Jet Engine Model - Medium Size - Design #1 (Product ID: JET-M1)
What is this?
This is a 3D printed Jet Engine Model – Medium Size – Design #1 (Product ID: JET-M1)
A jet engine is a magnificent machine that burns energy-rich, liquid fuel and release hot exhaust gas to generate an extremely powerful pushing force called thrust. The thrust pushes a plane forward and take you to your desired destinations across the Globe.
In 2018, to support my STEM activities and help explain to young students how a Jet Engine works, I decided to give myself a project: “Design and Make a 3D printed Jet Engine Model“. The project took me over 6 months to complete (as I did it entirely in my spare time after work).
As the final model being really big and complex (See 3D printed Jet Engine model EXTREME Version or BLACK EDITION), there is a need for a smaller and simpler model that can be transported with ease and also given away at STEM events as prizes. In May 2019, after my very first visit to 3DGBIRE and the CREATE Education Project to meet some amazing people, I was inspired to bring this model to life.
I wanted to shrink my original Jet Engine Model to half of its original size. However, as you all know, with 3D printing (especially if you print with a FDM/FFF printer), you can’t just simply scale down any design significantly and still expect a perfect print – this is because some features may become too small to print. To overcome this issue, I had to re-design most of the casing to ensure that even the smallest feature can be printed beautifully. In addition, to keep the model as simple as possible but still looks gorgeous, I removed almost all internal components except the Fan in the front and the Fan Shaft. After hours and hours modifying the design, I shrunk the new model down to 50% and hit “print”. The model came out absolutely beautiful! Although it’s much smaller than the original model, I managed to retain every details on the casing, meaning that you can still look at the outer casing and distinguish between each module of the engine. The model doesn’t have any internal components but it has a beautiful Fan which can be rotated either by hand or driven by a small motor hidden inside the Exhaust Nozzle.

What can this model be used for?
The 3D printed Jet Engine model JET-M1 is an excellent STEM model because:
– It helps capture attention of young students instantly and engage with them more effectively.
– It helps the students better and quicker understand how a Jet Engine works in simple terms by being able to explore a physical model and interact with it (rather than looking at pictures or CAD model of an engine via an App on phones or tablets).
– The model is made by 3D printing, hence, it helps spark interesting conversations with the students about how technologies (such as additive manufacturing) are revolutionising the Engineering Industry today and how they can learn the skills that would benefit their careers in STEM in the near future.
– Finally, with its small size, as well as excellent quality and finish, this model can also be used as an award, trophy, gift or simply a super cool item in your personal aerospace collection!
1, Does the Fan spin? Yes, it does
2, Can I take the Engine off the Stand? Yes
3, Can I spin the Fan manually? Yes – but only when the motor is removed
4, Can the Fan be driven by a motor? Yes, the motor is an optional upgrade
5, What is the motor rpm? 10 rpm as standard but can be swapped for a slower or faster motor
6, Can the motor be removed when not in use? Yes, the motor is hidden inside the Exhaust Nozzle and can be removed easily
7, Does the model has any internal components? No, it doesn’t. Only the Large Size models have internal components
8, Can the model be stripped down? Yes, except the Fan and the Fan Shaft (these two parts are glued together)
9, Does it work like a real jet engine? No, this is only an educational model so please don’t put it on your RC airplane 🙂
