So, my school has 6 3D printers and engineering students are allowed to print basically anything they want within reason, so long as it's for a project. Sadly, this isn't a plane I've built in SP, it's one that I modeled in Autodesk Inventor, a 3D modeling program. I still have to cut off the supports on the wings that it printed, and also reattach a stabilizer that didn't print properly for whatever reason. Either way, it turned out pretty well.
