Introduction: 3D Printed Water Motor

This is a water motor, connect a water pipe to the motor and then it works. It's very simple. I made this, because I wanted to make a mecanical project with fusion 360.

If you like my Instructable, don't forget to vote for me in the contests. :) Thanks!

Step 1: How I Made It?

I am a beginner with Fusion 360, I wanted to make a difficult project to train myself at Fusion 360. It tooks me 3 days to draw this object.

Step 2: How It Works?

It 's a simple concept, there is a gear inside the motor, when the water flows the gear turns and a gear system lowers motor speed and increases torque.

Step 3: How to Make It?

If you want to make it, you can download the stl files, and you can print it.

Use Nut with seal, it's important. All the bolts have a diameter of 4 mm.

I print this with the K8200 printer, and I use Cura to generate the G-code.
My Print settings:

  1. Bottom/Top thickness 0.6mm
  2. Fill Density 20%
  3. Platform adhesion type: none
  4. Support type: Don't use support!
  5. Use PLA or ABS.

If you want to modify this design you can download the Fusion files with this link: http://a360.co/2sOvVtE

hope you enjoyed reading this instructable. :)

I am 16 years old and I speak french, excuse me if I made errors of English in this instructable.

Neat. It'd be useful to power one of those swinging automatic sprinklers or whatever they're called

Nice. You could use it to drive a water pump.

That pumps water into itself!

Holy smokes! Y'all just invented an unlimited free energy machine the government doesn't want you to know about.

Does this have enough torque to turn a small generator (like the kind you would find on a bicycle for headlights)?

When there is a lot of water pressure, you can easily run a small generator.

This is a great project. You've included several fundamental concepts of physics seamlessly in one simple mechanism, excellent work. This could be the start of a very effective, programmable lawn sprinkler or other useful device. Your turbine is using a mix of viscosity and momentum that you can more precisely control without much modification to your current design. You have most of an impulse turbine. Consider improving your design to (1) create controlled momentum and (2) take advantage of that momentum in a controlled fashion. Google "Pelton Wheel" and "impulse turbine".

Nice machine. Would energy transfer (efficiency) be improved if the the water went all the way round the top, instead of the short cut across the bottom of the chamber ? (Like a turbine in a dam ?)

Small technical point: your gearing increases torque, not power (and reduces speed). Gearing always reduces power, because of frictional losses.

I can't answer your first question (I have no idea, sorry) ;)

You're totally right about the technical point. I misspoke.
