High RPM Pneumatic Engine – Engineeering Demo
Print Profile(1)
Description
This is a fully working 3D printed air motor using a wobble cylinder design.
It’s not just a model—it actually runs at high RPM using compressed air.
Designed as both a hands-on STEM project and a display-worthy mechanical build, this motor demonstrates real engineering principles in a compact, printable format.
🔧 Key Features
- Fully functional wobble cylinder mechanism
- Runs smoothly at high speed
- Uses real ball bearings for reduced friction
- Designed to work primarily with PLA
- Detailed 40+ page build and operation manual
📘 What You’ll Learn
- Pneumatics basics
- Rotary motion and mechanical timing
- Friction reduction using bearings
- Real-world assembly techniques
🛠 Build Info
- Includes full material list (bearings, fittings, tubing)
- Step-by-step instructions with real photos
- No special tools required beyond a typical hobby setup
This is an original design created from scratch.
If you’re into functional prints, engineering projects, or just want something unique that actually moves, this is a rewarding build.
