex and complicated project that I ever started. But now that it is complete, I am quite proud to share it with the world. **Warning: This is by no means an easy to print or easy to assemble model. You need a perfectly calibrated 3D printer, perfect bed adhesion, lots of experience with your slicer and at least a week or two of time to make everything run smoothly. Every single part needs to be manually sanded, adjusted or glued in some way or another. Also note that it took me one entire week to complete a single engine, after all the files were final! If this sounds like too much work, please consider not purchasing this model. Warning Warning: The complete engine exports are not printable with any technology I know. They are included for reference only. Also I never attempted to print the portside (left side) engine and the seperated parts are not included in this download. Please only attempt to print the files in the zip archive! Update 06 2023 I added a few files here that I needed for my 200% build seen in this video: https://www.youtube.com/watch?v=ZOpecbVx1Ww The ball bearing eccentric disc The ships screw The vacuum cleaner to exhaust pressure regulator If you want to build this larger model yourself, just use all the regular files and scale them up to 200%. All the nuts and bolts then become M4 instead of M2. For the ball bearing eccentric discs, you additionally need 80 steel ball bearing balls that have a 4mm diameter. Happy printing
