What is this?
This is a 3D printed Jet Engine Model – Large Size – BLACK EDITION (JET-LB)
A jet engine is a magnificent machine that burns energy-rich liquid fuel and releases 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.
Although a jet engine is a very complex machine, its working principles can be explained using four simple terms:
- SUCK As the fan rotates, air is drawn in at the front through an inlet or intake
- SQUEEZE Some of the air travels into the core of the engine and gets compressed
- BANG When the compressed air travels to the combustion chamber, it is mixed with fuel and combusted, producing hot gases
- BLOW The hot gases exit the combustor into the turbine, where its energy is extracted and used to drive the compressor and the fan
We designed this model to help explain how a generic 3-shaft jet engine works. The design of the model has been constantly evolving since the project completed. The JET-LB, is an upgraded version of the original design JET-LE.

How was this model designed?
This model was designed using publicly available material from the internet including CAD models, videos and pictures of the real jet engines from various aerospace companies. The final 3D printed Jet Engine model has more than 100 3D-printed parts fitted together perfectly. It also has a number of modules and each module was built independently and assembled together at the end in a very similar manor as to how a real jet engine is built.
* I was inspired by the 3D Printable Jet Engine by CATIAV5FTW, that’s why some parts on my model may look similar to his.
What makes this model perfect for STEM education?
The 3D printed Jet Engine model JET-LB is an excellent kit for STEM engagement because:
- It helps capture the attention of young students instantly and engage with them more effectively
- It helps students better understand how a Jet Engine works in simple terms by being able to explore a physical model and interact with it rather than just looking at pictures or CAD model of an engine
- 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
- The model is an excellent representation of a real jet engine, meaning it can be used to engage with audiences of all age groups, from very young kids to professionals
- Finally, with its large size, high level of detail, excellent quality and finish, this model can absolutely be used as a super impressive display model!
What are the differences between the JET-LB and the JET-LE?
The JET-LB has a number of additional features and upgraded features that aren’t available on the JET-LE version:
- The JET-LB model has a stunning matte black fan instead of glossy turquoise blue as on the JET-LE version
- The JET-LB model has a more realistic-looking External Gearbox, located underneath the fan case
- The JET-LB model has an EEC (Electronic Engine Controller) mounted outside the fan case using magnets which are completely detachable
- The JET-LB model has a rear engine mount, fitted on top of the tail bearing housing via M4 screws
- The JET-LB model has two thrust links, located between the rear engine mount and the intermediate case
- The JET-LB model also comes with a 3D-printed human figure, which can be placed anywhere around the model to illustrate the true scale of the real engine
- The front support on the stand has a better design to give the model better stability and to make the external gearbox visible when look from the front
- The engine build stand is printed in a bespoke deep lime colour, which represents the true colour of the real engine build stand
Frequent questions
-
How can I purchase / downlaod the STL for this model?
We currently don’t sell the STL for this model at the moment. However, this may be temporary only. Please check back in the future.
-
Do all the blades spin?
Yes, they do.
-
Can I spin the fan manually?
Yes, you can.
-
Can the fan / blades be driven by a motor?
Yes, all the blades on this model (including the fan) rotate together at the same speed and can be driven by a single motor (hidden inside the Exhaust Nozzle)
-
What is the optional motor rpm?
10 rpm as standard but can be swapped for a slower or faster motor.
-
Can the motor be removed when not in use?
Yes, the motor is hidden inside the Exhaust Nozzle and can be removed easily.
-
Does the model have any internal components?
Yes, it does – a section of the outer casing can be removed to reveal the internals of the model.
-
Can the model be stripped down?
No, most parts are glued together permanently. Only a few external parts can be removed.
-
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.
