3D printed marble stirling

[aeropic]

Hi All,

Here is my last 3D printed stirling engine.
A kind of "useless machine" but quite fun to see running

All the instructions to build one are here:

Aviator, Darryl and Ian, thanks you for your feedback !
A bit tricky to make it run... As there is no pressure balancing system, once heated the midle position of the piston may vary from time to time. This is the reason why the wheel is mounted not glued on the carbon rod so that it's easy to modify its position .
If you've a 3D printer, try it, it's very easy to print

Cheers

Hi Alan,

That's a fun thing! Nice work!
I have a few questions.

I looked at your thingiverse pages, also your other 3D-printend engine.
The files are for Openscad, and I see .stl files for printing.
Can you send files in another format? At school we use Solidworks. I can open .Stl files, but then I can't modify then.
I'd like to review the parts, be able to make a few slight changes to account for specific parts.
Maybe I just design my own one, but it would sure be cool to have something to start from. you did nice work.
We have a 3D-printer here at school wich I sure can use when I talk to the man of the workshop. Nice way to build something nice real fast.
Just set the printer to work, and then assemble.

Thanks in advance,

Krijn

Hi Krijn,

Sorry the source files are in openscad.
Try maybe to install openscad (it's free) there might be other options to export to solidworks than .stl ?

Good luck
Cheers
