Building a Plastic 3D Printed Engine - junk idea or possible?
NickG:
Chris,
I was going to suggest the printed engine!! If it works you could rattle a few sets out and sell on ebay! Can't wait to see...

David Jupp:
Parts printed to be assembled later, or printed as a (near) complete assembly?
NickG:
Oh yeah, didn't think of doing it as an assembly, didn't think that type of thing was possible until I saw that bearing! Guess you could so lots as long as you were prepared to do a certain amount of finishing off though? You mentioned not being able to do a wobbler or slide valve but is that because of the way it's built up or just because you intended on being able to assemble immediately? If you tried top lap a valve with a printed part would it give a smooth finish?
raynerd:
No no no! I never intended to print a full assembled engine!!! No, just parts and put it together. I thought a wobbler won`t be possible because of the poor surface finish on flat parts. That being said, typical me in that I`ve said something and not tried it! It might just be worth me printing off two blocks of plastic and trying to lap them flat together and see if it can be done. If it can, a simple wobbler might be the way forward.
My problem is the drawing...I`m so slow!! I`m definately going to give this a go.
Chris
:update: On my thrird attempt at a bearing and I`m half way through and it is looking ok!!!

Chris have you seen the engines on thingiverse ?
