3D printing is becoming an increasingly popular way to introduce children to STEM through hands-on learning. Rather than simply looking at how technology works, children can see an idea take shape and become a physical object they can hold, explore and customise.
For children, 3D printing can be much more than making objects. It can encourage creativity, problem-solving, fine motor skills and an understanding of how everyday objects are designed and made.
At Seesaw STEAM, we use 3D printing and 3D printing pens to create practical, hands-on experiences that allow children to explore technology while making something of their own.
What Is 3D Printing?
3D printing is a process of creating a physical object layer by layer. Instead of cutting an object out of a larger material, a 3D printer builds it gradually until the finished object is formed.
This makes 3D printing particularly interesting for children because they can watch a digital or physical design become a real object.
Even at a basic level, learning about a 3D printer can introduce children to ideas such as:
Children do not need to become experts in 3D printing to benefit from these experiences. Simply understanding how a 3D printer works can help make technology more tangible and easier to understand.
1. Encourages Creativity
One of the biggest benefits of 3D printing for children is the opportunity to create something that is their own.
Traditional classroom activities often have a clearly defined finished product. With 3D printing, there can be much more room for personal ideas and creativity.
Children can think about:
3D printing pens take this idea even further. Instead of watching a machine create an object, children can directly control the material and build their own shapes, patterns and designs.
This gives children a very different relationship with technology. They are not just using technology — they are making something with it.
2. Develops Fine Motor Skills
Using a 3D printing pen requires children to control the movement of their hands carefully.
They need to think about where they are drawing, how quickly they are moving the pen and how much material they are adding. Creating small shapes and details requires coordination between their hands and eyes.
These activities can help children practise:
Because the activity results in a physical object, children can immediately see how their movements affect what they are creating.
3. Introduces Children to Engineering Concepts
3D printing provides a simple way to introduce children to basic engineering concepts without making the activity overly technical.
For example, children can explore why some shapes are stronger than others, how different parts can connect, and what happens when a structure is too thin, too large or not properly supported.
When using a 3D printing pen, children can experiment with creating:
These simple experiments can introduce the idea that engineering is about designing, testing and improving.
4. Builds Problem-Solving Skills
Not every 3D printing project works perfectly the first time.
A shape might not connect properly. A structure might be too weak. A design might not look the way a child expected.
Instead of seeing this as failure, children can learn to ask:
This is an important part of STEM learning. Children learn that creating something often involves trying, adjusting and trying again.
3D printing provides a safe and engaging way to practise this process because the results are visible and immediate.
5. Helps Children Understand How Things Are Made
Many of the objects children use every day are manufactured using different processes. However, manufacturing can be difficult to understand when it is only explained through pictures or words.
A 3D printer provides a simple visual example.
Children can watch an object being built layer by layer and begin to understand that physical products do not simply appear as finished objects. They are designed, constructed and assembled.
This can help children develop an early understanding of manufacturing and product design.
6. Encourages Patience and Focus
3D printing activities can also encourage children to slow down and concentrate.
When using a 3D printing pen, rushing can make it more difficult to create accurate shapes or detailed designs. Children need to pay attention to their movements and make small adjustments as they work.
The activity therefore combines creativity with concentration.
For many children, there is also a strong sense of achievement when they finish something they have created themselves.
7. Makes STEM Learning Hands-On
One of the most valuable aspects of 3D printing is that it turns abstract STEM concepts into something children can physically experience.
Instead of only learning about technology, children can:
See it → Touch it → Make it → Test it → Improve it
This hands-on approach can make STEM learning more memorable and engaging.
3D printing can bring together elements of science, technology, engineering, art and mathematics in one activity, making it a natural fit for STEAM education.
3D Printing Pens: A Different Way to Create
A 3D printer and a 3D printing pen offer two different experiences.
A 3D printer can create a carefully designed object automatically, while a 3D printing pen allows children to directly control the creation process.
With a 3D printing pen, children can draw with melted filament and build up their designs by hand. This makes the technology more accessible and interactive.
For younger children in particular, a 3D printing pen can be an exciting introduction to the basic idea of additive manufacturing: adding material to gradually create an object.
It also gives children more freedom to experiment with their own ideas.
Learning Through Making
Perhaps the most important benefit of 3D printing is that it gives children an opportunity to learn through making.
They can explore how a machine works, experiment with materials, create their own designs and solve problems along the way.
The finished object is only part of the experience. The process of thinking, creating, testing and improving is where much of the learning happens.
For children, 3D printing is therefore not just about technology. It can be a creative and practical way to develop curiosity, confidence and problem-solving skills while introducing them to the world of STEM.
Bringing 3D Printing Into Children's Learning
3D printing can be used in many different educational settings, from schools and kindergartens to OSHC and holiday programs.
At Seesaw STEAM, our 3D printing incursions are designed to give children a practical introduction to 3D printing and 3D printing pens. Children get the opportunity to explore how 3D printing works, experiment with materials and create something they can take pride in.
By combining technology with creativity and hands-on making, 3D printing can turn a simple activity into a memorable STEAM learning experience.
