Welcome to the lab, where we turn your questions into exciting experiments! Today, we’re diving into the world of 3D printing. Over the past few years, 3D printing has been seen as a game-changer in manufacturing, capable of creating everything from everyday items to food and even human organs. The industry is growing rapidly, and it’s an exciting time to learn about it!
3D printing is similar to how a regular printer works, but instead of just printing ink on paper, it builds objects by stacking layers on top of each other. Imagine making a loaf of bread by stacking slices one by one. This process allows for the creation of complex structures.
One of the coolest things 3D printing can do is create models of people. We visited My 3D in Toronto to try it out. First, we had to choose a pose. My 3D uses a special scanner that captures millions of data points every second. It projects a pattern onto our bodies and uses the changes in that pattern to create a 3D image of us.
As we posed, we could see our 3D images being built on the screen in real-time. An artist then refined these images to make sure they were perfect for printing. The final version, called a 3D mesh, is checked for any weak spots that might break during printing. Textures are added to show what the finished model will look like.
Our 3D models were printed using materials like gypsum or polymer clay. These materials are laid down layer by layer, hardened with a binder, and colored. The printing process takes a few hours. Once done, any extra powder is removed and recycled for future prints. The final touches include cleaning off remaining powder and applying glue to make the print sturdy and vibrant.
Finally, we got to see our 3D prints! It was amazing to see ourselves in miniature form. The details were incredible, showing even the patterns on our clothes. It felt like we were characters from a fantasy movie!
3D printing is a fascinating technology with endless possibilities. While it might not be in every home just yet, it’s definitely on its way. We want to thank My 3D Agency in Toronto for helping us create these awesome models. If you ever get the chance, give it a try—it’s a fun keepsake to have!
Stay tuned for our next experiment. See you next time!
Imagine you are a 3D artist! Use free online software like Tinkercad to design a simple 3D model of an object or character. Experiment with different shapes and structures, and try to visualize how your model would look when printed. This will help you understand the basics of 3D modeling.
Explore a 3D printing simulation game or app that allows you to experience the printing process virtually. Pay attention to how layers are built and how the printer operates. This activity will give you a better understanding of the mechanics behind 3D printing.
Plan a visit to a local makerspace or library that offers 3D printing services. Observe a 3D printer in action and ask questions about the materials and techniques used. Seeing the process firsthand will reinforce your understanding of how 3D printing works.
Work in groups to brainstorm and design a project that could be created using 3D printing. Consider practical applications, such as a tool or a decorative item. Present your project idea to the class, explaining the design and potential uses.
Conduct research on the future possibilities of 3D printing, such as in medicine, construction, or space exploration. Create a presentation or poster showcasing your findings and share it with the class. This will help you appreciate the vast potential of this technology.

Welcome back to the lab, where we take your questions and turn them into experiments! My name is Mitch, and I’m Greg. Today, we’re going to explore 3D printing. For the past half-decade, 3D printing has been predicted as the next revolution in manufacturing, from everyday objects to food and even organs. Last year, the 3D printing industry not only survived but actually grew.
3D printing works a lot like your traditional printer that prints ink on a page, but instead of printing one layer as ink, it stacks multiple layers on top of each other to build complex structures. It’s like making sliced bread but in reverse. After putting one layer down, another is built on top, and soon the entire object is created.
3D printing can do many amazing things, including creating 3D models of ourselves. So, we’re going to head over to My 3D in Toronto to do exactly that.
To start, we need to pick a pose. My 3D uses a structured light 3D scanner that works at 16 frames per second and captures 2 million points of information every second. It projects a known pattern onto our bodies and analyzes the deformation of that pattern to determine the shape of our bodies using triangulation.
As we pose, we can see pieces of our 3D image on the screen as the program digitally reconstructs us in real time. Our images need to be fully reconstructed and touched up by an artist. I went back to see our figurines come right out of the 3D printer.
Here is the final rendering of my 3D image before it was printed. This is called the 3D mesh, and it is checked for any fragile points that could potentially break during the printing process. Textures are then added to show what the final image will look like. Our 3D models are printed using gypsum or polymer clay, which is laid out layer by layer and hardened with binder and color.
The print takes a few hours to complete. Once finished, the excess powder is vacuumed out and recycled for future use, leaving us with the final print. The finishing touches include blowing off the remaining powder and applying a thin layer of glue to keep the print hard and enhance the colors.
Now that we have our 3D prints, we’re going to open them up and take a look for the first time. I’ve seen my figurine, but Greg hasn’t seen his yet.
Let’s see what we look like in miniature 3D!
Wow, this is so cool! I look like an elf, almost like I’m from a fantasy movie. The details are impressive, and you can see interesting patterns on the fabric.
Greg’s figurine even has a little detail on the front. This is really cool! We’ve been immortalized!
The concept of 3D printing is fascinating, and it has so many applications. There’s still a long way to go before it becomes a common household item, but it’s happening right now, and that’s exciting.
We want to thank My 3D Agency for letting us come and get these done. They’re located in Toronto, and we’ll put links in the description so you can check them out. Otherwise, give it a try; it’s a fun little keepsake to have.
We’ll see you next time for the next experiment. Peace!
