Description

I'm a fist year student at the Fontys School of Fine and Performing Arts in the Netherlands. And after building two real wooden marble machines which you can find in the links below, I couldn't wait to explore the possibilities of 3D printing.

So I decided to model a marble machine for everybody. After a lot of tweaking I can say it is finally perfect and, easy printable for everybody.


I used a Ultimaker2.

(And please do me the favor of uploading or sending me a photo when you printed is, 

i am collecting those pictures :)


Two wooden marble machines:

Materials and methods

OPTICAL PRINTING SETTING:

1 - The Gears: (IMPORTANT to print all gears at once, and not one at a time.)


Layer hight 0.1 (mm)

Shell thickness: 1.2 (mm)




Fill: 40%


Print speed: 40%

No support



2 - The Base:

 Layer hight 0.12 (mm)

Shell thickness: 1.2 (mm)

Fill: 10%


Print speed: 40%


No support


3 - The Floor:


Layer hight 0.1 (mm)

shell thickness: 1.2 (mm)


Fill: 40%

Print speed: 40%



No support

4 - 
The Track:

 Layer hight 0.1 (mm)


Shell thickness: 1.2 (mm)




Fill: 30%


Print speed: 40%



No support

In the videos I used chrome steel balls (used for ball bearings) with a diameter off 3.175 mm, which is 1/8"
But you could easily take some bigger ones. Only at the end of the track you will have to scrape off a bit of the opening. Which is really easy to do.

Result:
Pretty good. After a little clean up and drilling out the holes a bit it seems to work really nicely.
Feedback:
Simple Blue and green version. Video should be up soon at: https://vimeo.com/116106759

This is great - must give it a go and may even modify putting electric motor and gears on.
