I finished this up last week and brought it with me to a model engineering show in Detroit where it attracted some interest. It has a few issues with the linkage but required amazingly little post-print finishing work.
Looks hudge. Are grey and black parts printed from Z-HIPS or Z-ABS?
Looks fantastic!!!
The parts were all printed with Z-ABS and mostly at 0.09 mm layer height. The bell housing looks almost cast from a few inches away.
dude!
We need some video footy of this thing in action!

These are from the original builder's Thingiverse pages:

My engine turned out pretty well, except that the block and head both had pretty badly warped bottoms, even one I tried in HIPS. Some of those parts take well over a day to print so it gets expensive in time and money to experiment with settings. None of the standard things suggested here helped me, though things did get better when I changed out the perf board.
The Zortrax-printed transmission got a fair amount of interest from attendees at the NAMES Model Engineering show in Detroit last weekend. Impressing those guys is tough because they build working model engines like this one:
