Radial engine printable

cults3d

As I recently acquired an FDM printer, I decided to print my radial engine design from 12 years ago. To make it work seamlessly, I re-designed it and hope you'll like the result. All parts were printed with support material except for the cylinder assembly, which was printed without support but with a brim. For added strength, the crankshaft and winch were printed at 100% infill - I had to test them multiple times as they did break apart during testing. Please take a look at the images to see how the engine is assembled in sequence. Before assembling the parts together, make sure everything moves smoothly. Depending on your printer's capabilities, you may need to grind the inner surfaces of the cylinder parts and piston edges. The holes are 2mm in diameter; I drilled each one after printing. Additionally, it might be necessary to shorten the pushrod covers slightly. To assemble the engine, I used CA glue - be cautious not to apply too much as it can cause issues. If you've assembled all the parts correctly, you'll have a remarkable little model engine that everyone will want to crank.
