In this project I created a 3 piston engine using Inventor and added constaints to make it move accordingly. Next, I added legs and clearance on all mating parts so that it could be 3D printed successfully. The clearance allows for free movenment since this will all be printed as one part and if it wasn't there the parts would merge while printing. Afterward, I imported the Inventor iles into 3DS Max where I added material and rigged it to move all parts automatically when I rotated the crankshaft. Lastly, I rendered out the scene and edited it in Premiere.
